  • Patent number: 7727465
    Abstract: A system and method for extracting active elemental iodine from the contact of water with stored crystal iodine and for introducing the extracted elemental iodine into a water supply line and/or otherwise making the extracted elemental iodine available for an intended use. The system operates by allowing a portion of the water entering from a water supply line to be redirected to a first housing where it makes contact with stored crystal iodine causing to extract active elemental iodine. The iodinized water leaves the first housing and enters a second housing where it makes contact additional stored crystal iodine to help stabilize the elemental iodine concentration. The system can be designed to provide the elemental iodine in more than one potency concentration through the use of a metering valve and different travel routes for the elemental iodine out of the second housing.

  • Patent number: 7718121
    Abstract: A method and a reaction apparatus which can safely and continuously treat/discharge especially a short object is treated without any direct contact with a gas atmosphere, and which surely/efficiently treats the object with a gas without any uneven treatment. A short object A to be treated is put in a hermetically sealed cylindrical treatment section 1. In the treatment section 1, the object is held in a predetermined position by a first operation piece 11 to be treated with a gas for a predetermined time. Then, the holding by the first operation piece is released to move the object A by a desired distance. Subsequently, the object is held in a predetermined position by a second operation piece 12 to be treated again with the gas for a predetermined time, and then a treated object A1 is discharged. This discharged treated object A1 is conveyed to the outside of the apparatus.

  • Patent number: 7682560
    Abstract: As shown in FIG. 1 there is one embodiment of a fumigation apparatus in the form of a module (8) including a panel (10) which can be positioned in or at an opening of an enclosed space in use to define a fumigation chamber. Fumigant inlet means in the form of an orifice (12) are arranged in the panel (10) to allow a flow of a fumigant directly into the fumigation chamber. A nominal number of mixing fans, in this case two fans (16) and (18), thoroughly circulate gases within the fumigation chamber when operating. The module (8) includes a system control box (14) linked to the fumigant delivery orifice (12) and valve system which functions to control the flow of toxic gas into the fumigation chamber. The panel (10), when positioned in use, is secure against the passage of fumigant and gases by means of an inflatable rubber seal (22) which is located around a lip edge perimeter of the panel (10).

    Abstract: Disclosed is a method of preparing a biocide having improved durability of its biocidal activity as well as disinfection efficiency at an initial stage, comprising the steps of: (a) preparing stabilized alkali or alkaline earth metal hypochlorite having a pH at least 11 by mixing a chlorine oxidant including alkali or alkaline earth metal hypochlorite with a stabilizer in an alkali solution; (b) preparing a bromide ion source; and (c) adding the bromide ion source prepared in step (b) into the stabilized alkali or alkaline earth metal hypochlorite prepared in step (a). Also, a method of controlling the growth of microorganisms using a biocide prepared by the method of the present invention is disclosed.

  • Patent number: 7329385
    Abstract: A device for air stream, fluid and vessel decontamination generally comprises an air-inlet portion, through which air enters the device; an iodine-treatment portion; and a bubble-forming element through which iodine-laden air bubbles are released from the device into the fluid contained within the vessel. Such a device and related method substantially reduces, eliminates, or maintains microbial contamination of: air entering the device for release into the vessel; the fluid within the vessel; the interior surfaces of the vessel; and surfaces of any additional components coming into contact with the fluid or the air released from the device.

  • Patent number: 7326382
    Abstract: A method of sterilizing a site or contained volume includes providing an aqueous biocide solution containing a biocide agent such as hydrogen peroxide. A mist of reactive biocide droplets is generated by atomization at ambient pressure from the biocide solution and a flow of carrier medium or air is provided in communication with the mist. The flow of carrier medium is controlled to generate a biocide mist comprising a concentration of stable mist droplets within the carrier medium. By controlling aersolization, extraction and delivery of the stable mist droplets, a sufficient portion of the stable mist droplets for a sterilizing treatment of a designated site do not coalesce prior to treatment interaction with the treatment site. The process of formation, stabilization and extraction are done in-situ so that droplets do not coalesce during transport.

  • Publication number: 20080025870
    Abstract: One aspect of the present invention relates to separating a gas, such as chlorine dioxide, from a solution. In another aspect of the invention, the separated gas is then used for the sterilization or sanitation of items, such as food, food storage containers, other food contact surfaces, medical devices, and the like. In yet another aspect of the invention, that gas is then decomposed or otherwise neutralized after contacting the item. In yet another aspect of the invention, the separated gas is dissolved or otherwise introduced into a pure solution, such as water, to form highly pure solution containing the gas.

  • Patent number: 7323138
    Abstract: A method for treating an article which involves exposing an article within a space to a concentration of chlorine dioxide gas that exceeds the IDLH, STEL or TLV, then reducing the concentration of chlorine dioxide gas within the space to a positive quantity below the IDLH, STEL or TVL. Thereafter, additional chlorine dioxide gas is introduced into the space, but the concentration within the space remains below the IDLH, STEL or TVL.
