#94-1 Trichloroethylene Removal Technology at Hiroshima University
Hiroshima University has developed a new method for highly efficient removal of trichloroethylene from groundwater. Unlike conventional methods, this technique uses acetic acid to elute trichloroethylene from activated carbon, which is then decomposed by ozone bubbles several tens of micrometers in diameter. This is expected to reduce treatment costs and prevent dioxin formation. This technology has been adopted by the Ministry of Economy, Trade and Industry (METI) as part of the Consortium for Immediate Regional Revitalization R&D Project, and a pilot plant is scheduled to be completed by the end of June 2002, with a demonstration plant to be built by the spring of 2003.
