Methods and systems for continuous PFAS destruction

Abstract

Methods, systems and devices for lowering a concentration of a PFAS in a solution including exposing a treatment solution to a UV light source from one or more lamps in a continuous reactor, the treatment solution comprising a PFAS, an inorganic ion, and having a pH of about 8 or more, and flowing the treatment solution through the continuous reactor at a flow rate of equal to or greater than 5 gallons per minute while exposing the treatment solution to the UV light. The treatment solution to UV light in the continuous reactor results in partially or fully defluorinating about 80% or more of the PFAS in the treatment solution.
