Mitsubishi Electric Supplies Ozone Water Treatment System for Water Purification in Kobe Metro Area

Tokyo, August 17, 2010 - Mitsubishi Electric Corporation (TOKYO: 6503) announced that it has supplied an ozone water treatment system comprising an ozone generator, a contact tank and an off-ozone gas destructor to the Hanshin Water Supply Authority's Amagasaki Waterworks, which supplies purified water to the cities of Kobe, Amagasaki, Nishinomiya and Ashiya. The newly installed equipment will start operating in August 2010.

Ozone systems disinfect, deodorize, decolorize and remove organic matter with far greater oxidizing power than chlorine, while producing harmless oxygen as the only by-product. Ozonization is a highly efficient water treatment technology with low environmental impact.

Amagasaki Waterworks, located in Amagasaki City, Hyogo Prefecture, Japan, has supplied purified water to the four cities since 1942. In 2001, its first high-level water treatment equipment unit was installed to supply clean and palatable water through ozone treatment and activated carbon filtration. The new system will increase water treatment capacity and help stabilize water supply.
