Abstract:
A method of treating laundry with ozone comprising the steps of:analyzing the characteristics of the laundry to be washed; obtaining a properly sized apparatus for the treatment of laundry comprising: a plurality of tanks, each of said tanks having an interior space and each of said tanks having a water inlet and a water outlet, wherein a first tank is a transfer tank and a second tank is a supply tank; a water source connected in fluid flow communication with said tanks; a water purification means disposed between said water source and said supply tank in fluid flow communication with said tanks wherein ozone may be introduced into the water flow to provide wash water having a dissolved ozone concentration wherein said water purification means further comprises a control means; the supply tank further comprising a monitor to determine the dissolved ozone concentration of the wash water, at least one washing means in fluid flow communication with said supply tank and said water purification means wherein said washing means further comprises a plurality of wash water supply ports wherein a first wash water supply port is cold and a second wash water supply port is hot; whereby wash water having a desired dissolved ozone concentration may be delivered to said washing means; setting the concentration level of dissolved ozone to be delivered to said washing means; introducing ozone into said wash water; maintaining a supply of wash water in said supply tank; re-circulating the wash water from the supply tank through said water purification means if the concentration of dissolved ozone is below the desired dissolved ozone concentration until the desired dissolved ozone concentration is attained; and delivering ozonated water having a preset dissolved ozone concentration to said washing means upon demand.
