Ozone is used in laundry waste water treatment. Ozone treated laundry waste water can be recycled for non portable applications like flushing, gardening, washing & cooling tower make up water etc. Ozone treated laundry waste water is further treated by U.F. & RO for waste water to be reduced in laundry applications. Ozone very efficiently reacts with most of the surfactants presents in laundry waste water & reduces COD, BOD, for the waste water.
