What Utilities Don't Know About GAC Reuse For PFAS For utilities building PFAS treatment systems, thermal reactivation of spent granular activated carbon (GAC) may sound like the obvious answer. However, service provider availability and location, specific media acceptance criteria including quantity thresholds, restrictions on GAC type and condition, and regulatory uncertainty can all determine whether reuse is a viable option. -

PFAS Funding Is Flowing — But Does The Water Sector Have Enough People To Deliver It? For several years, the PFAS conversation has centered on treatment options, testing, and funding. Those factors still matter, but they are no longer the primary constraint. Most utilities already understand the treatment routes available to them; the real challenge now is moving from technical possibility to operational performance, and that depends entirely on people. -

D.C. Circuit Upholds EPA's Hazardous Substance Designation For PFOA, PFOSThe U.S. Court of Appeals for the D.C. Circuit recently rejected industry challenges to the EPA's designation of PFOA and PFOS as hazardous substances under CERCLA, leaving the agency's April 2024 rule fully intact. While the case centered on the EPA's authority to make the designation, its practical significance for water utilities is simpler: the liability concerns that have accompanied the rule since its adoption remain unresolved.

The Enzyme Bottleneck: Why Conventional Lake Management Is Failing — And What The Science Says About Genuine Bio-Dredging For decades, the dominant framework for assessing and managing lake health has been built around surface water measurements: chlorophyll-a, total phosphorus, water clarity, and the composite Trophic State Index derived from them. These metrics are familiar, standardized, and widely accepted. They are also, according to a growing body of peer-reviewed literature, measuring the wrong part of the lake. -

Surface water contamination demands advanced treatment solutions. Learn how UV advanced oxidation simultaneously destroys complex micropollutants and inactivates pathogens in a single step, offering a scalable, cost-effective alternative that eliminates chemical residuals and reduces seasonal operating expenses.
Ozone treatment for water and wastewater has been utilized successfully for several decades and continues to be a viable disinfection solution for both municipal and industrial plants, worldwide.
Coal-fired power plants generate coal fines and coal ash from a number of sources, including coal combustion residuals (CCR), particularly fly and bottom ash from coal furnaces, and coal pile runoff during rain events. In support of an industry-wide effort to reduce, improve, and remove coal ash ponds, a variety of technologies have been tested and employed. Read the full application note to learn more.
The DE NORA TETRA® ABF bioactive filter combines ozone generation with biologically active filtration for use in municipal water applications. The process targets micropollutant reduction and reduces disinfection byproducts in drinking water and potable reuse applications.
The highly scalable newterra WWT-50 Sewage Treatment Mini Train System is designed for rapid mobilization to serve camps of 200 to 800 people. These efficient plants are configured in trains that allow modular expansion and easy redeployment of assets. Each base configuration consists of two 40' containers that provide 50 m3 (13,200 US gal) of treatment capacity – enough for 200 people. Supplementing the base system with one 40' Adder container doubles capacity to 100 m3 for up to 400 people.
