Understanding and Addressing PFAS in Metal Finishing
White Paper
This white paper explores the growing impact of PFAS regulation on the metal finishing industry and outlines practical steps for facilities seeking to understand, detect, and reduce PFAS in their wastewater. It traces the historical use of PFAS-based mist suppressants, presents findings from a nationwide wastewater study conducted with FREDsense, and compares the effectiveness of common treatment methods. With carbon filtration emerging as the most economical option for meaningful PFAS reduction, the paper highlights upcoming research and recommends that finishers evaluate their waste streams, benchmark PFAS levels, and plan proactively for evolving regulatory requirements.
