ABSTRACT:
A water treatment method and apparatus is described for generating a supply of activated water containing oxidants, including hydroxyl radicals, hydrogen peroxide, and hydroperoxy radicals, but excluding ozone. The apparatus includes a generator having ultraviolet lamps to which air is exposed to create activated air. To suppress the generation of ozone in the activated air, the air subjected to the ultraviolet lamps is maintained at a relative high humidity. Also, the activated air is generated in the presence of a catalyst and using 254 nm light, both of which are believed to aid in the destruction of any ozone generated by the exposure of the air to other wavelengths of the uv light. The catalyst also provides additional oxidants in the air. The activated air is entrained in the water using an injector to thereby produce the activated water. A mixer can be used to subject the activated water coming from the injector to turbulent flow conditions to thereby further break up the activated air within the water. In one specific application, the activated water is utilized as a part of a method and apparatus for washing laundry. The laundry is agitated in wash water made up from the activated water. The wash water can be continuously recirculated from the chamber containing the wash water and laundry, through the injector where additional activated air is added, then through the mixer, and thereafter back into the chamber.
