Abstract

Per- and polyfluoroalkyl substances (PFAS) are a common contaminant inmunicipal landfill leachate and are recognized as a pollutant on global scale.The present work examined foam fractionation (FF) in batch and continuousmodes as an appropriate treatment technique for PFAS removal for the landfillleachate and found stable removal efficiency of greater than 90% for PFOA(C7), PFOS (C8), PFHxS (C6), and PFHpA (C6) and 6:2 FTSA (C6). For otherPFAS such as PFNA (C8), PFPeS (C4), PFHxA (C5), PFHpS (C7), and PFBS(C4), a less stable removal between 80% and 50% was achieved while between50% and 20% removal was observed for EtFOSAA (C8), PFBA (C3), PFDA (C9),FOSA (C8), PFPeA (C4), and MeFOSAA (C8). Increased air flowrate, additionof iron (III) oxide (Fe+3) coagulant, conductivity, and greater untreated leach-ate PFAS concentration were factors resulting in increased removal efficiencyfor the majority of PFAS.
