Ozone cleaning operation

Abstract

An apparatus and method for using a dry cleaning machine to clean laundry that reduces environmental impacts by the substitution of ozone for the hazardous solvents traditionally used in the dry cleaning washing process. The apparatus and method for dry cleaning includes the steps of filtering the water whereby any debris present in the water is removed, measuring the dissolved ozone concentration of the water, recirculating the water between the tank and the water purifier until a desired ozone concentration is realized ensuring that the desired dissolved ozone concentration of the water is attained prior to the start of the cleaning process and continuously recirculating the water through the dry cleaning washing machine, the water purifier, and the tank during the cleaning process.
