  • Patent number: 9332736
    Abstract: A portable system for recycling used animal litter, such as chicken litter, in place which one can use to accommodate a succession of animals, such as flocks, in the same commercial chicken house, with the same bedding material. The system comprises a litter pulverizer mounted within a hood-like housing, a high output ozone generator, fluidly connected thereto, which, in use, discharges ozone into a flux of pulverized animal litter and pathogen-laden dust particulates, killing pathogens and neutralizing ammonia odors in the process, and an ultraviolet light source for further sterilizing pulverized litter and for destroying excess ozone discharged with it from the hood-like housing's base. Enhancing the system's pathogen-killing capacity are at least one hot air blower also fluidly connected to the hood-like housing and a moisture detector. The latter measures, in real time, the dryness of ozone-treated litter being discharged from the hood-like housing onto the chicken house floor.

  • Publication number: 20030129255
    Abstract: This is a method of treating a wide range of skin lesions in tropical and decorative fish in which the animals to be treated are exposed to dilute suspensions of colloidal silver. During the course of treatment, colloidal silver is added periodically to the aquarium in which the fish lives. so that the water therein has a silver concentration on the order of 1 ppb. A suitable treatment procedure entails adding 1 teaspoon of colloidal silver which contains about 6 ppm of silver to 10 gallons of aquarium water every other day. This treatment has been found effective in healing some fish, ever those with rather large wounds in a matter of days. If a longer treatment period is required, then the colloidal silver addition is continued at the same rate and then 50 percent of the water is changed once a week, until the lesion(s) have healed. It was also found that bacteria and virus skin problems could be prevented by having silver colloidal concentrations of 0.3-0.5 ppb in the aquarium water.

  • Patent number: 6557356
    Abstract: A device for killing pathogens that grow on the surface of the evaporator coil within a conventional air conditioner and in the drip pan of its evaporator. Utilizing ultraviolet radiation which is well-known to kill a wide range of pathogens, the device comprises at least one elongated ultraviolet light source. This source is positioned in such a way that its light strikes both the evaporator and the drip pan. Also this source is mounted transversely to the flow path of air passing through the evaporator.
