Tight membranes including reverse osmosis and nanofiltration are evaluated for per- and polyfluoroalkyl substance (PFAS) removal in drinking water applications following U.S. EPA National Primary Drinking Water Regulations for six PFAS compounds. Rejection mechanisms examined include size exclusion, electrochemical repulsion, and sorption interactions at the membrane surface. Key factors influencing PFAS rejection are analyzed including membrane type and chemistry, target compound molecular weight and ionic charge, pH, temperature, natural organic matter concentration, and divalent ion interactions, providing guidance for membrane selection in PFAS compliance programs.
