Electrochemically-Induced In Situ Degradation of Legacy Munitions and Insensitive High Explosives in Manufacturing Wastewater

Abstract

To meet the need for improved, cost-effective water treatment technologies for both legacy and new insensitive high explosives in wastewater, the investigators have developed a two-reactor system containing a flow-through electrochemical reactor that generates reductants based on reactive electrode surfaces and electrolysis of water, followed by a flow-through column containing a nanosized manganese dioxide catalyst supported on granular activated carbon sorbent for conversion of injected hydrogen peroxide to hydroxyl radicals. The reactor units use low power, feature inexpensive stainless steel electrodes, and is capable of sustained, long-term operation without electrode degradation. The objective of this work is to optimize the electrochemical and sorption-oxidation flow-through cells for the indiscriminant degradation of explosives with diverse physicochemical properties within wastewater.
