Pretreatment Systems Enable Complete And More Economical PFAS Solutions For operators looking to optimize their PFAS removal systems, controlling the presence of dissolved organic carbon (DOC) offers an approach to minimizing operational costs due to granular activated carbon (GAC) reactivation and ion exchange media change-out.
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.
The Cost Of Waiting: Utilities Face A Narrowing PFAS Compliance Window For years, the water industry's PFAS conversation centered on monitoring, testing, and regulatory anticipation. Today, that phase is largely over.
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.

TrojanUVFlex -- Water Reuse & Drinking Water Disinfection System

TrojanUVFlexAOP – Advanced Oxidation System

Meeting the demand for clean water has never been more challenging. Communities around the world are facing a growing water stress – an insufficient supply, in terms of water quality or water quantity – and often both. Many are turning to potable reuse and drinking water remediation to meet these demands. The TrojanUVFlex®AOP can be part of the solution. This UV advanced oxidation system destroys a range of chemical contaminants while simultaneously providing final treatment, helping municipalities relying on lower quality water sources to continue producing high-quality potable drinking water.

Why Should We Care About NSF/ANSI 61 Certification?

According to National Sanitation Foundation (NSF) and the American National Standards Institute (ANSI), it's a set of standards relating to water treatment and establishes criteria for the control of equipment that comes in contact with either potable water or products that support the production of water.
