Abstract: A process and system for reducing the concentration of odorous contaminants, primarily hydrogen sulfide, in the vapor spaces of sewage handling and treatment systems, primarily the vapor spaces of sewage trunk lines, by injecting a fine spray, mist or fog of a dilute solution of hydrogen peroxide and a base selected from a group consisting of sodium hydroxide, potassium hydroxide, ammonium hydroxide and sodium carbonate to mix intimately with the vapor flow. The peroxide and base solutions may be pre-mixed and diluted with water and injected through atomizing nozzles utilizing compressed air as an atomizing fluid. The system may also provide for separate storage of the peroxide and base solutions, mixing of the peroxide and base solutions with dilution water with in-line mixing devices and direct injection with or without compressed air atomization into the vapor space.

Abstract: A method for sterilizing products to inactivate biological contaminants such as viruses, bacteria, yeasts, molds, mycoplasmas and parasites is disclosed. The method involves irradiating the product at a low dose rate from about 0.1 kGy/hr. to about 3.0 kGy/hr. for a period of time sufficient to sterilize the product. The method does not destroy sensitive materials such as blood and blood components. Further, the method does not require pre-treatment of the product such as freezing, filtration or the addition of chemical sensitizers.

Abstract: A method and corrosion inhibitor for inhibiting corrosion of metal equipment in an aqueous medium comprising components selected from the group consisting of Skeletonema costatum, fish, other algae, and a combination thereof. The method comprises incorporating into the medium a corrosion inhibiting amount of a water soluble corrosion inhibitor comprising an N-ethoxy, 2-substituted imidazoline. The N-ethoxy substituent comprises a quantity of ethylene oxide effective to render the imidazoline water soluble. The corrosion inhibitor is rendered more environmentally compatible by shortening the number of carbon atoms in the fatty acid chain at the 2-position of the imidazoline. The fatty acid chain consists essentially about 18 carbon atoms or less, preferably about 10 carbon atoms or less, most preferably from about 6 to about 8 carbon atoms.

Abstract: The present invention relates to a system for disbursing ozone throughout a poultry house in order to disinfect the same and to reduce the concentration of pathogens found within the poultry house. An ozone generator is associated with the poultry house and ozone produced by the generator is directed through a lower main duct that disburses ozone upwardly through litter disposed on the poultry house floor. In addition, the same generator directs the produced ozone through an upper main duct and ozone is disbursed from conduits leading from the upper main duct into the air.

Abstract: A method for sterilizing a device, includes the following steps: contacting the device with liquid sterilant outside or inside a sterilization chamber at a first pressure, placing the device in the chamber before or after the contacting step, and decreasing the pressure of the chamber to a second pressure below the vapor pressure of the liquid sterilant. At least the decrease in pressure below about the vapor pressure of the liquid sterilant occurs at a pumpdown rate of less than 0.8 liters per second, calculated based on the time required to evacuate the chamber from atmospheric pressure to 20 torr when the chamber is empty and dry.
