Abstract
A method and apparatus for 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 a washing machine. The spent wash water is collected, filtered and reused thereby eliminating waste water disposal problems an resulting in considerable water and energy savings. The ozone generator includes a unique air flow configuration to maximize ozone generation resulting in a high efficiency washing system.
