Abstract
Methods and systems of PFAS destruction including recovery and recycling of reactants. The method may include combining water including PFAS with fresh reactants including photosensitizer, sulfite salt and base to form an initial treatment solution having a pH of about 10 or more, irradiating the initial treatment solution with UV light in a photoreactor to destroy a portion of the PFAS and form treatment effluent, passing the treatment effluent through an ion selective membrane, combining the reject solution with water including PFAS to form a subsequent treatment solution, irradiating the subsequent treatment solution with UV light in the photoreactor to destroy a portion of the PFAS and form a treatment effluent, and repeating the process to recycle the recovered reactants one or more additional times. After the recovered reactants are recycled multiple times, they may be purged.
