OSTI ID:564822
Chemical oxidation processes that result in the generation of the hydroxyl radical (OH) have been referred to as advanced oxidation processes (AOPs) by the American Water Works Association. The U.S. Army Engineer Waterways Experiment Station under the direction of the U.S. Army Engineer District, Kansas City, and in conjunction with Woodward-Clyde Consultants, Overland Park, KS, evaluated the comparative performance of four AOPs for removing trichloroethylene, RDX, HMX, trinitrotoluene, and 1,3,5-trinitrobenzene from a representative sample of groundwater from the Nebraska Ordnance Plant using bench-scale reactors. During 1990, this site was placed on the National Priorities List. Candidate AOPs that were evaluated were irradiation of hydrogen peroxide with ultraviolet (UV) light emitted from low-pressure mercury vapor UV lamps (LPUV-HP), irradiation with UV light emitted from a low-pressure mercury vapor UV lamp with ozone sparging (LPUV-OZ), irradiation of hydrogen peroxide with Uv light emitted from a medium-pressure mercury vapor UV lamp (MPUV-HP), and peroxone (ozone sparging with hydrogen peroxide dosing). The groundwater influent sample used in this study was a three-way composite (equal parts) of groundwater collected from three site observation wells (Wells MW-11A, MW-40B, and MW-47B). The experiments were performed using a 1-l borosilicate reactor configured to sparge ozone into the test solution.
