A Synergistic Platform for Defluorination of Perfluoroalkyl Acids (PFAAs) Through Catalytic Reduction Followed by Microbial Oxidation

Abstract

Perfluorodoctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) are widespread and persistent water contaminants of great concern today. In our synergistic platform, two membrane film reactors are linked by sending the effluent of an H2-based membrane catalyst film reactor (MCfR) to be the influent of an O2based membrane biofilm reactor (MBfR). PFOA/S is reductively defluorinated in the H2MCfR to less fluorinated or nonfluorinated species. The less fluorinated species are transferred to the O2MBfR, where they are further defluorinated and ultimately mineralized.
