  • Patent number: 8684799
    Abstract: An apparatus and method for cleaning carcasses is described and illustrated, as is a device for mixing a cleaning substance that can be used in such applications. In some embodiments, the apparatus and method utilize a multi-phase cleaning substance spraying procedure in which the cleaning substance has desired levels of chlorine dioxide and is delivered to the carcasses at desired flow rates, both of which can vary between phases of the procedure and/or at different locations of the carcasses being cleaned.

  • Publication number: 20100272825
    Abstract: Animal carcasses are disinfected by applying to the surface of the animal carcass an acidified solution of chlorine dioxide. The chlorine dioxide solution should have a pH of about 2-3 and a concentration of 1-100 ppm. The contact time for the solution onto the carcass surface should be from about 5 seconds to about 60 seconds.

  • Publication number: 20100098782
    Abstract: Animal carcasses are disinfected by applying to the animal carcass an aqueous solution of sodium acid sulfate that does not include a chlorine-containing composition. The solution is maintained at from about pH 1.0 to about pH 2.5 and can optionally include a second acid such as citric acid, lactic acid, or combinations thereof.

  • Publication number: 20080025874
    Abstract: A device and method for measuring the concentration of a water soluble gas within an aqueous solution. In some embodiments, the solution has suspended solids, color, and turbidity. The device includes a gas release device in communication with a gas monitoring device. The gas release device is configured to cause the gas within the aqueous solution to transfer from the solution to an ambient gas phase. A chamber captures the released ambient gas and directs the gas toward the gas monitoring device.

  • Patent number: 5800732
    Abstract: An all-in-one cooling water treatment composition includes a high concentration of peroxide, preferably hydrogen peroxide, in combination with a polyhydric alcohol and a phosphonate to stabilize the peroxide in a concentrated solution. The composition further includes a yellow metal corrosion inhibitor such as aromatic triazole and optionally polymeric dispersants and ferrous metal corrosion inhibitors and/or molybdate metal corrosion inhibitors. In this composition the phosphonate, preferably HEDP, acts both to stabilize the peroxide and, at the same time, provides anti-scalant treatment for the cooling tower. Due to the stability provided by the HEDP and its anti-scalant properties, this can be formulated as an all-in-one treatment composition which is stable at high concentrations and can be added to effectively control biocidal activity, scale and corrosion.
