Using Halogen Or Halogen-containing Compound Patents (Class 422/37)
  • Patent number: 7264773
    Abstract: The invention provides a method for generating a homogeneous aqueous mist solution containing a solvent such as water and a biocide agent such as chlorine dioxide, which would otherwise be unstable. The unstable biocide agent or chlorine dioxide is quickly dissolved or mixed with a mist of solvent causing the biocide agent to co-exist or co-mist therewith. The mist microencapsulates the biocide gas so that it does not decompose in the fumigation volume or space. The resulting homogenous mist solution provides a mist for delivering the biocide agent in a chemically stable form. Methods for mixing the separately generated mist and biocide gas include combining the mists in a Y-tube and then mixing the combination in a baffled mixing chamber, combining the mists in an area above their points of generation and then further mixing, and providing a series of mist generation units connected by a conduit for a carrier medium to pass to and connect the units and cause the mists to combine.

  • Patent number: 7261821
    Abstract: This invention relates to an automated process for efficiently treating an aqueous system with chlorine dioxide. The process results in high efficiency yields of chlorine dioxide on a continuous basis by minimizing the waste of precursor chemicals. Additionally, the process creates less environmental stress because the formation of unwanted by-products is minimized. The level of chlorine dioxide in the aqueous system treated and other parameters of the process are monitored and adjusted automatically to maintain them within acceptable levels.

  • Patent number: 7229647
    Abstract: A method of making a composition having the property of being able to store chlorine dioxide includes mixing an aqueous chlorine dioxide solution with a superabsorbent, water-soluble polymer that is substantially unreactive with chlorine dioxide and permitting a mixture formed thereby to form one of a gel and a solid composition. A method of delivering chlorine dioxide includes providing a gel or solid composition as described and degelling the gel or dissolving the solid composition to dispense the chlorine dioxide therefrom. A method of disinfecting a target such as water, wastewater, or a surface comprises delivering chlorine dioxide as above and permitting the polymer to precipitate out of the mixture. Aqueous chlorine dioxide is then recovered and applied to the target.

  • Patent number: 7186376
    Abstract: A sodium chlorite (NaClO2) solution is admixed with flowing water to form a flowing water and sodium chlorite (NaClO2) solution. A flowing water and acid solution is admixed into the flowing water and sodium chlorite (NaClO2) solution. The combined solutions are directed into and through a mixing chamber to form a homogenous, acidified sodium chlorite solution. The homogenous, acidified sodium chlorite solution is removed from the mixing chamber and is either utilized as a liquid or is frozen to form ice that is utilized. The acidified sodium chlorite solution provides a slow release of chlorine dioxide gas (ClO2) for use in water treatment, in food plant sanitation, in ice for icing food items, and as an antimicrobial solution for direct application to food items.

The device comprises an alkali metal or alkaline earth metal chlorite, e.g., sodium chlorite, and a chemical reagent comprising an acid or a material capable of releasing an acid upon exposure to liquid water, e.g., sodium bisulfate. The chlorite and the reagent are either combined as a mixture or are disposed as separate components adhered to the surface of one or more substrates. Upon exposure to liquid water, the chlorite and the reagent produce boundary layers. The chlorite and the reagent are disposed upon, and adhered to, the surface(s) of the substrates in a manner such that upon exposure to liquid water, the chlorite boundary layer comes into contact with the reagent boundary layer to thereby produce an aqueous chlorine dioxide solution.

  • Patent number: 6863905
    Abstract: A mixed bed of iodine source/iodine capture resin provides high flow rates that are useful for treatment of water. The ratio of source/capture resin can be adjusted to meet the goals of the system. If insufficient iodine is being provided, the source resin amount can be increased relative to the capture resin. If excess iodine or iodide are found in the treated water, the capture resin amount can be increased relative to the source resin. The release of iodine from the source resin and its effectiveness can be significantly enhanced by using a mixed bed system in which one or both of the source and the capture ion exchange resins have had their exchange sites saturated with the anion of an organic acid such as citrate and/or isocitrate. This significantly increases the amount of iodine released into aqueous solution and enhances the disinfecting power of that iodine.

  • Patent number: 6848482
    Abstract: An object is to provide a liquid-removing apparatus capable of sufficiently removing liquid adhering to packaging material (11). The liquid-removing apparatus includes a packaging material (11) having a projection formed at a predetermined position; first and second squeeze rollers (23, 33) which form a squeeze portion (P1) for removing liquid adhering to the packaging material (11); and an elastic body. The second squeeze roller (33) has main roller portions (53, 54) and a retractable roller portion (55) which retracts when the projection reaches the squeeze portion (P1). The elastic body urges a tubular sleeve (64) provided on the retractable roller portion (55) toward the packaging material (11). When the projection reaches the squeeze portion (P1) during transportation of the packaging material (11), the sleeve (64) is pushed by the projection and thereby decentered, so that the retractable roller portion (55) is retracted.

  • Patent number: 6838050
    Abstract: Methods of providing anti-infective activity to a medical device including the steps of exposing the medical device to an anti-infective oxidant, and transferring the anti-infective oxidant into a wall of the medical device. One embodiment includes the step of exposing a medical device that is at least in part within a patient to the anti-infective oxidant. Another embodiment includes the steps of exposing a medical device to an aqueous solution which produces the anti-infective oxidant and transferring a sufficient amount of the anti-infective oxidant into the medical device wall to provide the medical device with anti-infective activity. Also provided is an oxidant releasing member that has anti-infective oxidant releasably contained therein and that is configured to be disposed adjacent to the medical device.

  • Publication number: 20040253140
    Abstract: The invention concerns a method for mechanically cleaning and sterilizing medical and surgical instruments and appliances, which consists in: (a) cleaning the instruments and appliances with an aqueous cleaning solution and (b) sterilizing the instruments and appliances with an aqueous sterilizing solution. The invention is characterized in that chlorine dioxide is released in situ, from chlorite and an acid activator, as disinfectant during the sterilizing step. The invention is based on the use of chlorine dioxide as efficient disinfectant, not requiring separate production of said substance in a chlorine dioxide generator. The inventive method can be implemented in a standard instrument washing machine.

  • Publication number: 20040232087
    Abstract: The present invention provides a new method for the in situ generation of chlorine dioxide from a solution of sodium chlorite and carbon dioxide. The present invention produces effective levels of chlorine dioxide without having to resort to the use of hydrochloric acid, sulfuric acid, hydrogen peroxide, chlorine, sulfur dioxide, or methanol. By eliminating the use of toxic and/or hazardous compounds, the present invention provides a safer means for generating and using chlorine dioxide in a wider variety of applications than previously possible. For instance, the present invention can easily be adapted for the treatment of combustion exhaust gases, flue gases, cooling towers, chilled water systems, contaminated groundwater, and agricultural produce or products.
