  • Publication number: 20060144690
    Abstract: The present invention is a high volume, wall-mountable air sanitation apparatus for disinfecting and removing VOC's with high energy UV light and ozone. The apparatus has a powerful fan and an elongated UV light source and target for use with the movement of a large volume of air. The target includes a mesh and a secondary target both comprising a target compound which creates hydro-peroxides, super oxide ions and hydroxyl radicals in the presence of water also for removing pollutants in the air.

  • Publication number: 20040056201
    Abstract: This invention is a modular, adjustable, easy to maintain, portable food sanitation hood system, comprising a hooded means for subjecting food to sanitizers including UV light, ozone and hydroxyl radicals, and a method for using the system. The means for subjecting food to the sanitizers includes one or more UV radiation sources and one or more target rods for UV radiation located under a hood. The UV radiation sources are preferably low-vapor mercury UV light sources that emit UV light of approximately 185 to 254 nm. The hood preferably includes an adjustable light curtain to at least partially reduce radiation emitted away from the food. The target rods comprise up to approximately up to 0-30% titanium dioxide, up to 0-30% silver and up to 0-30% copper, by weight. The system may include a mister for adding mist in proximity to the food for efficient sanitization.

  • Publication number: 20040016887
    Abstract: A compact, efficient, easy-to-maintain enclosable cabinet for sanitizing a liquid flowing along a cascade within a cabinet body, having a cabinet body, a plurality of troughs directing the liquid along a predetermined path including a cascade within the cabinet body and one or more sanitizing radiation sources for subjecting the liquid to a sanitizing radiation for a predetermined time while flowing along the predetermined path, whereby the liquid is subject to sufficient sanitizing radiation for a predetermined level of sanitization. The sanitizing radiation sources are assemblies having a UV light source, a UV light shield located between the UV light source and the liquid and a rigid internal reflector shield located between the UV light source and the UV light shield.
