Abstract

A method and system of controlling a concentration of ozone sampled or exhausting from 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 cycle of the washing machine thereby ensuring killing of any infectious diseases. The method comprising the steps of supplying only ozonated water to the washing machine upon filling the washing machine, supplementing the supplied ozonated water by supplying additional ozone to the wash machine during each wash 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 time of the entire wash cycle.
