Abstract: A photocatalytic air treatment system, including apparatuses and methods, for killing and/or mineralizing bacteria, viruses, mold, fungi, spores, mycotoxins, allergens, and other similar microorganisms or agents, and for oxidizing volatile organic compounds (VOCs). The system comprises one or more reactor beds configured in one or more stages with each reactor bed including a plurality of photocatalyst coated media substantially surrounding a plurality of sheathed ultraviolet light sources that may be arranged in a plurality of configurations. Adjacent ultraviolet light sources are positioned so as to create killing zones of photocatalyst coated media therebetween that are irradiated with ultraviolet light from multiple sources and in which an increased number of hydroxyl radicals are present. The photocatalyst generally comprises titanium dioxide, but may include one or more enhancers. The media is formed from or is coated with a material that induces the photocatalyst to form a nano-particle structure.

Abstract: A discriminating humidification system for humidifying a controlled space which, in its most preferred embodiment, includes a control device connected to a water source for supplying water at a constant pressure, a tubing network for transferring water from the control device, a mist nozzle located within the controlled space and connected to the tubing network to receive water transferred from the control device, and a droplet discrimination device positioned around the mist nozzle and located within the controlled space for removing and draining larger water droplets from the mist sprayed from the mist nozzle for releasing a very fine water mist into the controlled space outside the droplet discrimination device.

Abstract: A misting system is constructed of plastic pipe having a square cross-section, the pipe being dark inside and light outside so that the outside matches the counter and the inside absorbs ultra violet light. The plastic pipe is drilled and threaded to receive nozzle assemblies where needed. Each nozzle assembly includes a valve, and two angled branches, the branches being rotatable about the assembly while the nozzle branches are rotatable about their axes. The square pipe includes fittings for directing the pipe as required, and mounting brackets for mounting the pipe. The brackets are clevises that receive the pipe therein, and include keepers for securing the pipe.
