  • Patent number: 8277735
    Abstract: This document describes a high intensity air purifier (HAIP), a super oxidation purifier, and a controller for controlling operation of any of various purification systems. In some implementations, a HAIP includes an air purifier system coupled within a housing having an air inlet and an air outlet. The air purifier system includes a pre-filter coupled to the air inlet, an axial fan for receiving and forwarding air from the air inlet. The air purifier system further includes a UV reaction chamber having a UV-light source for providing UV light to the forwarded air from the air inlet and a reflective lining to reflect the provided UV light, to provide UV purified air from the UV reaction chamber. The air purifier system further includes a chemical catalyst cartridge for receiving the UV purified air from the UV reaction chamber, for further purifying the UV purified air, and a post filter coupled to the air outlet.

  • Patent number: 8161579
    Abstract: A self contained battery energized apparatus is mounted within the water tank of a conventional flush toilet to eliminate malodorous gases. Air from the toilet bowl is drawn through the stand pipe in the toilet tank into a housing to expose the air to UV radiation to produce ozone molecules that have an oxidizing effect on organic matter and the UV radiation serves as a germicide and a virucide. The ozonated and oxidized gases are exhausted through a carbon filter.

  • Patent number: 8066940
    Abstract: Simultaneous application of ozone and ultraviolet light (UV185 and UV254) in water to be purified will create hydroxyl radicals, which combination will cause conversion of AS (III) that may be present to As (V), oxidation of inorganic matter such as manganese, sulfur, phosphorus and organic matter and provide virucidal and germicidal effects to purify the water.

  • Patent number: 8066941
    Abstract: A pressurized water tank having a head space includes a pump for recirculating the water through a nozzle disposed in the head space. The out flowing stream of water will entrain air and cause mixing of air entrained water with the remaining water in the tank. To enhance air entrainment and convey the air entrained water to a location well below the water level, the stream of water is injected into a vertical venturi tube. The entrained air will have an oxidizing effect upon organic matter and also cause circulation of the water within the tank. To enhance oxidation of organic and inorganic matter, a UV lamp may be located in the head space to convert oxygen molecules in the air into ozone molecules. Such ozone molecules would be entrained in the stream of water flowing out of the nozzle and into the tube and have a strong oxidizing effect upon organic and inorganic matter.

  • Publication number: 20110247972
    Abstract: An oxygen containing gas is injected at a pressure in the range of about two (2) to about five (5) atmospheres or more into an ultraviolet transmissive sleeve surrounding an ultraviolet lamp to produce a high concentration of ozone. Simultaneously, the ultraviolet lamp irradiates water to be purified disposed in a container surrounding the sleeve. The ozone enriched gas is entrained into the water flowing into the container resulting in an oxidative reaction with any organic matter present and coming into contact with the ozone. Alternatively, the ozone may be entrained in water in a second container downstream of the container wherein the water has been irradiated with ultraviolet radiation. In a further variant, the ozone may be entrained in water in a container upstream of the container wherein the water has been irradiated with ultraviolet radiation.

  • Patent number: 7794608
    Abstract: Water within a water tank is irradiated with ultraviolet light from a UV lamp for virucidal and germicidal purposes while simultaneously transforming oxygen molecules to ozone molecules in an oxygen containing gas flowing within an annular space defined by a sleeve surrounding the UV lamp. The ozone enriched gas flows into an enlarged chamber into which the UV lamp extends and the flow rate is reduced to enhance the time of exposure of the ozone enriched gas to UV radiation and thereby enhance the production of ozone. To increase the rate of transformation of oxygen molecules to ozone molecules, the gas is under a predetermined pressure prior to entering the annular space and subsequent to discharge from the chamber.

  • Publication number: 20080142452
    Abstract: A flow of oxygen containing gas is irradiated with UV light to convert oxygen molecules to ozone molecules and produce an ozonated gas. Water to be treated is augmented with silver prior to entraining the ozonated gas in the water. The ozone enriched water containing silver is irradiated with UV light to produce hydroxyl radicals. Whereby, microorganisms are killed by the UV radiation, organic matter is oxidized by the ozone and the combination of silver and hydroxyl radicals prevent downstream growth of bio-film contamination.

  • Publication number: 20070113327
    Abstract: Battery energized apparatus mounted within the water tank for conventional flush toilet operates in any or all of three phases of operation to eliminate odors. During the initial phase, air from the toilet bowl is drawn from the toilet tank into a plenum to expose the air to UV radiation to produce ozone molecules that have an oxidizing effect on organic matter and the UV radiation serves as a germicide and a virucide. During the flush phase, ozone enriched air is entrained in the water flowing into the toilet bowl. During the sanitizing phase, ozone enriched air is channeled from the plenum into the toilet bowl.

  • Patent number: 7033502
    Abstract: Each cap of a pair of end caps mounted on opposed ends of a conventional radial flow cylindrical filter element of a filter cartridge includes a circular sleeve extending axially from the filter element for penetrably receiving a supporting stud and for maintaining an O-ring seal therebetween. The area of one of the end caps radially outwardly of its circular sleeve is greater than the corresponding area of the other end cap to cause fluid to be filtered to pressure bias the filter cartridge toward the other end cap and to positionally retain the filter cartridge within its housing. A positioning member extending into the filter element from one of the end caps receives and stabilizes sleeve for a u/v lamp disposed within the filter element to kill any microorganisms present and to oxidize any organic matter subjected to the emitted ultra-violent radiation.
