ABSTRACT:
A redox bipolar cell fabric washing system and method is disclosed that provides for washing fabrics without the use of any added detergents, fabric softeners, or bleaches, or other chemical al additives. The system includes a conventional fabric washing machine with a redox bipolar cell that through a circulation pump continuously treats the wash water by using mixed oxidants or charged wash water to remove contaminants from the fabric. The redox cell includes a housing, a plurality of cathode plates, a plurality of membranes, and a plurality of anodes proximately positioned in an alternate manner with a plurality of flow channels in the housing. The cell produces charged wash water by an electrochemical reaction utilizing electrically charged anodes and cathodes with semi permeable membranes, wherein the oxidation reduction potential of the charged wash water is continuously controlled with a sensor to determine when the fabrics are clean.
