Abstract:
The present invention relates to systems and methods for catalytic removal of per- and polyfluoroalkyl substances (PFAS) from water and wastewater. The system and methods utilize a catalyst film and a biofilm to synergystically remove PFAS from water. In some aspects, the catalyst film reduces and defluorinates PFAS into less fluorinated counterparts of PFAS, and the biofilm metabolizes the less fluroinated counterparts of PFAS into CO2 or shorter chain PFAS.
