Abstract
Processes and apparatuses converting poly- and perfluoroalkyl substances (PFAS). An oxidation reaction zone, preferably a thermal oxidizer, is utilized to oxidize the PFAS into anionic fluoride species. A treatment zone is utilized on at least a portion of the oxidation zone effluent before the oxidation zone effluent is vented or otherwise released to the atmosphere. The treatment zone may include a dry sorbent injection zone; a selective catalytic reduction zone, a wet scrubber zone; a carbon bed; an ion exchange zone; or any combination thereof.
