Abstract (en)
[origin: WO2013112197A1] Method and system for controlling a concentration of ozone is a washing machine to be at or below a target value so that a cumulative contact time of the ozone with laundry approaches a duration of time of an entire wash stage or cycle thereby ensuring killing of any infectious diseases. The method comprises supplying ozone to the washing machine, upon filling the washing machine, and supplementing the supplied ozonated water by supplying additional ozone to the wash machine during each wash stage or cycle, and controlling the supply of ozone supplied to the wash machine so that the concentration of ozone sampled or exhausting from the washing machine is controlled to be within a control band between 60% and 100% of the target value and the cumulative contact time of the ozone with the laundry is at least 60% of the duration of the entire wash stage or cycle.
