Abstract: A method and apparatus for treating dilute and micro concentrations of pollutants, particularly PFASs, in aqueous solutions. The apparatus including an electrode assembly including a working electrode, a counter electrode, and a cell divider positioned between the working electrode and counter electrode. The cell divider including an ion conducting membrane where the ion conducting membrane selectively conducts protons or hydroxyl anions but is an electronic insulator and a barrier to liquid, contaminant, and gas exchange.

Abstract: The invention of the current application is directed to a wastewater treatment apparatus. The invention includes a divided membrane electrochemical cell including an anode contained within a anode compartment and cathode contained within a cathode compartment. The anode compartment and said cathode compartment are separated by a proton selective membrane. The invention also includes a voltage source, and a liquid-gas separator. The invention is an economically viable electrochemical advanced oxidation system that can cost-effectively treat recalcitrant COD with low energy, without the necessity for chemicals, and reduce or prevent sludge production in a single step.
