Much research has been devoted to developing advanced oxidation technologies for destroying hazardous chemical wastes. The fundamental chemistry behind these processes has been studied extensively and is reasonably well understood; however, their scale-up from the bench to the pilot plant or field test is not a trivial exercise. Major engineering challenges exist in designing nonthermal industrial oxidation technologies that are cost-effective, robust, and versatile. One possible approach is to use existing technologies that have proven to be successful in industrial applications. The electrohydraulic discharge (EHD) method is a non-thermal process based on pulsed-power technology. EHD injects energy into an aqueous solution through a plasma channel formed by a high-current/high-voltage electrical discharge between two submersed electrodes. The paper describes system design, degradation experiments to elucidate the oxidation kinetics, EHD-ozone experiments, and energy efficiency.
