    Abstract: A water conditioner that utilizes ionic flow and selective ionic filtering to control water hardness and/or pH. In some embodiments, the water conditioner includes one or more conditioning cells each having electrodes and a cathode side and an anode side separated by an ion-selective filter. The ion-selective filter is design/configured/selected to pass alkaline earth metal cations and block corresponding carbonate anions. When the electrodes are energized and water is present on the cathode and anode sides of the filter membrane, the alkaline earth metal cations pass from the anode side to the cathode side through the membrane, while the membrane blocks carbonate ions on the cathode side from passing to the anode side. In this manner, alkaline earth metal cations, and water hardness, can be reduced in the anode flow.

    Abstract: A system for hydrogen sulfide removal from a sour gas mixture including hydrogen sulfide. The sour gas mixture is reacted with a transition metal compound in a scrubber. Sulfide from the hydrogen sulfide is oxidized to form elemental sulfur and the transition metal is reduced to form a reduced state transition metal compound. An electrochemical redox reaction is performed including the reduced state transition metal compound to regenerate the transition metal compound in an electrolyzer including a power source. During the electrochemical redox reaction a voltage from the power source applied to the electrolyzer is controlled to regenerate the transition metal compound at a rate sufficient to match a flow rate of hydrogen sulfide into the scrubber or maintain a predetermined maximum hydrogen sulfide level out from the scrubber. The transition metal compound regenerated is returned to the scrubber for the reacting.

  • Publication number: 20120234693
    Abstract: An electrolyzed water production apparatus and method safely and simply produce electrolyzed water having a sterilizing action, having a physiologically neutral pH value, and, in addition, simultaneously with strong acidic electrolyzed water and strong alkaline electrolyzed water depending upon the structure. The electrolyzed water production apparatus has an electrolyzer tank with an end that receives or stores raw water, and a power supply. The interior portion of the electrolyzer tank is partitioned by a plurality of diaphragms into a plurality of regions. An anode and a cathode (constituting an electrode pair) are positioned on either side of the diaphragm. In a certain region of the electrolyzer tank, an anode and a cathode are arranged so as to face each other without a diaphragm sandwiched between them. When raw water for electrolysis is electrolyzed, electrolyzed water having a desired pH of a neutral range is produced during electrolysis.

  • Patent number: 8242026
    Abstract: Provided is a method for performing etching process or film forming process to a substrate W whereupon a prescribed pattern is formed with an opening. The method is provided with a step of mixing a liquid and a gas, at least one of which contains a component that contributes to the etching process or the film forming process, and generating charged nano-bubbles 85 having a diameter smaller than that of the opening formed on the semiconductor substrate W; a step of forming an electric field to attract the nano-bubbles onto the surface of the substrate W; and a step of performing the process by supplying the substrate with the liquid containing the nano-bubbles 85 while forming the electric field.

  • Patent number: 8216445
    Abstract: A nanoporous insulating oxide deionization device, method of manufacture and method of use thereof for deionizing a water supply (such as a hard water supply), for desalinating a salt water supply, and for treating a bacteria-containing water supply. The device contains two composite electrodes each constructed from a conductive backing electrode and a composite oxide layer being an insulating oxide or a non-insulating oxide and an intermediate porous layer. The composite layer being substantially free of mixed oxidation states and nanoporous and having a median pore diameter of 0.5-500 nanometers and average surface area of 300-600 m2/g. The composite layer made from a stable sol-gel suspension containing particles of the insulating oxide, the median primary particle diameter being 1-50 nanometers.

  • Patent number: 8211288
    Abstract: Feed water comprising an aqueous salt solution is supplied to an anode chamber and to a cathode chamber. The feed water is cathodically electrolyzed in the cathode chamber to produce alkaline electrolyzed water (catholyte) and is anodically electrolyzed in the anode chamber to produce electrolyzed water (anolyte) whose pH is modified. A portion of alkaline catholyte from the cathode chamber is recycled back to the feed water during continuous electrolysis to provide a blend of feed water and alkaline catholyte to the anode chamber to control pH of the anodically electrolyzed water therein to provide more stable bactericidal activity thereof over time.

  • Patent number: 8147701
    Abstract: The present invention relates to a treatment process applicable to degrade or transform organic and inorganic pollutants, commonly found in industrial wastewaters, contaminated aquifers and gas emissions, in which reduction or oxidation reactions (e.g. redox reactions) are involved. The treatment concept comprises reactors in which catalysts, with redox mediating properties, have been immobilized on ion exchange resins in order to improve and accelerate the transformation of priority pollutants by chemical or biological means.

  • Publication number: 20120067738
    Abstract: A method and apparatus are provided for generating and applying a sanitizing liquid. The method includes moving a mobile floor cleaning device along a floor and electrochemically activating a liquid on the mobile floor cleaning device by passing the liquid through a functional generator having first and second electrode chambers that are separated by an ion exchange membrane such that the liquid activated in the first electrode chamber comprises O3 molecules. Substantially all of the liquid activated in the first and second electrode chambers are dispensed from the device within 5 seconds of the time at which the liquids are activated by the functional generator without an intermediate step of storing either of the liquids produced in the first or second electrode chambers. At least some of the dispensed liquid is recovered from the floor with a recovery device carried by the mobile floor cleaning device.
