Abstract
Over the past four years, Ultrox International has demonstrated the efficacy of ultraviolet light-enhanced oxidation at industrial, Department of Defense and Superfund sites. Waters containing halogenated solvents such as trichloroethylene, perchloroethylene and other halogenated compounds have been successfully treated with UV/ozone or UV/hydrogen peroxide or UV with ozone and peroxide. Other contaminants such as benzene, toluene, xylene, hydrazines, phenols, chlorophenols, dioxanes, PCBs and pesticides in wastewaters and groundwaters have also been reduced to acceptable discharge standards. Summations of the above projects will be presented, along with some of the technological basis of this process. Data showing comparisons of UV-enhanced oxidation testing with traditional ozonation also will be presented based upon research conducted under government grants.
Design and cost data from pilot plant testing and from operations at full-scale commercial installations will be presented. The applications will cover ultraviolet/oxidation systems treating waste water in the wood treating industry, rocket fuel waste water, and groundwater containing chlorinated solvents at automotive, aerospace and electronics manufacturers.
A discussion of test results and process economics from a demonstration of the ULTROX® process in the U.S. EPA Superfund Innovative Technology Evaluation (SITE) Program also will be presented.
