  • Patent number: 6984304
    Abstract: The present invention provides an ozone generation and delivery system that lends itself to small scale applications and requires very low maintenance. The system includes an anode reservoir and a cathode phase separator each having a hydrophobic membrane to allow phase separation of produced gases from water. The system may be configured to operate passively with no moving parts or in a self-pressurizing manner with the inclusion of a pressure controlling device or valve in the gas outlet of the anode reservoir. The hydrogen gas, ozone gas and water containing ozone may be delivered under pressure.

  • Patent number: 6866806
    Abstract: A method for securing an anode, a cathode and an ion exchange membrane disposed between the anode and the cathode within a premolded thermoplastic frame. The frame both secures the anode the cathode and the ion exchange membrane within the frame and further maintain the anode, cathode and membrane in intimate contact. Additionally, injection molding around the premolded thermoplastic frame may be performed or alternatively, injection molding around a plurality of thermoplastic frames.

  • Patent number: 6860976
    Abstract: Electrochemical apparatus and methods that support periodic, non-steady state, or discontinuous operation without suffering degradation of materials or loss of efficiency. The invention provides a means for positioning one or more electrodes into contact with electrolyte and means for retracting the one or more electrodes out of contact with the electrolyte. The means for positioning and means for retracting may be the same device or different devices. The means for positioning and means for retracting may be designed to provide automatic, passive, or fail-safe retraction of the electrode upon a given shutdown condition, such as a voltage of less than one Volt being applied between the first and second electrodes, expiration of a time period, an ozone concentration greater than a setpoint ozone concentration, contact pressure of less than 5 psig, and combinations thereof.

  • Patent number: 6712951
    Abstract: An ozone generator which operates at constant pressures to produce a continuous flow of ozone in an oxygen stream having from 10% to 18% by weight of ozone. The ozone generator includes one or more electrolytic cells comprising an anode/anode flow field, a cathode/cathode flow field, and a proton exchange medium for maintaining the separation of ozone and oxygen from hydrogen. The ozone generator also has an anode reservoir which vents oxygen and ozone and a cathode reservoir which vents hydrogen. The anode reservoir can be filled from the cathode reservoir while continuing to produce ozone. The ozone generator is readily configured for self-control using a system controller programmed to operate the anode reservoir at a constant pressure.

  • Patent number: 6458257
    Abstract: The present invention provides for the electrochemical generation of ozone for use in “point-of-use” applications. The electrochemical ozone generators or systems of the present invention may be used to provide disinfected water, ozone-containing water, and/or ozone gas. Disinfected water may be produced by introducing ozone gas into a potable or purified water source for the purpose of disinfecting or controlling the microorganisms in the water source. Ozonated water or ozone gas may be produced and provided for various anti-microbial and cleansing applications of the consumer, such as washing food, clothing, dishes, countertops, toys, sinks, bathroom surfaces, and the like. Furthermore, the ozone generator may be used to deliver a stream of ozone-containing water for the purpose of commercial or residential point-of-use washing, disinfecting, and sterilizing medical instruments and medical equipment.
