ABSTRACT:
A method and apparatus of washing laundry without hot water and detergent using a closed-loop ozonated wash water system wherein wash water maintained in a storage tank is ozonated by an ozone generator prior to use in the washing machine. The ambient air used in the ozone generator to generate the ozone is undried and temperature controlled. The system includes a novel injector including a vacuum pump for entraining ozone into the water in the storage tank. The spent wash water is collected, filtered and reused, thereby eliminating waste water disposal problems, resulting in considerable water and energy savings.
