Claim 11:
12. A method of destroying PFAS, comprising:, providing an aqueous solution comprising water and PFAS;
treating the aqueous solution to reduce its volume to form a reduced volume PFAS solution having a first concentration of PFAS;
adding hydrogen peroxide to the reduced volume PFAS solution wherein the hydrogen peroxide is added in excess of that needed to destroy the PFAS;
passing the reduced volume PFAS solution into a SCWO reactor and subjecting the reduced volume PFAS solution to supercritical water oxidation; and
producing a clean effluent having a concentration of PFAS that is more than 100,000 times less than the first concentration of PFAS; and wherein the reduced volume PFAS solution is mixed with a solution comprising 30 to 50 wt % H2O2 at a weight ratio of between 30:1 and 70:1 wt % PFAS solution.
