Abstract
A process for electrochemically treating an aqueous solution containing inorganic oxyhalide species is disclosed in which the aqueous solution is fed into the catholyte compartment of an electrochemical reduction cell using a high surface area cathode separated from an anolyte compartment to electrochemically reduce substantially all of the oxyhalide species to halide ions and produce a purified water product.
