Ultrox International Ultraviolet Radiation/Oxidation Technology: ApplicationsAnalysis Report

摘要

In support of the U.S. Environmental Protection Agency's (EPA) SuperfundInnovative Technology Evaluation (SITE) Program, the report evaluates both treatment efficiency and economic cost from the SITE demonstration and seven case studies. The Ultrox technology simultaneously uses ultraviolet (UV) radiation, ozone, and hydrogen peroxide to oxidize dissolved organic contaminants found in groundwater or wastewater. Under the SITE Program, the Ultrox technology demonstration was conducted at the Lorentz Barrel and Drum (LB&D) site, San Jose, California, in February and March of 1989. During the demonstration, the Ultrox system achieved volatile organic compound (VOC) removals greater than 90 percent. The majority of VOCs were removed through chemical oxidation. However, stripping also contributed toward removal of a few VOCs, such as 1,1,1-trichloroethane (1,1,1-TCA) and 1,1-dichloroethane (1,1-DCA). The treated groundwater met the applicable National Pollutant Discharge Elimination System (NPDES) standards for discharge into a local waterway. In addition, there were no harmful air emissions to the atmosphere from the Ultrox system, which is equipped with an off-gas treatment unit.
