  • Patent number: 8202548
    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.

The TCM may be applied by spraying the habitat with a solution of TCM, by dusting the habitat with powdered TCM or by treating bedding/litter with TCM. This process produces healthier animals and as such the productivity of a given grow out is increased. The process of this invention is particularly suited to animal habitats which are used to raise batches of hogs, cattle, turkeys and chickens on a continuing basis. The process of this invention further reduces the bacteria count of the animal habitat.

The surface element is permeable, such that the resultant pressure of a user stepping on the sanitizing mat squeezes the sanitizing solution out of the sponge element and through the surface element to sanitize the feet or footwear of the user. The surface element comprises an abrasive material, such that debris from the user's feet or footwear may be loosened and left on the surface element. The user then steps off of the mat without carrying germs or bacteria on the soles of their feet or footwear.

  • Patent number: 7824557
    Abstract: A process has been found which increases the efficiency and effectiveness of introducing antimicrobial compounds into complex biofilm matrices through the use of liposome carriers, thereby removing the biofouling in industrial water bearing systems, including piping, heat exchanges, condensers, filtration systems and fluid storage tanks. According to one embodiment of the invention, antimicrobial compound containing liposomes are added to water systems prone to biofouling and biofilm formation. The liposomes, being similar in composition to microbial membranes or cells, are readily incorporated into the existing biofilm. Once the antimicrobial compound containing liposomes become entrained with the biofilm matrix, the decomposition or programmed disintegration of the liposome proceeds. Thereafter the biocidal aqueous core is released to react directly with the biofilm encased microorganisms.

  • Publication number: 20100272603
    Abstract: This invention concerns a hydrogen peroxide sterilization device, with injection of hydrogen peroxide vapour, provided with a vaporizer that feeds a sterilization chamber, with a dose that varies in function of the control performed by a computer or control unit. The vaporizer works with a pressure inferior to the atmospheric one and is heated by an electrical resistance heater, or by micro-waves. All the vaporization process is made in vacuum, by heat or ultra-sounds. The filling of the sterilant agent is made drop-by-drop by a capillary tube which transforms the liquid into a pulverized gas. The computer controls the electrical valve following the dosing pump from the pressure and/or temperature information that comes from various pressure and/or temperature sensors, whereby the pressure inside the chamber is maintained during the sterilization process in a constant predefined value, appropriate to use simple cellulose-base paper or paper composed to the packaging of the devices.

  • Patent number: 7767095
    Abstract: A method and apparatus for implementing pathogen reduction within a poultry processing or food processing plant that uses water that has been treated with chloramines at an advantageous dosage before being introduced to the production process at processing steps. The water treated with chloramines may be from a fresh water source or reclaimed water from the processing plant. The reintroduction of the treated reclaimed water advantageously causes a dramatic reduction in the levels of microorganisms associated with poultry processing, while substantially conserving water use.
