Pilot Scale Assessment of a Deployable Photocatalytic Treatment System Modified with BiPO4 Catalyst Particles for PFAS Destruction in Investigation-Derived Wastewaters
Abstract
The BOHP/UV photocatalytic advanced oxidation process was developed at Clemson and previously shown via bench testing to rapidly mineralize PFOA in pure waters. The objectives of this limited scope project were to assess the capabilities of the treatment method for a wider range of PFAS contaminants relevant to IDW, identify important complex water matrix considerations and quenching species, and demonstrate performance of the catalyst upon incorporation into a deployable commercial photoreactor system. Furthermore, BOHP's lack of activity toward PFSAs warranted pursuit of a complimentary photocatalytic process to address this important subclass of PFAS contaminants. Photocatalytic reduction of PFOS by BiPO4 and GaOOH semiconductor particles was thus examined through bench experiments and one pilot test.
