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.

Abstract: A process for an electrochemical reduction of a reducible dye by contacting said reducible dye with a cathode comprising a support of an electrically conductive material and an electrically conductive, cathodically polarized layer formed thereon in situ by alluviation comprises conducting said electrochemical reduction in the presence of a base.

Abstract: An improved laundry treatment system comprises a washer which is connected to discharge used water to a tank for filtration and recirculation to the washer, and a tank containing water for making up losses in the wash cycle, and an electrolytic cell therein comprising an enclosed compartment. The electrolytic cell comprises an enclosed compartment containing an anode and a cathode supported on the outside and inside respectively of an opening in the wall of the compartment open to the surrounding liquid when the compartment is immersed in the water in said tank for producing mixed oxidants dissolved in the make up water for oxidizing deleterious components without damaging the fabric being washed.
