Description:
This paper presents information on two pilot-field appliations of advanced oxidation technologies for contaminated groundwater with organis. The two UV/oxidation technologies were developed by Ultrox International of Santa Ana, California and Peroxidatrion Systems, Inc. of Tucson, Arizona. The Ultrox technology was demonstrated in 1989 with the U.S. Environmental Protection Agency's Superfund Innovative Technology Evaluation (SITE) program at the Lorentz Barrel and Drum (LB&D) site in San Jose, California. Peroxidation Systems technology was applied at the Old O-Field site located within the Aberdeen Proving Ground, in Maryland. The Ultrox system was evaluatwed for its effectiveness in treating the volatile organic compounds (VOCs) present in groundwater at the LB&D site. Achivement of VOC removals were greater than 90 percent under best operating conditions at that time. Most VOCs were removed through Chemical oxidation, however, for a few VOCs, stripping also contributed toward removal. The Treated goundwater met the applicable discharged standards at 95 percent confidence level for discharged into aocal waterway. There were no harmful air emissions to the atmosphere from the Ultrox system, which is equipped with an off-gas treatment unit. The Peroxidatrion Systems technology, achieved contaminated removal efficiencies of about 96 percent, and the treated wateer met the federal maximum contaminant levels for drinking water. The information presented includes a description of the technologies, factors affecting the technologies, and results from the two pilot-scale studies of the UV/oxidation treatment system applications.
