Reuse water used for irrigation and aquifer recharging is especially beneficial in arid and semi-arid regions, but also in general to reduce dependency on other natural resources. In addition, reuse plays an important role in building sustainability and resilience in design and construction. Often overlooked aspect of recovery in municipal wastewater is water from sludge, which typically contains between 75 to 95% moisture. 

A private real estate investment firm in Texas is developing a reclaimed industrial site in Houston with a vision of creating a circular and sustainable waste management opportunity within the new development. The goal is to transform wastewater, food waste, and other recyclable wet organic wastes into recoverable and reusable clean water, energy, and nutrients. The technologies being considered for this approach include membrane bioreactor, supercritical water oxidation and ultraviolet light disinfectant. 
The combination of these technologies’ makeup the treatment scheme for this decentralized water reuse facility, which is being developed in partnership with 374Water, a global social impact, cleantech company that provides unique decentralized water resource recovery facilities. The challenge with a fixed treatment asset is maintaining consistency of wastewater feed. In other words, would the development produce the same or similar volume of waste, with uniform constituents, on a daily basis. 

One way to overcome this challenge and to maximize the beneficial use of the investment, the facility will employ sewer mining, a process where municipal wastewater from the pipeline, with consent from the City, will be drawn and used as a supplement waste to offset variation in waste generated from the development on a daily basis. Simply put, in order to stabilize the flow and feed characteristics of the waste to be treated, wastewater from the sewer will be drawn at a rate that brings the overall waste to the average treatability volume and quality for each of the technologies being employed. This webinar will cover the role of SCWO to transform waste inputs into usable byproducts.

The membrane aerated biofilm reactor (MABR) process is an emerging activated sludge intensification technology that has received much interest in the wastewater industry. MABRs include a biofilm with high concentrations of nitrifiers. The biofilm removes a portion of the influent ammonia, and sloughed biomass seeds the activated sludge process with nitrifiers. This allows the activated sludge process to be operated at a lower sludge retention time (SRT) which translates to more capacity. Capacity benefits are more significant in cold weather applications where long SRTs are typically needed for reliable nutrient removal. Given the limited full-scale operating experience, technology evaluation and design must rely on pilot and modeling results.

The Sanitation Districts recently conducted a successful MABR pilot (Mansell et al 2022); however, due to mechanical issues, the pilot could not be operated at low SRTs to confirm performance and capacity benefits. Due to the warm climate, steady-state modeling indicates that CAS can achieve similar nitrogen removal as MABRs at aerobic SRTs as low as 3 days. It also shows reliable MABR performance at aerobic SRTs as low as 2 days. Steady-state modeling typically predicts better performance than what is experienced with the day-to-day variability of real treatment plants. To better quantify the performance and capacity benefits of warm weather operation at low SRTs, year-long dynamic modeling simulations are performed over a range of operating conditions for CAS and MABR. Frequency distributions for effluent performance and nitrifying biomass are developed to establish target SRTs that achieve comparable performance, reliability, and risk for CAS and MABR processes. This evaluation will help support the Sanitation District’s decision-making for upgrades at LCWRP.

•         Learning Objectives/Attendee Takeaways: 
No. 1: MABR Technology for Capacity Enhancement: MABR technology intensifies activated sludge processes by efficiently removing ammonia and seeding activated sludge with nitrifiers, increasing capacity, especially in cold weather.
No. 2:  Evaluation at LCWRP: LCWRP is considering MABR for future capacity and treatment enhancement. Modeling suggests that MABRs can achieve similar nitrogen removal as conventional methods at lower SRTs in warm climates, with reliable performance.
No. 3: Dynamic Modeling for Decision Support: Dynamic modeling over a year-long period helps quantify performance and capacity benefits, aiding in establishing target SRTs for comparable performance and reliability between CAS and MABR processes. This supports decision-making for plant upgrades at LCWRP.

Wastewater collection systems in the USA boast approximately two million pump stations, serving as vital components of sewer agencies. However, these stations come with challenges. Balancing wastewater pumping costs with the prevention of septic conditions within wet wells is critical. Imbalance leads to excessive energy consumption or accelerated corrosion and infrastructure deterioration. Wet wells, primarily constructed from reinforced concrete, are particularly susceptible to corrosion from hydrogen sulfide produced by microbiological activity.

In Bullhead City, AZ, a lift station wet well of nearly 13,500 cubic feet faced corrosion issues due to sulfide attack. The city required a rehabilitation solution that would endure the structure's lifetime, restore lost structural integrity, and shield against corrosion. Thankfully, an innovative technology emerged—a revolutionary approach within the sanitary sewer industry. Structural panels pieced together to form a cohesive inner shell, made from inert materials were anchored, grouted, and sealed with epoxy resin. These panels, along with the grout, not only restored lost structural capacity but also provided comprehensive lining to shield the interior from the corrosive environment.

This highly customizable solution caters to nearly all large sanitary sewer structures in need of corrosion-resistant lining. Unlike some spray-applied liners, this method firmly anchors the solution to the walls, ensuring a one-and-done rehabilitation process that stands the test of time.

•         Learning Objectives/Attendee Takeaways: 
No. 1: Critical Challenges: Wastewater pump stations in the USA face the challenge of balancing pumping costs with preventing septic conditions in wet wells, which can lead to energy wastage and infrastructure corrosion, especially in wet wells made of reinforced concrete.
No. 2:  Case Study: Bullhead City, AZ: Bullhead City addressed corrosion in 13,500 cubic feet lift station wet well caused by sulfide attack. They implemented an innovative solution involving structural panels forming an inert inner shell, anchored, grouted, and sealed with epoxy resin.
No. 3: Revolutionary Rehabilitation: This approach not only restored structural integrity but also provided comprehensive lining to shield against corrosion. It represents a significant advancement in combating corrosion challenges in wastewater infrastructure, ensuring long-term performance.

7Habits of Effective Source Tracking
Per- and polyfluoroalkyl substances (PFAS) are ubiquitous, including detectable amounts typically in the parts per trillion (ppt) range in wastewater effluent and parts per billion (ppb) range in solids. The US EPA plans to publish ambient water quality human-health-based criteria for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) by Fall 2024. The EPA also plans to finalize their risk assessment for PFOA and PFOS in biosolids by Winter 2024.

Tracking down and mitigating these sources would be the first step in proactively minimizing or eliminating these chemicals and complying with upcoming regulatory provisions. Source control would be more cost-effective and environmentally just approach than treatment. This talk will discuss the risks to treatment plants in having to mitigate and comply with PFAS standards and outlines guidance that was developed as part of the Water Research Foundation (WRF) Project #5082: Investigation of Alternative Management Strategies to Prevent PFAS from Entering Drinking Water Supplies and Wastewater to help utilities track PFAS sources. 

In this webinar, attendees will learn the following: 

Identify appropriate lab methods for PFAS sampling.
Build a PFAS monitoring and source control plan for their wastewater utility.
