Improvements on the electrolytic reactor and process of U.S. Pat. No. 5,419,816 and copending U.S. application Ser. No. 08/400,950, filed Mar. 9, 1995, now U.S. Pat. No. 5,609,742, are disclosed for the controlled oxidation and reduction of inorganic and organic species in dilute aqueous solutions. More specifically, other physical forms and additives for the modified ion exchange material can be used in the packed bed electrolytic reactor, including powdered ion exchange materials and solid membranes containing the modified ion exchange materials. Direct contact with only one electrode, the anode for oxidation, and the cathode for reduction, is required for the modified ion exchange resin, instead of with both electrodes. Superior performance is also demonstrated for bipolar operation of the electrolytic reactor in comparison to monopolar operation. Preferably, the polarity of the electrodes is reversed every 1 to 60 minutes. Finally, other point of use applications are disclosed for the electrolytic reactor and process, including sanitization and sterilization, such as useful in the medical, dental and veterinary industries, food and animal disinfection, bacteria control and waste treatment.

대표청구항 ▼

[ What is claimed is:] [1.] An electrolytic process for oxidizing a species in a dilute aqueous solution, comprising the steps of:passing an aqueous feed solution containing said species to be oxidized through a packed bed of modified cation exchange material interposed between an anode and a cathode, with said bed of modified cation exchange material in direct contact with at least said anode;applying a direct current across the anode and cathode in a bipolar fashion;contacting said feed solution with said bed for a time to cause at least a portion of said species to be oxidized by said modified cation exchange material so that said aqueous solution contains said species in an oxidized form; andrecovering the aqueous solution containing said oxidized species.
