  • Electrolytic process for the production of chlorine dioxide
    Patent number: 6740223
    Abstract: Chlorine dioxide is produced at high conversion rates from aqueous sodium chlorite solution by electrochemical oxidation in an undivided electrochemical cell. The cell utilizes an anode of high surface area through which the aqueous sodium chlorite solution flows into an interelectrode gap between the anode and a cathode. Water or acidified water is fed into the interelectrode gap to function as catholyte and also to dilute the electrolyzed sodium chlorite solution to provide an aqueous solution of chlorine dioxide exiting from the electrochemical cell.
    Type: Grant
    Filed: June 19, 2002
    Date of Patent: May 25, 2004
    Assignee: Superior Plus Inc.
    Inventors: Marek Lipsztajn, Ronald K. Schaible, Yuri Alexeevich Omelchenko, George Joseph Ranger

  • Chlorine dioxide generation for water treatment
    Patent number: 5965004
    Abstract: Chlorine dioxide is generated by electrochemical oxidation of sodium chlorite in an anode compartment of a cation-exchange membrane-divided cell in the presence of significant quantities of sodium chlorate and is recovered in a suitable recipient medium by passing the chlorine dioxide through a hydrophobic microporous membrane. Water balance in a continuous operation is maintained by removing water from the anolyte by transporting the same partly across the hydrophobic microporous membrane in vapor form and partly across the cation-exchange membrane.
