Abstract
A continuous electrolytic generator is disclosed having two sealed compartments, separated by a cation exchange membrane, having a cathode in one compartment, and an anode in the other. A bipolar electrode is positioned in the anode compartment between the cation exchange membrane and the anode. The bipolar electrode may be supported on the dividing wall spaced from the ion-exchange membrane. The bipolar membrane may also be supported on the anode on insulators in spaced relation thereto. The generator has exterior reservoirs for continuously circulating solutions to and from the anode and cathode compartments. A third reservoir receives make-up water and salt and is connected to supply brine to the exterior anode reservoir. The cell produces a mixture of oxidant gases containing chlorine, chlorine dioxide, oxygen, hydrogen peroxide, and possibly ozone, from the anode compartment which is connected to a gas collection and utilization system, e.g., a venturi in a flowing water line. The system includes a pressure switch, responsive to vacuum in the venturi, operable to energize the pumps circulating solutions from the exterior reservoirs only when water is flowing.
