The City of Modesto operates a 20 MGD two-plant treatment system, with primary treatment at the Sutter Plant and secondary/tertiary treatment at the Jennings Plant. In recent years, the City has faced escalating odor complaints near Sutter, severe hydrogen sulfide (H₂S)-driven corrosion at Jennings, and seasonal ultraviolet transmittance (UVT) drops that jeopardize recycled water compliance. This study integrated field investigations, bench testing, and technology evaluations to develop an adaptive, tiered plan addressing all three challenges concurrently.
Comprehensive monitoring in four major trunk sewers and both plants quantified sulfide mass loads, confirmed two major trunks as dominant contributors (>80% of load to Sutter), and documented extreme H₂S levels at Jennings—averaging over 100 ppm and peaking above 700 ppm at fine screens. UVT declines were found to coincide with seasonal blending of high-BOD, low-pH cannery wastewater with domestic flows, introducing lignins, tannins, and potentially UV-absorbing artificial sweeteners. LC-MS confirmed the presence of five sweeteners in UV influent, though their individual impacts remain to be quantified.
A broad suite of odor/corrosion control options was screened against technical, operational, cost, and UVT-risk criteria. Chemicals with potential toxic by-products or proven UVT impairment were eliminated. Life-cycle analysis showed pure oxygen injection to be 3–6x less costly than chemical dosing for major trunk applications, with nanobubble oxygenation offering potential dual benefits for odor suppression and UVT improvement.Bench-scale ECO₂ oxygenation tests validated rapid, complete dissolved sulfide removal within 30 minutes and confirmed low oxygen uptake rates, supporting conservative system sizing. The recommended adaptive plan applies a tiered approach: (1) immediate oxygen injection installation at Woodland and Thousand Oaks lift stations; (2) Sutter biofilter optimization, and nanobubble pilot testing; (3) targeted force main treatment via nanobubbles, oxygen injection, or nitrate dosing; and (4) end-of-line H₂S capture at Jennings via biotrickling filters.
Parallel UVT mitigation tiers included reverse blending to isolate cannery flows, nanobubble piloting, targeted compound source characterization, and long-term industrial source control via pretreatment or sewer-use by-laws. This integrated, data-driven strategy enables Modesto to phase investments, respond adaptively to performance data, and meet both odor/corrosion and recycled water reliability goals within operational and financial constraints.
Learning Objectives:
After the presentation, participants will be able to diagnose odor, corrosion, and UVT challenges using field data and source identification techniques
After the presentation, participants will be able to compare the cost, performance, and UVT impacts of chemical, oxygen, and nanobubble treatment strategies
After the presentation, participants will be able to apply a tiered, integrated and adaptive planning framework to phase solutions that protect infrastructure and protect recycled water reliability"From Failing Septic Systems to Sustainable Futures: Sewer Solutions for Disadvantaged Communities in Sacramento County (Collections Reliability)
A new tool is available for concrete cylinder force main condition assessment: electromagnetic (EM) thickness testing. This tool does not require destructive methods that increase risk and defeat the purpose of assessment, nor does it require deployment of equipment on the inside of the pipe. V&A is piloting a technique developed in the oil and gas industry to use an EM probe on the outside of the pipe to measure metal thickness. Ross Valley Sanitary District's seven-mile force main system is about 42% reinforced concrete cylinder pipe (RCCP), with a steel cylinder surrounded by cement and outside steel reinforcing, installed between 1958 and 1986. RVSD would prefer avoidance of costly replacement if a non-destructive condition assessment technique would indicate more years of remaining service. The application of EM testing to a section of RCCP pipe along a known corrosion gradient will be presented, along with costs, equipment, procedures and results, and the potential application of EM testing in RVSD's broader condition assessment program will be discussed.
Learning Objectives:
Understand electromagnetic testing equipment, procedures, and costs, and how they relate to metal thickness of force main assets and their remaining useful life.
Understand how the study of a gradient of defective pipe, using corroded section of bypass force main, demonstrated the usefulness and sensitivity of EM testing to measure metal pipe thickness.
Evaluate whether to invest in electromagnetic testing as a targeted condition assessment tool and compare it with other force main condition assessment techniques and force main management approaches."A New Tool for Concrete Cylinder Force Main Condition Assessment - External Electromagnetic Thickness Testing (Collections Reliability)
The Sacramento Area Sewer District (SacSewer) spearheaded a critical infrastructure project to replace failing septic systems with public sewer service in five small, disadvantaged communities in Sacramento County. Many of the replaced septic systems were beyond their useful lifespan, unpermitted, or unable to meet modern regulatory standards, posing risks to public health and the environment. The project constructed approximately 51,660 linear feet of new sanitary sewer pipelines, enabling households to abandon outdated septic systems and connect to reliable public sewer service.
Given the financial hardships faced by these low-income communities, SacSewer successfully pursued local, state, and federal grant funding and other cost-sharing assistance to make sewer conversion available at no cost to the residential and school properties in these communities. This effort required extensive community engagement and education with the goal of residents and property owners understanding that converting to sewer service would not only alleviate septic system maintenance burdens and avoid increasingly stringent septic regulations, but also protect groundwater, bolster public health, and enhance their property values. SacSewer expects construction to conclude by the end of 2025 with successful implementation ensuring long-term environmental protection and equitable access to essential wastewater services in Sacramento County.
Presenters will share lessons learned in securing and coordinating funding, managing project schedules, and designing effective community engagement strategies.
Key takeaways will include:
• How to approach and structure successful funding applications and coordinate with multiple funding agencies

ML sits within the broader AI landscape and is particularly relevant for water applications due to its ability to handle structured and unstructured data, adapt to changing conditions, and uncover hidden insights. In water management, ML can be leveraged to predict equipment failures, optimize treatment processes, forecast influent flows, and enhance decision-making.
This presentation explores the evolving role of ML in the water sector, demystifies core concepts, and illustrates their application through real-world case studies. It also highlights the critical importance of data quality, system integration, and human factors for successful deployment. The presentation emphasizes that while ML may appear complex, it is fundamentally rooted in mathematical relationships and pattern recognition—making it accessible and highly valuable when applied correctly.
The presentation will provide a practical assessment of the ML algorithms gaining utility in the water industry and discuss the data requirements and challenges when implementing ML technologies. Four primary ML paradigms will be discussed: supervised learning, unsupervised learning, reinforcement learning, and deep learning. Real-world case studies will demonstrate the practical applications of ML in predicting influent flows and forecasting biogas production. The presentation will also provide an overview of the current state of ML applications in the water industry across five stages of maturity, from research/embryonic to mature applications. Finally, the presentation will highlight the challenges associated with poor data quality and the importance of a robust system architecture for successful ML deployment in the water industry.
Learning Objectives:
Understand the Role of AI and ML in the Water Industry: Gain insights into how AI and ML are transforming water resource management, infrastructure optimization, and operations.
Describe different ML paradigms and applications relevant to the water industry supervised learning, unsupervised learning, reinforcement learning, and deep learning.
Recognize the importance of data quality, system integration and human factors in the successful deployment of ML technologies in the water sector."Session 2: Bottlenecks and Breakthroughs: Developing AI Models for Optimizing Calera Creek’s Wastewater Treatment Operations
Arup and the City of Pacific worked together to develop two AI/ML models as proof of concepts for sequential batch reactor (SBR) and auto-thermal thermophilic aerobic digestion (ATAD) operations at the Calera Creek Water Recycling plant. Arup and City of Pacifica first identified opportunities through visualizing historic plant data and then developed, trained, and tested chosen models. The project conclusions highlight barriers to implementation of AI/ML in plant operations, and identified necessary next steps to overcome these obstacles.The Calera Creek Water Recycling Plant, located in Pacifica, California, is a critical facility that uses advanced SBR technology to efficiently combine aeration and clarification processes and ATAD technology to produce Class A sludge. These technical innovations allow the plant to meet the evolving challenges of wastewater treatment, nutrient removal, and environmental sustainability.
With the increasing complexity of its operations—especially during peak storm flows—there are a growing number of opportunities for advanced analytics, rooted in Artificial Intelligence and Machine Learning techniques, to optimize the plant’s operations. These include improving energy efficiency, enhancing process performance, and reducing the risk of unexpected faults or failures through managed predictive maintenance. This presentation will include insights from the Engineers, Operators, and Data Scientists’ perspective, as well as lessons learned from the project team when addressing challenges in developing optimization approaches towards SBR and ATAD operation.
The presentation will also cover how to effectively incorporate stakeholder input, pivot when presented with ambivalent results, and create roadmaps for effective integration of AI models in wastewater treatment plant operation.
Learning Objectives:
Develop strategies to encourage AI integration with existing wastewater treatment processes.
Recongnize bottlenecks to predictive AI/ML modeling for sequential batch reactor (SBR) and auto-thermophilic aerobic digester systems.
Manage uncertainty surrounding wastewater treatment plant data availability and quality."Session 3: Generative AI for Operations and Maintenance for Utilities
Water and wastewater utilities face mounting challenges—aging infrastructure, workforce shortages, and increasing operational complexity. Generative AI is emerging as a transformative tool to support operations and maintenance (O&M) by making institutional knowledge more accessible, improving decision-making, and boosting workforce efficiency.This session presents the development and deployment of a domain-specific Generative AI platform for utility O&M. The goal is to show how large language models (LLMs), integrated with structured utility data, can assist field crews, operators, and engineers in real time. The system—called a Knowledge Twin—uses retrieval-augmented generation (RAG) to deliver accurate, actionable responses to natural language queries on assets, procedures, alarms, and troubleshooting.
Currently piloted with multiple utilities, the platform accommodates varying levels of data maturity. Data sources such as CMMS records, SCADA logs, SOPs, GIS data, and work order histories are ingested, structured into a knowledge graph, and connected to a fine-tuned LLM trained on the terminology, context, and workflows unique to water and wastewater operations.
Early results show that field staff can resolve issues faster, locate information more easily, and preserve institutional knowledge despite staff turnover. Use cases include alarm response guidance, step-by-step maintenance support, asset history retrieval, and on-demand training. A key finding is the system’s ability to uncover insights from previously siloed or underused data, reducing time-to-resolution and unplanned downtime.
The approach is designed to start small—focusing on high-impact use cases—and scale as more data is curated or digitized. This lowers the barrier to entry, enabling utilities of all sizes to leverage AI without perfect datasets or major system changes.
The session will feature a live demonstration, practical deployment considerations, and lessons from early adopters. Attendees will leave with a clear understanding of how Generative AI can be safely and effectively implemented to enhance daily O&M, improve service reliability, and strengthen workforce capabilities.
As utilities confront aging infrastructure and the demands of digital transformation, Generative AI provides a powerful path to future-proof operations and empower the next generation of utility professionals.
Learning Objectives:
1. Understand what Generative AI is and how it applies specifically to utility operations and maintenance.
2. To see key operational use cases where Generative AI delivers measurable value.
3. To understand how AI tools using existing utility data—regardless of current data maturity."AC26 Recordings Sponsored By:

This series includes the following 50 minute sessions.Session 1: Protecting Infrastructure and Reuse Reliability: Integrated Adaptive Plan for Odor, Corrosion, and UVT
The City of Modesto operates a 20 MGD two-plant treatment system, with primary treatment at the Sutter Plant and secondary/tertiary treatment at the Jennings Plant. In recent years, the City has faced escalating odor complaints near Sutter, severe hydrogen sulfide (H₂S)-driven corrosion at Jennings, and seasonal ultraviolet transmittance (UVT) drops that jeopardize recycled water compliance. This study integrated field investigations, bench testing, and technology evaluations to develop an adaptive, tiered plan addressing all three challenges concurrently.
Comprehensive monitoring in four major trunk sewers and both plants quantified sulfide mass loads, confirmed two major trunks as dominant contributors (>80% of load to Sutter), and documented extreme H₂S levels at Jennings—averaging over 100 ppm and peaking above 700 ppm at fine screens. UVT declines were found to coincide with seasonal blending of high-BOD, low-pH cannery wastewater with domestic flows, introducing lignins, tannins, and potentially UV-absorbing artificial sweeteners. LC-MS confirmed the presence of five sweeteners in UV influent, though their individual impacts remain to be quantified.
A broad suite of odor/corrosion control options was screened against technical, operational, cost, and UVT-risk criteria. Chemicals with potential toxic by-products or proven UVT impairment were eliminated. Life-cycle analysis showed pure oxygen injection to be 3–6x less costly than chemical dosing for major trunk applications, with nanobubble oxygenation offering potential dual benefits for odor suppression and UVT improvement.
Bench-scale ECO₂ oxygenation tests validated rapid, complete dissolved sulfide removal within 30 minutes and confirmed low oxygen uptake rates, supporting conservative system sizing. The recommended adaptive plan applies a tiered approach: (1) immediate oxygen injection installation at Woodland and Thousand Oaks lift stations; (2) Sutter biofilter optimization, and nanobubble pilot testing; (3) targeted force main treatment via nanobubbles, oxygen injection, or nitrate dosing; and (4) end-of-line H₂S capture at Jennings via biotrickling filters.
Parallel UVT mitigation tiers included reverse blending to isolate cannery flows, nanobubble piloting, targeted compound source characterization, and long-term industrial source control via pretreatment or sewer-use by-laws. This integrated, data-driven strategy enables Modesto to phase investments, respond adaptively to performance data, and meet both odor/corrosion and recycled water reliability goals within operational and financial constraints.Learning Objectives:
After the presentation, participants will be able to diagnose odor, corrosion, and UVT challenges using field data and source identification techniques
After the presentation, participants will be able to compare the cost, performance, and UVT impacts of chemical, oxygen, and nanobubble treatment strategies
After the presentation, participants will be able to apply a tiered, integrated and adaptive planning framework to phase solutions that protect infrastructure and protect recycled water reliability"Session 2: From Failing Septic Systems to Sustainable Futures: Sewer Solutions for Disadvantaged Communities in Sacramento County
A new tool is available for concrete cylinder force main condition assessment: electromagnetic (EM) thickness testing. This tool does not require destructive methods that increase risk and defeat the purpose of assessment, nor does it require deployment of equipment on the inside of the pipe. V&A is piloting a technique developed in the oil and gas industry to use an EM probe on the outside of the pipe to measure metal thickness. Ross Valley Sanitary District's seven-mile force main system is about 42% reinforced concrete cylinder pipe (RCCP), with a steel cylinder surrounded by cement and outside steel reinforcing, installed between 1958 and 1986. RVSD would prefer avoidance of costly replacement if a non-destructive condition assessment technique would indicate more years of remaining service. The application of EM testing to a section of RCCP pipe along a known corrosion gradient will be presented, along with costs, equipment, procedures and results, and the potential application of EM testing in RVSD's broader condition assessment program will be discussed.
Learning Objectives:
Understand electromagnetic testing equipment, procedures, and costs, and how they relate to metal thickness of force main assets and their remaining useful life.
Understand how the study of a gradient of defective pipe, using corroded section of bypass force main, demonstrated the usefulness and sensitivity of EM testing to measure metal pipe thickness.
Evaluate whether to invest in electromagnetic testing as a targeted condition assessment tool and compare it with other force main condition assessment techniques and force main management approaches."
Session 3: A New Tool for Concrete Cylinder Force Main Condition Assessment - External Electromagnetic Thickness TestingThe Sacramento Area Sewer District (SacSewer) spearheaded a critical infrastructure project to replace failing septic systems with public sewer service in five small, disadvantaged communities in Sacramento County. Many of the replaced septic systems were beyond their useful lifespan, unpermitted, or unable to meet modern regulatory standards, posing risks to public health and the environment. The project constructed approximately 51,660 linear feet of new sanitary sewer pipelines, enabling households to abandon outdated septic systems and connect to reliable public sewer service.
Given the financial hardships faced by these low-income communities, SacSewer successfully pursued local, state, and federal grant funding and other cost-sharing assistance to make sewer conversion available at no cost to the residential and school properties in these communities. This effort required extensive community engagement and education with the goal of residents and property owners understanding that converting to sewer service would not only alleviate septic system maintenance burdens and avoid increasingly stringent septic regulations, but also protect groundwater, bolster public health, and enhance their property values. SacSewer expects construction to conclude by the end of 2025 with successful implementation ensuring long-term environmental protection and equitable access to essential wastewater services in Sacramento County.
Presenters will share lessons learned in securing and coordinating funding, managing project schedules, and designing effective community engagement strategies.
Key takeaways will include:
• How to approach and structure successful funding applications and coordinate with multiple funding agencies
• Strategies for building property owner trust and participation
• Critical lessons from construction document requirements and permitting
• Team collaboration practices between owners, SacSewer, funding agencies, and design and funding consultants that improved project delivery
The session will be interactive, using tools such as Mentimeter to engage the audience through live polls and Q&A. Attendees will leave with both immediate, actionable strategies for their own projects and broader lessons for sustaining long-term infrastructure improvements in underserved communities.
Learning Objectives:
Upon completion, participants will understand and know how to approach and structure successful funding applications and coordinate with multiple funding agencies.
Upon completion, participants will know strategies for building property owner trust and participation.
Upon completion, participants will know lessons from construction document requirements and permitting as well as team collaboration practices between homeowners, SacSewer, funding agencies, and consultants that improved project delivery."AC26 Recordings Sponsored By:

Among these, artificial intelligence (AI) is emerging as a powerful and disruptive technology to address challenges in water resource management, infrastructure optimization, and operations. AI models' ability to learn from and predict patterns directly from data, examples, and experience, rather than relying on mechanisms or pre-defined rules, makes this technology highly applicable to the water industry.
Machine learning (ML) is a subset of AI that enables systems to learn from data and improve performance over time without explicit programming. ML sits within the broader AI landscape and is particularly relevant for water applications due to its ability to handle structured and unstructured data, adapt to changing conditions, and uncover hidden insights. In water management, ML can be leveraged to predict equipment failures, optimize treatment processes, forecast influent flows, and enhance decision-making.
This presentation explores the evolving role of ML in the water sector, demystifies core concepts, and illustrates their application through real-world case studies. It also highlights the critical importance of data quality, system integration, and human factors for successful deployment. The presentation emphasizes that while ML may appear complex, it is fundamentally rooted in mathematical relationships and pattern recognition—making it accessible and highly valuable when applied correctly.
The presentation will provide a practical assessment of the ML algorithms gaining utility in the water industry and discuss the data requirements and challenges when implementing ML technologies. Four primary ML paradigms will be discussed: supervised learning, unsupervised learning, reinforcement learning, and deep learning. Real-world case studies will demonstrate the practical applications of ML in predicting influent flows and forecasting biogas production. The presentation will also provide an overview of the current state of ML applications in the water industry across five stages of maturity, from research/embryonic to mature applications. Finally, the presentation will highlight the challenges associated with poor data quality and the importance of a robust system architecture for successful ML deployment in the water industry.
Learning Objectives:
Understand the Role of AI and ML in the Water Industry: Gain insights into how AI and ML are transforming water resource management, infrastructure optimization, and operations.
Describe different ML paradigms and applications relevant to the water industry supervised learning, unsupervised learning, reinforcement learning, and deep learning.

CWEA Contact Hours: 1.0 contact hours towards CWEA Certifications: EITArup and the City of Pacific worked together to develop two AI/ML models as proof of concepts for sequential batch reactor (SBR) and auto-thermal thermophilic aerobic digestion (ATAD) operations at the Calera Creek Water Recycling plant. Arup and City of Pacifica first identified opportunities through visualizing historic plant data and then developed, trained, and tested chosen models. The project conclusions highlight barriers to implementation of AI/ML in plant operations, and identified necessary next steps to overcome these obstacles.
The Calera Creek Water Recycling Plant, located in Pacifica, California, is a critical facility that uses advanced SBR technology to efficiently combine aeration and clarification processes and ATAD technology to produce Class A sludge. These technical innovations allow the plant to meet the evolving challenges of wastewater treatment, nutrient removal, and environmental sustainability.
With the increasing complexity of its operations—especially during peak storm flows—there are a growing number of opportunities for advanced analytics, rooted in Artificial Intelligence and Machine Learning techniques, to optimize the plant’s operations. These include improving energy efficiency, enhancing process performance, and reducing the risk of unexpected faults or failures through managed predictive maintenance. This presentation will include insights from the Engineers, Operators, and Data Scientists’ perspective, as well as lessons learned from the project team when addressing challenges in developing optimization approaches towards SBR and ATAD operation.
The presentation will also cover how to effectively incorporate stakeholder input, pivot when presented with ambivalent results, and create roadmaps for effective integration of AI models in wastewater treatment plant operation.
Learning Objectives:
Develop strategies to encourage AI integration with existing wastewater treatment processes.
Recognize bottlenecks to predictive AI/ML modeling for sequential batch reactor (SBR) and auto-thermophilic aerobic digester systems.
Manage uncertainty surrounding wastewater treatment plant data availability and quality.AC26 Recorded Sessions Sponsored By:

CWEA Contact Hours: 1.0 contact hours towards CWEA Certifications: CSM, MT, LAB, EITWater and wastewater utilities face mounting challenges—aging infrastructure, workforce shortages, and increasing operational complexity. Generative AI is emerging as a transformative tool to support operations and maintenance (O&M) by making institutional knowledge more accessible, improving decision-making, and boosting workforce efficiency.
This session presents the development and deployment of a domain-specific Generative AI platform for utility O&M. The goal is to show how large language models (LLMs), integrated with structured utility data, can assist field crews, operators, and engineers in real time. The system—called a Knowledge Twin—uses retrieval-augmented generation (RAG) to deliver accurate, actionable responses to natural language queries on assets, procedures, alarms, and troubleshooting.
Currently piloted with multiple utilities, the platform accommodates varying levels of data maturity. Data sources such as CMMS records, SCADA logs, SOPs, GIS data, and work order histories are ingested, structured into a knowledge graph, and connected to a fine-tuned LLM trained on the terminology, context, and workflows unique to water and wastewater operations.
Early results show that field staff can resolve issues faster, locate information more easily, and preserve institutional knowledge despite staff turnover. Use cases include alarm response guidance, step-by-step maintenance support, asset history retrieval, and on-demand training. A key finding is the system’s ability to uncover insights from previously siloed or underused data, reducing time-to-resolution and unplanned downtime.
The approach is designed to start small—focusing on high-impact use cases—and scale as more data is curated or digitized. This lowers the barrier to entry, enabling utilities of all sizes to leverage AI without perfect datasets or major system changes.
The session will feature a live demonstration, practical deployment considerations, and lessons from early adopters. Attendees will leave with a clear understanding of how Generative AI can be safely and effectively implemented to enhance daily O&M, improve service reliability, and strengthen workforce capabilities.
As utilities confront aging infrastructure and the demands of digital transformation, Generative AI provides a powerful path to future-proof operations and empower the next generation of utility professionals.
Learning Objectives:
1. Understand what Generative AI is and how it applies specifically to utility operations and maintenance.
4. To see key operational use cases where Generative AI delivers measurable value.
2. To understand how AI tools using existing utility data—regardless of current data maturity.AC26 Recorded Sessions Sponsored By:

CWEA Contact Hours: 1.0 contact hours towards CWEA Certifications: ALLStrong communication is not just about presenting information. It is about helping work move forward.
Early in their careers, many professionals discover that projects rarely stall because of technical challenges. More often, they slow down because expectations were unclear, updates were not shared, or stakeholders were left guessing about progress.
In this practical and engaging session, David Garrison shares communication strategies that help professionals keep projects on track, maintain trust with stakeholders, and guide tasks to completion.
Drawing from more than a decade working with associations, public agencies, and consulting teams, David explores how small communication habits can dramatically improve collaboration. Participants will learn how proactive updates, clear expectations, and simple communication rhythms can strengthen relationships and prevent misunderstandings before they occur.
Through real examples and interactive discussion, participants will leave with tools they can apply immediately to improve their effectiveness as communicators and project contributors.
Because in professional environments, the difference between frustration and trust is often just one message sent at the right time.

This series includes the following 50 minute sessions.Advancing Solids Thickening Through Suspended Air Application
In a recent project funded by California Energy Commission (CEC), an innovative thickening process -Suspended Air Flotation (SAF®)- was selected to be tested at demonstration scale. SAF® process presents a compelling alternative to traditional thickening methods considering its potential to reduce energy consumption and to separate emerging contaminants such as Per- and polyfluoroalkyl substances (PFAS).The SAF technique employs a suspension of micron-sized air bubbles, ranging from 7 to 50 µm, in water to attain a volumetric air content of 40 to 50%. These bubbles are coated with a thin layer of soap film derived from an electrically charged anionic or cationic surfactant. The charged bubbles offer a substantial interfacial area for the adsorption of oppositely charged flocculated wastewater solids. In practice, suspensions of charged bubbles are introduced into the flotation tank to interact with wastewater solids. The solids then ascend to the surface and are skimmed off. The clarified effluent is recirculated to the headworks.
SAF enhances traditional thickening methods like Dissolved Air Flotation (DAF) by eliminating the need for dissolved air, thus obviating the requirement for pressurization systems, recirculation pumps, compressors, and airlines, leading to considerable energy savings. SAF's capability to manage high solids loads also results in substantial footprint and power savings, high solids recovery (up to 99%), and a high solids loading rate (up to 40 lb/ft2/hr). Moreover, no polymer is needed to thicken sludge to 4% solids. Owing to these benefits, adopting SAF technology can lead to an energy savings of up to 90% compared to its conventional counterparts, such as DAF.
This presentation will assess this novel technology, its performance, present results from case studies, and elaborate on the potential of this technology for PFAS separation.
Learning Objectives:
Define the suspended air flotation technology (SAF) and difference between dissolved air flotation (DAF) technology
Demonstrate the advancements of SAF technology for various case studies including thickening of Advanced primary treatment solids and secondary solids
List the important criteria for the design and operational challenges of the SAF technologyAnaerobic Digestion of Organics: Industry Drivers Overview of Two Case Studies for CHP and RNG
This presentation will discuss the diversion of organics, such as food waste and the co-digestion of these wastes with anaerobic digestion which generated biogas, a beneficial byproduct. Doing so allows reduction in landfill volumes and stabilization of the waste suitable for land application. The stabilization process, when accomplished with anaerobic digestion, generates biogas, a beneficial byproduct.The presentation will include an overview of industry trends, including regional trends in State of California for organics diversion requirements. Other industry drivers that will be covered will include greenhouse gas emissions reductions, state and federal financial incentives, and drivers for renewable energy production.
When organic waste is diverted to a wastewater treatment facility, the organics can be co-mingled with municipally generated sludge in anaerobic digestion (i.e., co-digestion). This allows for existing infrastructure to be utilized for both wastewater treatment and landfill diversion while generating a biosolids product and digester gas. The produced biogas can be utilized as a fuel source for a process heating boiler or in a combined heat and power system or renewable natural gas.
Finally, the presentation will include case study overviews of two functioning wastewater treatment facilities with anaerobic digestion, both which are receiving significant quantities of organic wastes to generate biogas from co-digestion. One facility is utilizing biogas produced in a combined heat & power (CHP) for use at the facility and has achieved net zero operations beginning in 2022. The second facility facility has a very large high strength waste program with over 19,000 loads received annually. The biogas from this facility is processing the biogas into renewable natural gas (RNG) for pipeline injection which generates over $6M annually.
Learning Objectives:
1. Gain understanding of the industry drivers for organics diversion and resource recovery programs.
2. Learn about two functioning full-scale wastewater treatment facilities with anaerobic digestion, both which are receiving significant quantities of organic wastes to generate biogas from co-digestion.
3. Define the concept the organics diversion, such as food waste and the co-digestion of these wastes with anaerobic digestion which generated biogas and potential value of this renewable fuel.
Maximizing Biosolids Value: Post-Upgrade Optimization and Market Development
This presentation explores the optimization of new solids handling facilities and the creation of marketable biosolids products, drawing insights from two major utilities: Hampton Roads Sanitation District (HRSD) and JEA.HRSD’s Atlantic Treatment Plant (ATP) transitioned from Class B to Class A biosolids production by commissioning a Cambi thermal hydrolysis process (THP) skid in mid-2020. This transition resulted in increased solids capacity and improved final dewatering performance. The presentation will delve into the startup and optimization process, highlighting lessons learned and how these upgrades have prepared HRSD to adapt to future regulatory changes.
Initial startup required ATP to disinfect digesters and all associated piping. The first digester was filled with heated disinfected non-potable water and seed from DC Water’s digesters. The approach to ramping up thermally hydrolyzed sludge feed started at 50% of DC Water’s loading rate and increased over several weeks.
Using existing dewatering centrifuges, the final dewatering cake solids improved from 14-16% total solids (TS) to 30% TS after THP implementation and optimization. Curing pilots using the 30% cake and a windrow turner determined the most efficient method for producing a low-odor, aerobically cured product. Lessons from 2023 pilot studies have been applied to full-scale curing operations initiated in early 2024.JEA, one of Florida’s largest utilities, has proactively planned for the future of their biosolids program. In 2017, JEA’s master plan recommended decommissioning the old thermal drying system and outsourcing Class B dewatered cake processing to a third-party. However, this dependence led to uncertainties in costs and regulatory compliance.
In 2020, JEA revised their strategy, recommending a new regional biosolids handling facility at the Buckman Water Reclamation Facility (BWRF). This facility, designed to handle solids from all 12 JEA-owned water reclamation facilities, includes advanced thickening and dewatering equipment, two large thermal drum drying systems, and infrastructure for high-quality pellet production. These upgrades provide JEA with the flexibility to pivot as regulatory drivers change and new market opportunities arise.
The presentation will discuss innovative strategies employed by JEA, including a pilot of an in-line high-shear dynamic mixer to re-wet dewatered cake solids, reducing transportation costs and capital expenses.
Learning Objectives:
Describe the startup and optimization process of thermal hydrolysis and its impact on biosolids capacity and quality.
Explain approaches to evaluating and upgrading biosolids handling facilities, focusing on infrastructure, process reliability, and market development.
Identify key lessons learned in the production and market development for biosolids products."Developing Engineering Design Criteria for Partial Denitrification Anammox (PdNA) Implementation for Multiple Biofilm Media
Partial denitrification anammox (PdNA) implementation can combat some of the most difficult challenges facing California’s water resource recovery facilities (WRRFs). PdNA can alleviate strains caused by population growth and nutrients, while offering long-term budgetary benefits. Rather than using traditional nitrification and denitrification, PdNA can be implemented which has lower energy requirements, carbon demands, and greenhouse gas emissions. In PdNA, nitrate is reduced to nitrite (partial denitrification), and the reduction of nitrite to nitrogen gas (full denitrification) is avoided. The nitrite produced from partial denitrification can then be reduced to nitrogen gas with influent ammonium via anammox. This process has been proven to be more stable than alternative methods (partial nitritation anammox [PNA]), making it an attractive option for mainstream wastewater treatment.This presentation will provide an overview of a $4 million U.S. Department of Energy (DOE) PdNA study that will implement PdNA in six WRRFs nationwide. The study focuses on determining engineering design criteria as nitrogen loading and removal rates, mixing requirements, headloss, fill ratios, and retrofittability of different media (moving integrated fixed-film activated sludge [IFAS], fixed IFAS, and biological aerated filters [BAFs]) to enable widespread PdNA implementation.
Applicability to California Utilities:
PdNA implementation can be a beneficial solution for California utilities that are seeking to increase capacity or are considering the initiation of a water reuse program. The capacity enhancement holds particular significance for facilities with footprint limitations, as PdNA can be retrofit into existing facilities without significant construction. From the perspective of water reuse, tertiary PdNA in a BAF offers a solution for achieving effluent total inorganic nitrogen (TIN) and total suspended solids (TSS) limits while minimizing modifications to upstream infrastructure.As a part of the DOE study, a pilot-scale tertiary BAF PdNA process will be evaluated at the Linda County Water District water resource recovery facility (WRRF) which should commence in Fall 2024. Startup and preliminary results from this pilot and other WRRFs will be shared at the conference.
Conclusion:
PdNA represents a cost-effective method for expanding capacity, reducing operation and maintenance costs, and transitioning to water reuse, making it a valuable solution for California utilities.
Learning Objectives:

Presentation Description: San Francisco Bay Area wastewater utilities are facing nutrient discharge regulations that impact near-term and long-term decision making. The City of Sunnyvale Water Pollution Control Plant (WPCP) balanced aging infrastructure needs with future nutrient to develop a phased approach for upgrading their treatment plant to remove nutrients.The existing treatment facilities at the WPCP are aging assets and cannot meet anticipated future discharge regulations for nitrogen. The City decided to be an early adopter in nutrient reduction and to implement a two-phased secondary treatment upgrade to transition to a conventional activated sludge (CAS) BNR process. Carollo/Jacobs recently completed the design for the $300M Secondary Treatment and Dewatering Project. The construction of the Phase 1 secondary treatment facility and Demon deammonification sidestream treatment facility is in progress. The CAS facilities will operate in parallel with the existing oxidation pond treatment train and the Demon sidestream facility will treat return stream from a new dewatering process.
Dealing with aging infrastructure and a tight site, this phased approach allows the City lots of flexibility. Delaying the second phase of the project allows the City to:
• Defer costs and maintain financial flexibility
• Allow process intensification technology to mature
• Maximize site space and right size phase 2
This presentation will provide an overview of the project and review key factors that influenced the decision to implement split flow and sidestream treatment, and explore elements of the design that were implemented to successfully manage the split flow operation and flexibility for future expansion.
This presentation may be of interest to design engineers, decision makers, planners, or others charged with navigating future regulations and developing strategies to optimize performance and nutrient load management. The City of Sunnyvale is on their way towards implementing their Program that began in 2016. Key decisions on implementing split flow and optimizing the Phase 1 Secondary Treatment and Dewatering Project design have maintained flexibility for the City for what comes next.
Learning Objectives:
Understand how a phased approach to a process upgrade can delay capital investment and increase future flexibility.
Identify creative solutions that address multiple drivers such as aging infrastructure and new regulations.
Describe the benefits of planning aheadModifying a BNR Facility for Low DO Operation and Operating it to Get There
The Los Angeles County Sanitation Districts and Carollo Engineers, Inc. have participated in a Department of Energy project called “Transforming Aeration Energy in Resource Recovery Facilities through Suboxic Nitrogen Removal.” The project seeks to operate the activated sludge process at dissolved oxygen (DO) levels that are significantly below 1.0 mg/L while maintaining nitrification. The aeration process in a water recovery facility (WRF) typically consumes approximately 50% of the total energy of the plant. This project aims to reduce that energy consumption from 1500 to below 650 Kwh/MGD . This project involved pilot work as well as conducting full-scale modifications at the Pomona WRF to accommodate low DO operation.The Pomona WRRF was built about 50 years ago and has not had any significant controls modifications since then. This may be typical of many WRF's in California. This presentation will cover in detail the significant modifications that were made to the facility and the costs. The old single speed centrifugal process air compressors were replaced with turboblowers. The old aeration control had one valve which controlled numerous aeration zones. New valves and flowmeters were installed to allow individual aeration zone control. A third-party control system was installed to allow precise DO control as well as ammonia-based aeration control. A solids retention time control system was also provided. To facilitate these control systems additional instrumentation, including sensors for ammonia, nitrate, DO, TSS, and sludge blankets, were installed. Details on the installation and maintenance of these sensors will be discussed.
The project team will also discuss the approach to reducing the DO while maintaining compliance. Results of low DO activated sludge transition will be presented. This project is due to be completed at the end of September 2024. Pomona WRF is currently operating an average daily DO of 0.85 mg/L. There is some disagreement about how low DO activated sludge works. It may be different organisms doing the nitrification or the existing population adapting to the low DO. The presentation will provide batch kinetic and nitrification test results as well as microbial analysis to try to provide an answer to that question.Learning Objectives:
Upon completion, the participant will be able to understand the equipment and controls required to perform low DO operation.
Upon completion, the participant will be able to formulate a plan to transition a facility to low DO operation.
Upon completion, the participant will be able to understand the costs and benefits associated with low DO operation.Addressing Future Uncertainties Through Adaptive Planning, Resulting in Intensification and Decarbonization of BNR
Adaptive planning serves as a valuable means to conceptualize and create designs for water resource recovery facilities (WRRFs) that accommodate various stages of growth, even those that are yet unknown. By offering flexible and high-performing technology options, intensification can assist in adaptive planning and effectively address the multiple challenges that WRRFs encounter today. This presentation will highlight the adaptable planning approach and intensification strategies implemented in the secondary treatment system design for the Town of Windsor Water District (Town) to:• decarbonize their biological nutrient removal (BNR) system in line with net zero sustainability goals
• plan for uncertain growth in a space constrained site
• meet stringent nutrient limits, both nitrogen and phosphorusThe Town’s WRRF has a limit for effluent total nitrogen and phosphorus in their NPDES permit (set at 10.5 mg-N/L and below detection limit respectively). While the WRF has been consistently meeting their permit, these stringent limitations have become constricting when considering Town’s ability to meet growth requirements. Current average influent TSS and ammonia loadings have already exceeded the WRRF’s design capacity. In addition, the Town will be consolidating with an adjacent sanitation district whose growth comes with a substantial degree of uncertainty.
The Town conducted a nutrient removal study and conceptual design in 2020, and is now implementing the detailed design of the secondary treatment system. A roadmap will be presented of the adaptive planning design for this system, which considers multiple growth scenarios for each of the Town’s influent sources.
A variety of intensification options were considered in the design, including aerobic granular sludge (AGS), primary filters and hydrocyclones. Membrane aerated bioreactors (MABR) were ultimately selected for their modular nature, low footprint, and low energy requirement, which perfectly aligns with the Town’s drivers above. The roadmap will illustrate how intensification strategies such as MABR can facilitate adaptive planning by providing phased growth design options that don’t necessarily mean expansion at each step. This part of the presentation will also include an audience driven discussion about how intensification strategies can more broadly be tailored to specific drivers, just as it was in Town’s adaptive design.
Learning Objectives:
View a roadmap of how adaptive planning can be used for phased design under uncertain and unexpected growth for WRRF’s with a multitude of drivers
Understand an example of how a specific intensification option can facilitate adaptive phased design and help tailor the design to a specific client’s needs
Describe how a variety of intensification options can meet various drivers for WRRFs including but not limited to: meeting permits, decarbonizing, address site specific challenges such as space constraints, etc."Benefits of Hydrocyclones for WRRF Performance: Better Settling, Improved Nitrification… and Reduced E. coli?!
The aerobic granular sludge activated sludge process using batch reactors has received attention for the potential it offers to intensify activated sludge. Intensification allows WRRFs to improve effluent quality with a smaller footprint. Alternate technologies like hydrocyclones have become commercially available, which help to retain faster settling particles while the slower-settling particles are wasted out of the system. This type of technology can be more easily incorporated into plug flow reactors. At some plug flow facilities that have both hydrocyclones and unaerated high food-to-microorganism (F/M) selector zones, a relatively high fraction of the activated sludge can become granules producing a “densified sludge”.In 2020, the City of Wichita installed a four-cyclone skid (180 gpm of return activated sludge [RAS]) on one of six nitrifying activated sludge trains at the Plant 2 WRRF (rated 54 million gallons per day [mgd]). The benefits to settleability through reductions in the sludge volume index (SVI) of the mixed liquor and improved water clarity in the test basin was observed. The SVI in the main basins averaged 120 mL/g compared to 91 mL/g in the hydrocyclone pilot basin. The City has started sampling E. coli in its secondary effluent prior to ultraviolet (UV) disinfection. Initial sampling has indicated about a 0.5-log reduction in E. coli counts in the hydrocyclone train compared to the non-cyclone trains.
Current biological nutrient removal (BNR) improvements project at the Plant 2 will incorporate a full-scale hydrocyclone system. This presentation will present the design criteria and layout of the new hydrocyclone facility and BNR facilities, a 5-stage Bardenpho process with high F/M selector zones and 19 cyclones for sludge wasting. Design considerations for the ancillary support facilities will also be presented, including a cyclone feed sludge (RAS) pumping, discharge of the cyclone underflow into the selector zones of the BNR process, and overflow as waste activated sludge (WAS).
With many utilities in California facing addition of nutrient limits in their discharge permit, the approach provided in this presentation will help these utilities save capital dollars on their improvement projects.
Learning Objectives:
Upon completion, participants will have a good understanding of densified sludge and the benefits it provides for wastewater plant operations.
Upon completion, participants will learn the key elements to consider when designing a full-scale hydrocyclone based system to provide densification in a plug flow reactor.
Upon completion, participants will learn about the latest research associated with hydrocylones, which indicates that they can potentially reduce disinfection dose at WRRFs, in addition to process benefits ."Registrants who view the live webinar to see the slides and hear the audio and then enter the correct attention check code (directions below) will receive 13.0.0 contact hours towards CWEA's certifications.

This series includes the following 50 minute sessions.Session 1: Inevitable Role of Secondary Treatment in Direct Potable Reuse Facilities
California DPR Regulations require ozone and biological active carbon (BAC) filtration ahead of full advanced treatment consisting of reverse osmosis (RO) and advanced oxidation process (AOP). The main purpose of ozone and BAC is to address low molecular weight organic compounds some of which such as acetone, formaldehyde cannot be effectively removed by the full advanced treatment. The other purpose of ozone-BAC is to provide an additional barrier for chemical peak “averaging”. While Ozone-BAC can provide an effective barrier for low molecular weight compounds that are poorly removed by full advanced treatment, the capabilities of ozone-BAC is limited to relatively small chemical peaking based on North City chemical spike studies. However, one critical area has not come to closer attention of State Water Board. That is the secondary treatment. In this presentation, we will explain inevitable role of secondary treatment in a DPR train. First, an activated sludge based secondary treatment can provide excellent removal for slowly biodegradable organic compounds such as acetone, formaldehyde and all other low molecular alcohols and ketones that are poorly removed by full advanced treatment. Second, a secondary treatment can provide nitrogen control which is critical to meet nitrite and nitrate nitrogen primary MCLs of 1 and 10 mg/L, respectively. These limits may not be reliably met in RO-based full advanced treatment if no nitrogen control is provided in the upstream wastewater treatment plant (e.g., Hyperion WRP). Third, a good nitrogen control is essential to minimize secondary effluent nitrite concentration which creates very high ozone demand during ozonation. Last but not least, a well-designed and operated secondary treatment can provide a high-quality effluent with reduced suspended solids, phosphate and metals which can create operational challenges at downstream advanced water purification facility (AWPF).In summary, how a robust secondary treatment along with performance requirements make DPR possible and case study examples will be presented to demonstrate how secondary process performance affects & defines AWPF design, performance & operation in a DPR train. It will provide an unmatched value for public and regulatory agencies to explore how secondary treatment that makes DPR projects more robust and resilient.
Learning Objectives:
To understand capabilities and limitations of ozone and BAC for chemical control in DPR projects
To understand role and superior benefits of activated sludge based secondary treatment in DPR
To understand how we can configure secondary treatment to make DPR projects more robust and resilientSession 2: Secondary Effluent Quality, Potable Reuse, and Nitrogen Removal: Considerations for Multi-Benefit Projects
Water reclamation facilities are facing a variety of new challenges, including the move toward potable reuse and new regulations to limit nitrogen discharges. This presentation explores the interactions between secondary effluent quality, potable reuse, and nitrogen removal.Successful potable reuse requires high-quality, consistent secondary effluent. The first part of this presentation will discuss typical advanced treatment trains for potable reuse and identify the critical design parameters impacted by the secondary treatment processes. Key differences between secondary treatment types will be quantified. The evaluation documents higher concentrations and higher variability in non-nitrifying facilities for several key parameters for potable reuse design, including total organic carbon (TOC), ammonia, and nitrite. For non-nitrifying plants, average TOCs ranged from 14 to 27 mg-N/L; nitrifying plants averaged 10 mg-N/L or less. Some non-nitrifying plants routinely reported nitrite concentrations above 2 mg-N/L, and even the fully nitrified facilities occasionally reported nitrite concentrations above 1 mg-N/L and ammonia concentrations above 2 mg-N/L. Plants considering potable reuse should begin monitoring TOC and nitrite to provide data for advanced treatment design. Optimization or upgrades to secondary treatment may be necessary, depending on the advanced treatment goals and requirements. The presentation will help planners and designers understand the suitability and challenges of their secondary effluent for potable reuse.
Plants with new nitrogen limits are considering multi-benefit solutions incorporating recycled water and potable reuse to reduce nitrogen discharges. The second part of this presentation will discuss the impact of potable reuse on nitrogen discharges. A variety of upgrade scenarios for a conventional BOD-removal only plant upgrading to potable reuse will be considered, and the impact on nitrogen removal will be quantified. Scenarios considered include different secondary treatment types (conventional BOD-removal like trickling filter solids contact and nitrification/denitrification in activated sludge), different management of reverse osmosis concentrate (discharge of concentrate, return of concentrate to the plant influent, and separate treatment of concentrate), and a range of potable reuse flows. Although each plant situation is unique, the results will help planners and designers understand the feasibility of using potable reuse to reduce nitrogen discharges and the key factors that impact nitrogen discharges.
Learning Objectives:
Upon completion, participants will be able to list three secondary effluent quality parameters key to potable reuse design.
Upon completion, participants will be able to describe the suitability and challenges of their secondary effluent for potable reuse.
Upon completion, participants will be able to understand the key potable reuse design decisions that impact nitrogen discharges.Session 3: Assessment of Virus Removal and Infectivity During Municipal Wastewater Treatment: Implications for Safe Reuse
Pathogen control and monitoring in water reuse applications is critical to public health protection and gaining public trust. As more utilities and water agencies consider implementing water reuse programs, obtaining credit for log reduction values (LRV) achieved through secondary and tertiary wastewater treatment processes will be an important consideration. While many utilities exploring reuse options are currently focused on membrane processes to achieve additional virus log removal credits, questions remain regarding LRV achieved through various conventional treatment trains. In addition, while molecular assays exist for the detection of viruses, the majority of these methods provide no information on culturability or infectivity thus making extrapolation of end-user exposure risk and identification of suitable applications challenging.
The objective of this study was to assess the removal of human infective viruses throughout the stages of wastewater treatment in a full-scale, tertiary municipal wastewater treatment plant in Canada. The plant resells 20% of its secondary effluent to an industrial partner after additional treatment by membrane filtration and chlorination. The remaining 80% of the secondary effluent undergoes UV disinfection prior to release into the environment. The partnership between the plant and the industrial partner produces 15 million liters of high-quality water for processing each day, which are used in the refinery cooling tower, boiler and hydrogen plant. Virus concentrations and infectivity were analysed using real-time quantitative PCR (qPCR) and integrated cell culture (ICC) to identify infective human viruses. Seven viruses including Norovirus (NoV), Rotavirus (RV), Sapovirus (SaV), Astrovirus (AsV), Adenovirus (AdV), Enterovirus (EV) and JC virus (JCV) were detected in 16 primary effluent samples in which infective viruses were present. Different treatment steps showed various efficiencies in infective virus removal, with membrane filtration exhibiting the highest at 4.6–7.0 log reductions.
The overall treatment virus LRV ranged from 1.1 (RV) to 2.8 (EV) for UV-treated final effluent and from 4.6 (EV) to 7.0 (AdV) when membrane filtration and chlorination were applied. The LRV for the six viruses (except for EV) by membrane filtration were significantly greater than that obtained by UV. EV had the highest inactivation by UV but the lowest by membrane filtration.Learning Objectives:
After the presentation, participants will be able to articulate the benefits and limitations of different viral testing methods and the potential value that coliphage testing might add.
After the presentation, participants will be able to compare the removal of viruses after various treatment steps.
After the presentation, participants will have more data to highlight the value and potential virus log removal credits that can be achieved by ultrafiltration (6–7 LRV).Registrants who view the live webinar to see the slides and hear the audio and then enter the correct attention check code (directions below) will receive 3.0 contact hours towards CWEA's certification:AWT

This series includes the following 50 minute sessions.Session 1: Developing Engineering Design Criteria for Partial Denitrification Anammox (PdNA) Implementation for Multiple Biofilm MediaPartial denitrification anammox (PdNA) implementation can combat some of the most difficult challenges facing California’s water resource recovery facilities (WRRFs). PdNA can alleviate strains caused by population growth and nutrients, while offering long-term budgetary benefits. Rather than using traditional nitrification and denitrification, PdNA can be implemented which has lower energy requirements, carbon demands, and greenhouse gas emissions. In PdNA, nitrate is reduced to nitrite (partial denitrification), and the reduction of nitrite to nitrogen gas (full denitrification) is avoided. The nitrite produced from partial denitrification can then be reduced to nitrogen gas with influent ammonium via anammox. This process has been proven to be more stable than alternative methods (partial nitritation anammox [PNA]), making it an attractive option for mainstream wastewater treatment.
This presentation will provide an overview of a $4 million U.S. Department of Energy (DOE) PdNA study that will implement PdNA in six WRRFs nationwide. The study focuses on determining engineering design criteria as nitrogen loading and removal rates, mixing requirements, headloss, fill ratios, and retrofittability of different media (moving integrated fixed-film activated sludge [IFAS], fixed IFAS, and biological aerated filters [BAFs]) to enable widespread PdNA implementation.
Applicability to California Utilities:
PdNA implementation can be a beneficial solution for California utilities that are seeking to increase capacity or are considering the initiation of a water reuse program. The capacity enhancement holds particular significance for facilities with footprint limitations, as PdNA can be retrofit into existing facilities without significant construction. From the perspective of water reuse, tertiary PdNA in a BAF offers a solution for achieving effluent total inorganic nitrogen (TIN) and total suspended solids (TSS) limits while minimizing modifications to upstream infrastructure.As a part of the DOE study, a pilot-scale tertiary BAF PdNA process will be evaluated at the Linda County Water District water resource recovery facility (WRRF) which should commence in Fall 2024. Startup and preliminary results from this pilot and other WRRFs will be shared at the conference.
Conclusion:
PdNA represents a cost-effective method for expanding capacity, reducing operation and maintenance costs, and transitioning to water reuse, making it a valuable solution for California utilities.
Learning Objectives:
Describe the overall benefits of PdNA, list several approaches to configure/implement PdNA, status of PdNA design criteria, and demonstrate innovative methods for overcoming headloss challenges associated with its implementation.
Identify the synergistic benefits of combining water reuse with PdNA and describe the tertiary BAF PdNA study at the Linda County WRRF.
Determine novel technologies that can potentially be integrated with PdNA to minimize the need for supplemental carbon."Session 2: A Flexible Future - How Split Flow BNR Opens Doors to Future Possibilities

In a recent project funded by California Energy Commission (CEC), an innovative thickening process -Suspended Air Flotation (SAF®)- was selected to be tested at demonstration scale. SAF® process presents a compelling alternative to traditional thickening methods considering its potential to reduce energy consumption and to separate emerging contaminants such as Per- and polyfluoroalkyl substances (PFAS).The SAF technique employs a suspension of micron-sized air bubbles, ranging from 7 to 50 µm, in water to attain a volumetric air content of 40 to 50%. These bubbles are coated with a thin layer of soap film derived from an electrically charged anionic or cationic surfactant. The charged bubbles offer a substantial interfacial area for the adsorption of oppositely charged flocculated wastewater solids. In practice, suspensions of charged bubbles are introduced into the flotation tank to interact with wastewater solids. The solids then ascend to the surface and are skimmed off. The clarified effluent is recirculated to the headworks.
SAF enhances traditional thickening methods like Dissolved Air Flotation (DAF) by eliminating the need for dissolved air, thus obviating the requirement for pressurization systems, recirculation pumps, compressors, and airlines, leading to considerable energy savings. SAF's capability to manage high solids loads also results in substantial footprint and power savings, high solids recovery (up to 99%), and a high solids loading rate (up to 40 lb/ft2/hr). Moreover, no polymer is needed to thicken sludge to 4% solids. Owing to these benefits, adopting SAF technology can lead to an energy savings of up to 90% compared to its conventional counterparts, such as DAF.
This presentation will assess this novel technology, its performance, present results from case studies, and elaborate on the potential of this technology for PFAS separation.
Learning Objectives:
Define the suspended air flotation technology (SAF) and difference between dissolved air flotation (DAF) technology
Demonstrate the advancements of SAF technology for various case studies including thickening of Advanced primary treatment solids and secondary solids
List the important criteria for the design and operational challenges of the SAF technology"Session 2: Anaerobic Digestion of Organics: Industry Drivers Overview of Two Case Studies for CHP and RNG
This presentation will discuss the diversion of organics, such as food waste and the co-digestion of these wastes with anaerobic digestion which generated biogas, a beneficial byproduct. Doing so allows reduction in landfill volumes and stabilization of the waste suitable for land application. The stabilization process, when accomplished with anaerobic digestion, generates biogas, a beneficial byproduct.The presentation will include an overview of industry trends, including regional trends in State of California for organics diversion requirements. Other industry drivers that will be covered will include greenhouse gas emissions reductions, state and federal financial incentives, and drivers for renewable energy production.
When organic waste is diverted to a wastewater treatment facility, the organics can be co-mingled with municipally generated sludge in anaerobic digestion (i.e., co-digestion). This allows for existing infrastructure to be utilized for both wastewater treatment and landfill diversion while generating a biosolids product and digester gas. The produced biogas can be utilized as a fuel source for a process heating boiler or in a combined heat and power system or renewable natural gas.
Finally, the presentation will include case study overviews of two functioning wastewater treatment facilities with anaerobic digestion, both which are receiving significant quantities of organic wastes to generate biogas from co-digestion. One facility is utilizing biogas produced in a combined heat & power (CHP) for use at the facility and has achieved net zero operations beginning in 2022. The second facility facility has a very large high strength waste program with over 19,000 loads received annually. The biogas from this facility is processing the biogas into renewable natural gas (RNG) for pipeline injection which generates over $6M annually.
Learning Objectives:
1. Gain understanding of the industry drivers for organics diversion and resource recovery programs.
2. Learn about two functioning full-scale wastewater treatment facilities with anaerobic digestion, both which are receiving significant quantities of organic wastes to generate biogas from co-digestion.
3. Define the concept the organics diversion, such as food waste and the co-digestion of these wastes with anaerobic digestion which generated biogas and potential value of this renewable fuel."Session 3: Resilient Resource Recovery at the Encina Water Pollution Control Facility
Encina Wastewater Authority's plan for resilient resource recovery at the Encina Water Pollution Control Facility will be presented. The plan focusses on having a reliable energy supply to treat wastewater and recover biosolids and energy for beneficial use. Having adequate anaerobic digestion capacity and enhancing its performance for more biogas is an integral part of the plan. Converting solids to biogas decreases the amount of biosolids sent to the dryer and reduces its energy demand. Using biogas to fuel combined heat and power (CHP) units and/or producing renewable natural gas (RNG) while complying with increasingly stringent air permit regulations will be discussed. Ultra-low emissions CHP units being considered include non-combustion fuel cells and flameless-combustion linear generators. The microbial hydrolysis process (MHP) using the hyper-thermophilic bacteria caldicellulosiruptor bescii will enhance the anaerobic digestion project to convert cellulose into biogas. Recuperative thickening will increase the capacity of the existing digesters by increasing the solids retention time (SRT). The reduction in solids concentration in the digesters because of the increased volatile solids reduction (VSR) from the addition of the MHP will balance the increase in solids concentration from the operation of recuperative thickening. The resulting solids concentration will be low enough to enable effective mixing with the existing digester mixing system. The enhanced anaerobic digestion system will produce more biogas and less biosolids. Producing more biogas and fueling ultra-low emission CHP units will contribute to energy resiliency by decreasing the dependence on utility supplied natural gas and electricity.Learning Objectives:
Upon completion, participants will be able to list the components in a resilient water resource recovery facility.
Upon completion, participants will be able to describe how anaerobic digestion is an integral part of resilient resource recovery.
Upon completion, participants will be able to define the microbial hydrolysis process and explain how it enhances anaerobic digestion."Session 4: Maximizing Biosolids Value: Post-Upgrade Optimization and Market Development
This presentation explores the optimization of new solids handling facilities and the creation of marketable biosolids products, drawing insights from two major utilities: Hampton Roads Sanitation District (HRSD) and JEA.HRSD’s Atlantic Treatment Plant (ATP) transitioned from Class B to Class A biosolids production by commissioning a Cambi thermal hydrolysis process (THP) skid in mid-2020. This transition resulted in increased solids capacity and improved final dewatering performance. The presentation will delve into the startup and optimization process, highlighting lessons learned and how these upgrades have prepared HRSD to adapt to future regulatory changes.
Initial startup required ATP to disinfect digesters and all associated piping. The first digester was filled with heated disinfected non-potable water and seed from DC Water’s digesters. The approach to ramping up thermally hydrolyzed sludge feed started at 50% of DC Water’s loading rate and increased over several weeks.
Using existing dewatering centrifuges, the final dewatering cake solids improved from 14-16% total solids (TS) to 30% TS after THP implementation and optimization. Curing pilots using the 30% cake and a windrow turner determined the most efficient method for producing a low-odor, aerobically cured product. Lessons from 2023 pilot studies have been applied to full-scale curing operations initiated in early 2024.JEA, one of Florida’s largest utilities, has proactively planned for the future of their biosolids program. In 2017, JEA’s master plan recommended decommissioning the old thermal drying system and outsourcing Class B dewatered cake processing to a third-party. However, this dependence led to uncertainties in costs and regulatory compliance.
In 2020, JEA revised their strategy, recommending a new regional biosolids handling facility at the Buckman Water Reclamation Facility (BWRF). This facility, designed to handle solids from all 12 JEA-owned water reclamation facilities, includes advanced thickening and dewatering equipment, two large thermal drum drying systems, and infrastructure for high-quality pellet production. These upgrades provide JEA with the flexibility to pivot as regulatory drivers change and new market opportunities arise.
The presentation will discuss innovative strategies employed by JEA, including a pilot of an in-line high-shear dynamic mixer to re-wet dewatered cake solids, reducing transportation costs and capital expenses.
Learning Objectives:
Describe the startup and optimization process of thermal hydrolysis and its impact on biosolids capacity and quality.
Explain approaches to evaluating and upgrading biosolids handling facilities, focusing on infrastructure, process reliability, and market development.
Identify key lessons learned in the production and market development for biosolids products."$i++ ?>

CWEA Contact Hours: 1.0 contact hours towards CWEA Certifications: AWTPresentation Description: Water reclamation facilities are facing a variety of new challenges, including the move toward potable reuse and new regulations to limit nitrogen discharges. This presentation explores the interactions between secondary effluent quality, potable reuse, and nitrogen removal.
Successful potable reuse requires high-quality, consistent secondary effluent. The first part of this presentation will discuss typical advanced treatment trains for potable reuse and identify the critical design parameters impacted by the secondary treatment processes. Key differences between secondary treatment types will be quantified. The evaluation documents higher concentrations and higher variability in non-nitrifying facilities for several key parameters for potable reuse design, including total organic carbon (TOC), ammonia, and nitrite. For non-nitrifying plants, average TOCs ranged from 14 to 27 mg-N/L; nitrifying plants averaged 10 mg-N/L or less. Some non-nitrifying plants routinely reported nitrite concentrations above 2 mg-N/L, and even the fully nitrified facilities occasionally reported nitrite concentrations above 1 mg-N/L and ammonia concentrations above 2 mg-N/L. Plants considering potable reuse should begin monitoring TOC and nitrite to provide data for advanced treatment design. Optimization or upgrades to secondary treatment may be necessary, depending on the advanced treatment goals and requirements. The presentation will help planners and designers understand the suitability and challenges of their secondary effluent for potable reuse.
Plants with new nitrogen limits are considering multi-benefit solutions incorporating recycled water and potable reuse to reduce nitrogen discharges. The second part of this presentation will discuss the impact of potable reuse on nitrogen discharges. A variety of upgrade scenarios for a conventional BOD-removal only plant upgrading to potable reuse will be considered, and the impact on nitrogen removal will be quantified. Scenarios considered include different secondary treatment types (conventional BOD-removal like trickling filter solids contact and nitrification/denitrification in activated sludge), different management of reverse osmosis concentrate (discharge of concentrate, return of concentrate to the plant influent, and separate treatment of concentrate), and a range of potable reuse flows. Although each plant situation is unique, the results will help planners and designers understand the feasibility of using potable reuse to reduce nitrogen discharges and the key factors that impact nitrogen discharges.
Learning Objectives:
Upon completion, participants will be able to list three secondary effluent quality parameters key to potable reuse design.
Upon completion, participants will be able to describe the suitability and challenges of their secondary effluent for potable reuse.
Upon completion, participants will be able to understand the key potable reuse design decisions that impact nitrogen discharges."$i++ ?>

CWEA Contact Hours: 1.0 contact hours towards CWEA Certifications: AWTPresentation Description: California DPR Regulations require ozone and biological active carbon (BAC) filtration ahead of full advanced treatment consisting of reverse osmosis (RO) and advanced oxidation process (AOP). The main purpose of ozone and BAC is to address low molecular weight organic compounds some of which such as acetone, formaldehyde cannot be effectively removed by the full advanced treatment. The other purpose of ozone-BAC is to provide an additional barrier for chemical peak “averaging”.
While Ozone-BAC can provide an effective barrier for low molecular weight compounds that are poorly removed by full advanced treatment, the capabilities of ozone-BAC is limited to relatively small chemical peaking based on North City chemical spike studies. However, one critical area has not come to closer attention of State Water Board. That is the secondary treatment. In this presentation, we will explain inevitable role of secondary treatment in a DPR train. First, an activated sludge based secondary treatment can provide excellent removal for slowly biodegradable organic compounds such as acetone, formaldehyde and all other low molecular alcohols and ketones that are poorly removed by full advanced treatment. Second, a secondary treatment can provide nitrogen control which is critical to meet nitrite and nitrate nitrogen primary MCLs of 1 and 10 mg/L, respectively. These limits may not be reliably met in RO-based full advanced treatment if no nitrogen control is provided in the upstream wastewater treatment plant (e.g., Hyperion WRP).
Third, a good nitrogen control is essential to minimize secondary effluent nitrite concentration which creates very high ozone demand during ozonation. Last but not least, a well-designed and operated secondary treatment can provide a high-quality effluent with reduced suspended solids, phosphate and metals which can create operational challenges at downstream advanced water purification facility (AWPF).
In summary, how a robust secondary treatment along with performance requirements make DPR possible and case study examples will be presented to demonstrate how secondary process performance affects & defines AWPF design, performance & operation in a DPR train. It will provide an unmatched value for public and regulatory agencies to explore how secondary treatment that makes DPR projects more robust and resilient.
Learning Objectives:
To understand capabilities and limitations of ozone and BAC for chemical control in DPR projects
To understand role and superior benefits of activated sludge based secondary treatment in DPR
To understand how we can configure secondary treatment to make DPR projects more robust and resilient"$i++ ?>Zeynep Erdal

CWEA Contact Hours: 1.0 contact hours towards CWEA Certifications: AWTPathogen control and monitoring in water reuse applications is critical to public health protection and gaining public trust. As more utilities and water agencies consider implementing water reuse programs, obtaining credit for log reduction values (LRV) achieved through secondary and tertiary wastewater treatment processes will be an important consideration. While many utilities exploring reuse options are currently focused on membrane processes to achieve additional virus log removal credits, questions remain regarding LRV achieved through various conventional treatment trains. In addition, while molecular assays exist for the detection of viruses, the majority of these methods provide no information on culturability or infectivity thus making extrapolation of end-user exposure risk and identification of suitable applications challenging. The objective of this study was to assess the removal of human infective viruses throughout the stages of wastewater treatment in a full-scale, tertiary municipal wastewater treatment plant in Canada.
The plant resells 20% of its secondary effluent to an industrial partner after additional treatment by membrane filtration and chlorination. The remaining 80% of the secondary effluent undergoes UV disinfection prior to release into the environment. The partnership between the plant and the industrial partner produces 15 million liters of high-quality water for processing each day, which are used in the refinery cooling tower, boiler and hydrogen plant. Virus concentrations and infectivity were analysed using real-time quantitative PCR (qPCR) and integrated cell culture (ICC) to identify infective human viruses. Seven viruses including Norovirus (NoV), Rotavirus (RV), Sapovirus (SaV), Astrovirus (AsV), Adenovirus (AdV), Enterovirus (EV) and JC virus (JCV) were detected in 16 primary effluent samples in which infective viruses were present. Different treatment steps showed various efficiencies in infective virus removal, with membrane filtration exhibiting the highest at 4.6–7.0 log reductions.
The overall treatment virus LRV ranged from 1.1 (RV) to 2.8 (EV) for UV-treated final effluent and from 4.6 (EV) to 7.0 (AdV) when membrane filtration and chlorination were applied. The LRV for the six viruses (except for EV) by membrane filtration were significantly greater than that obtained by UV. EV had the highest inactivation by UV but the lowest by membrane filtration.
Learning Objectives:
After the presentation, participants will be able to articulate the benefits and limitations of different viral testing methods and the potential value that coliphage testing might add.
After the presentation, particpants will be able to compare the removal of viruses after various treatment steps.
After the presentation, particpants will have more data to highlight the value and potential virus log removal credits that can be achieved by ultrafiltration (6–7 LRV)."$i++ ?>

CWEA Contact Hours: 1.0 contact hours towards CWEA Certifications: ECIPresentation Description: In a recent project funded by California Energy Commission (CEC), an innovative thickening process -Suspended Air Flotation (SAF®)- was selected to be tested at demonstration scale. SAF® process presents a compelling alternative to traditional thickening methods considering its potential to reduce energy consumption and to separate emerging contaminants such as Per- and polyfluoroalkyl substances (PFAS).
The SAF technique employs a suspension of micron-sized air bubbles, ranging from 7 to 50 µm, in water to attain a volumetric air content of 40 to 50%. These bubbles are coated with a thin layer of soap film derived from an electrically charged anionic or cationic surfactant. The charged bubbles offer a substantial interfacial area for the adsorption of oppositely charged flocculated wastewater solids. In practice, suspensions of charged bubbles are introduced into the flotation tank to interact with wastewater solids. The solids then ascend to the surface and are skimmed off. The clarified effluent is recirculated to the headworks.
SAF enhances traditional thickening methods like Dissolved Air Flotation (DAF) by eliminating the need for dissolved air, thus obviating the requirement for pressurization systems, recirculation pumps, compressors, and airlines, leading to considerable energy savings. SAF's capability to manage high solids loads also results in substantial footprint and power savings, high solids recovery (up to 99%), and a high solids loading rate (up to 40 lb/ft2/hr). Moreover, no polymer is needed to thicken sludge to 4% solids. Owing to these benefits, adopting SAF technology can lead to an energy savings of up to 90% compared to its conventional counterparts, such as DAF.
This presentation will assess this novel technology, its performance, present results from case studies, and elaborate on the potential of this technology for PFAS separation.
Learning Objectives:
Define the suspended air flotation technology (SAF) and difference between dissolved air flotation (DAF) technology
Demonstrate the advancements of SAF technology for various case studies including thickening of Advanced primary treatment solids and secondary solids

CWEA Contact Hours: 1.0 contact hours towards CWEA Certifications: LAB, AWTOGrowing concerns associated with contaminants of emerging concerns (CECs) (especially PFAS), greenhouse gas emissions, and regulations have begun to limit the end-use alternatives for biosolids. In response to these pressures, biosolids producers are considering new and innovative treatment options that require a new perspective to the historical understanding of biosolids treatment and end-use. Orange County Sanitation District (OC San) has embarked to seek a new technology, Supercritical Water Oxidation (SCWO) to diversify their end products from water reclamation facilities (WRRFs). OC San teamed with 374Water that is collaborated Hazen and Sawyer, and Merrell Brothers to demonstrate this technology at their site. SCWO is a promising technology that converts organic material (biosolids) to inert gases, minerals and water. Water above 374°C and 22.1 MPa becomes supercritical, a special state where organic solubility increases, and oxidation processes are accelerated.
SCWO has been recently shown to destroy hazardous substances such as halogenated compounds including poly-fluoroalkyl substances (PFAS). Studies showed a greater than 99% reduction of the total PFAS identified in a targeted compound analysis, including perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) (Krause et al, 2022). As a destructive technology, SCWO is proposed as an alternative to incineration and other combustion processes and could be a permanent solution for PFAS-laden biosolids or solid matrices. However, additional investigation of reaction byproducts: water, solids and air emissions need to be conducted for a complete assessment of SCWO’s potential as a safe and effective technology.
OC San is located in South Coast Air Quality Management District (SCAQMD) and an air permit is required for this demonstration project. The research team, including OC San (a Utility), 374Water (a private firm-technology provider), Hazen and Sawyer (a consulting firm), Yorke Engineering (permitting support), Alliance Testing (a source testing firm) worked together to develop a rigorous test plan and granted a research permit to implement SCWO at Plant 1. This presentation will focus on the technology and design details, and provide the steps taken to implement this technology at OC San. The information will benefit utilities that seeks sustainable solution for their biosolids management considering recent end-use restrictions."Learning Objectives:
Define supercritical water oxidation process and list the advantages/disadvantages of this innovative technology
Describe the steps to take to implement SCWO
Identify the testing necessary to permit SCWO facility."$i++ ?>Mohammad Abu-Orf

AC24 Conference and Expo; Mission: Possible - A Sustainable Water Future Against All Odds. April 9-12, Sacramento
Cost: Complimentary
No Contact Hours OfferedIn California WRRFs are facing uncertainty with their current land application programs related to anticipated PFAS regulations. In addition, with the diversion of organics from landfills by SB 1383 the main strategy is co-digestion followed by composting to produce a Class A biosolids for beneficial use. However, with the emerging challenges related to PFAS, the composting part of this strategy may be impacted as it does not provide any PFAS treatment. On the other hand, drying produces Class A biosolids and is required upstream of advanced thermal processes for PFAS treatment including pyrolysis and gasification. Drying the dewatered digestate rather than composting provides an opportunity to limit the impacts of anticipated PFAS biosolids regulations.
This presentation will cover three thermal drying case studies that will benefit utility managers, operation and maintenance practitioners, and engineers by providing:
• a highlight of the thermal drying sizing, technology selection, and dried product characteristics,
• system integration with existing WRRFs including sludge conditioning,
• the lessons learned including equipment procurement, staffing, and challenges in operation from previous thermal drying designs., and
• integration insights for future pyrolysis/gasification PFAS treatment.Attendee Takeaways:
Conduct thermal drying sizing, technology selection, and describe the dried product characteristics.
Understand system integration with existing and future solids treatment.
Define project delivery and operations based upon lessons learned from thermal drying case studies."$i++ ?>

CWEA Contact Hours: 1.0 contact hours towards CWEA Certifications: LAB, AWTOThis presentation will review the cost to manage biosolids in various New England states, and the impact that PFAS has had on utilities’ operating budgets and operations for biosolids management. Maine’s land application moratorium, signed by the governor, will be discussed, including its short- and long-term impacts. The reactions of nearby states such as New Hampshire, Vermont, and Massachusetts’s to EPA’s PFAS roadmap; Maine’s moratorium; and growing negative public perception will be reviewed such that California agencies can learn from New England utilities’ experiences. We will also review successes in these states, where progress has been made working with regulators, communities, activist groups, and local legislative bodies.
EPA currently has not set any policies on PFAS in NPDES permitting, nor PFAS in biosolids. However, CERCLA has recently proposed designation of PFOS and PFOA as hazardous materials, which could impact water reclamation facilities and potential liabilities. States are taking matters into their own hands, ranging from a “do-nothing” approach to instituting a statewide ban on the land application of biosolids (Maine) which has severely disrupted biosolids management . Many states are moving toward “report only” requirements in NPDES permits for influent, effluent, and biosolids to increase the database of PFAS in the environment.
What should California do? To date, most states have not imposed PFAS standards in NPDES permits or biosolids, but Michigan’s EGLE has done precedent-setting work on PFAS in WW and mitigating sources. Utilities and consultants need to be prepared to educate communities, the legislature, regulators, and other stakeholders on the direct and indirect impacts of regulations and legislation around PFAS and water reclamation facilities. Industries discharging to WRFs need to participate in the conversation and become part of the solution through source control. In parallel, the science needs to continue to be developed and expanded, to better understand the true health and environmental implications of these compounds. This presentation aims to continue the conversation and information sharing so measured and thoughtful actions can be taken to address this issue in a fiscally and environmentally responsible manner, and so Californians can benefit from and implement the best practices.
Attendee Takeaways:
Understand the value of biosoli.
Understand the value of biosolids to our communities and impact of PFAS regulations.
Success ways to communicate with regulators, legislature and other key stakeholders.
Understand the state of the science and current understanding of PFAS in Biosolids.ds to our communities and impact of PFAS regulations."$i++ ?>Eric Spargimino (he/him/his)

CWEA Contact Hours: 1.0 contact hours towards CWEA Certifications: ECI,LAB, AWTOAs more WRRFs in California implement potable reuse schemes, and the impact of nutrients on coastal waters is recognized, biological nitrogen removal is expected to expand dramatically along the coast. Upgrading to nitrogen removal can significantly increase the cost, energy use, operational complexity, footprint requirement and climate impact of these facilities, and so determining the most efficient and sustainable treatment strategy is critical. Anammox is a unique biology that has been widely implemented in sidestream treatment to reduce costs and improve sustainability and efficiency, but this technology has not yet been implemented widely in mainstream secondary trains. This presentation will review two new technological developments that promise to bring the benefits of Anammox biology to mainstream secondary treatment.
First, we will describe the challenge of adapting the partial-nitration/Anammox process (PN/A) from hot, concentrated centrate treatment to dilute, cool secondary treatment. This strategy boasts the highest potential reductions in aeration energy, carbon requirements and sludge production, but is also the most challenging to operate and maintain. Challenges associated with NOB inhibition will be discussed, and a novel strategy, developed by Tomorrow Water and demonstrated with Black & Veatch at the Hyperion Water Recovery Plant in LA, will be described. We will share data from lab and pilot-scale facilities, highlighting the newest developments in process design and the relationship of critical control variables (inhibition frequency, temperature, nitrogen species ratio, etc.) We will also discuss the knowledge gaps that remain in order to bring this novel strategy into wide implementation.
Secondly, we will describe an alternative strategy for mainstream Anammox implementation: partial denitrification/Anammox (PdN/A). This strategy was developed in plants in the mid-Atlantic, and is now being commercialized for deployment in California (and worldwide). The process uses the same Anammox biology, but in concert with different supporting organisms (heterotrophic denitrifiers instead of ammonia-oxidizing bacteria.) This presentation will compare PN/A and PdN/A strategies, explaining the differences in process design, control, and achievable efficiency gains between the two different strategies. Participants will be provided with hypothetical plant scenarios and polled to determine which of the two strategies would be more applicable in a given context
Learning Objectives:
Quantify the benefits of the mainstream anammox process in terms of energy, carbon requirements, sludge production and plant intensification.
Differentiate between the two distinct implementation strategies of mainstream anammox (PN/A vs PdN/A) and understand their comparative advantages and challenges
Describe a novel PN/A strategy piloted at Hyperion WRP, and how this strategy fits in to the larger industry effort to commercialize mainstream PN/A for improved plant efficiency and sustainability$i++ ?>Jon Liberzon
