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 […]

Foam Fractionation for PFAS: A Comprehensive Solution for Contaminated Water Introduction The contamination of drinking water sources with per- and polyfluoroalkyl substances (PFAS) represents one of the most pressing environmental challenges of the 21st century. As municipalities and industries grapple with stringent regulations and public health concerns, finding efficient treatment methods has become paramount. Foam […]
