Abstract

This invention is directed to a method and apparatus for controlling and optimizing the feed of two or more oxidizers to an aqueous stream, thereby providing a synergistic effect. The combined use of amperometric or ORP based sensor technology with amperometric sensor technology employing a gas permeable membrane provides definitive control of each oxidizer feed stream.
