Abstract: A system and method for treating laundry with ozone is provided including a controller that receives a load signal based on a wash load selection. In response to the load signal, the controller transmits a power supply control signal to a variable power supply to vary an output potential to an ozone generator. The controller transmits a dryer control signal to an air dryer to provide desiccated air to the ozone generator. The controller transmits a sparging pump control signal to a sparging pump to pump the ozone generated by the ozone generator to a sparging rod adjacent the sump of the laundry machine where the ozone is dispersed directly into the wash liquor. In a preferred embodiment, an adapter removably secures the sparging rod to the wall of the laundry machine so that the sparging rod may be readily removed for cleaning, repair or replacement.

Abstract: A system for treating laundry with ozone including a controller that receives a load signal based on a wash load selection. The controller varies an output potential from a variable power supply to an ozone generator in response to the load signal. The ozone generator produces different levels of ozone corresponding to the output potential. A wash liquor is drawn out of a laundry machine and sent through a filter past an injector adjacent a venturi. The injector entrains ozone from the ozone generator into the wash liquor and the wash liquor is returned to the laundry machine.
