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.

An electrolytic gas generator, adapted to continuous, flowing operation, comprising a hollow container having a wall including a permeable cation-exchange membrane, dividing said container into two compartments, an anode positioned in one compartment and a cathode positioned in the other compartment
An electrolytic gas generator, adapted to continuous, flowing operation, comprising a hollow container having a wall including a permeable cation-exchange membrane, dividing said container into two compartments, an anode positioned in one compartment and a cathode positioned in the other compartment, a bipolar electrode positioned in said anode compartment aligned between said anode and said membrane and being of a size and shape permitting contact with electrolyte on substantially all sides thereof, an outlet from said anode compartment for removal of gas therefrom, an outlet from said cathode compartment for removal of gas therefrom, first and second remote reservoirs located at a sufficiently lower level than said container that both compartments of said container must be filled against gravity, means for circulating electrolyte to and from said anode compartment and said first reservoir, means for introduction of salt and of make-up water into said first reservoir, means for circulating electrolyte to and from said cathode compartment and said second reservoir, means for introduction of make-up water into said second reservoir, said circulating means being operable to fill said compartments with sufficient electrolyte to permit electrolysis on energization of said anode and cathode, said generator being operable upon filling with electrolyte and energizing to produce a mixture of oxidant gases in said anode compartment and to discharge the same through said anode compartment gas outlet, and said lower location of said first and second reservoirs relative to said container causing at least one of said compartments to be drained by gravity flow on inactivation of the means circulating electrolyte thereto.
