Choosing an effective PFAS water treatment strategy is one of the most consequential near‑term decisions municipal utilities face as regulations tighten and short‑chain chemistries complicate removal. This guide compares GAC, ion exchange, RO/NF, and emerging destruction options and provides the design parameters, monitoring and residuals management practices, cost drivers, and a pilot-to-implementation roadmap municipal decision […]
Introduction As municipal and industrial treatment plants face increasingly stringent regulatory limits for PFAS, microplastics, heavy metals, and trace pharmaceuticals, engineers are discovering the limitations of conventional polymeric membranes and granular activated carbon (GAC). To achieve higher permselectivity while reducing the severe energy penalties of high-pressure reverse osmosis (RO), plant designers must look to the […]
INTRODUCTION The promulgation of stringent regulatory limits—including the EPA’s National Primary Drinking Water Regulation (NPDWR) setting Maximum Contaminant Levels (MCLs) for PFOA and PFOS at an unprecedented 4.0 parts per trillion (ppt)—has fundamentally shifted the landscape of municipal and industrial water treatment. For engineers, treating per- and polyfluoroalkyl substances as a monolithic contaminant class is […]
