A system for treating laundry with ozone including the capability to re-use at least a portion of the water utilized during the wash process, said system comprisinga laundry machine defining a cavity therein for receiving a wash liquor comprising water from a municipal water source, said laundry machine comprising a drain for draining the wash liquor from the cavity and a means for selecting a wash load from a predetermined plurality of wash load selections;

  • a controller in electrical communication with said selecting means, said controller receiving a load signal from said selecting means and transmitting a control signal corresponding to the wash load;

    an ozone generator in electrical communication with said controller, said ozone generator receiving the control signal from said controller and generating a variable amount of ozone in response to the control signal;

    an air dryer in electrical communication with said controller and in fluid communication with said ozone generator, said air dryer providing desiccated air to said ozone generator;

    a sparging pump in electrical communication with said controller and in fluid communication with said ozone generator, said sparging pump pumping the ozone generated by said ozone generator from said ozone generator to said laundry machine;

    an injector assembly in fluid communication with said sparging pump and said laundry machine, said injector assembly positioned adjacent said drain of said laundry machine for dispersing the variable amount of ozone generated by the ozone generator in response to the control signal directly into the wash liquor in the cavity defined by said laundry machine;

    a sump in fluid communication with said laundry machine;

    a sewer in fluid communication with said laundry machine;

    a T-valve in fluid communication with and positioned between said sump and said laundry machine and in fluid communication with and positioned between said sewer and said laundry machine, said T-valve selectively diverting wastewater from the cavity defined by said laundry machine to said sump and to said sewer;

    a sump pump in fluid communication with and positioned between said sump and said laundry machine, said sump pump pumping the wastewater diverted to said sump to the cavity defined by said laundry machine; and
