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.

Claim (Index 52):
An apparatus for treating air of an environment using a photocatalytic reaction, said apparatus comprising:\n a reactor bed including a plurality of media coated at least partially with a photocatalyst substance and a first plurality of ultraviolet light sources and a second plurality of ultraviolet light sources immersed within and substantially surrounded by said plurality of media, wherein a portion of said plurality of media resides substantially between a pair of ultraviolet light sources of said first plurality of ultraviolet light sources and said second plurality of ultraviolet light sources for receiving ultraviolet light from said ultraviolet light sources and for producing a plurality of hydroxyl radicals from a photocatalytic reaction of said photocatalyst substance induced by said ultraviolet light, wherein said ultraviolet sources are configured to produce said ultraviolet light having an irradiance greater than 5 \u03bcW/cm 2 ; an air-handling unit in fluid communication with said reactor bed and adapted to cause air to flow by and between media of said portion of said plurality of media, said air handling unit being in further fluid communication with said environment and adapted to cause air to be supplied to said environment after flowing by and between said media of said portion of said plurality of media; and wherein the first plurality of ultraviolet light sources are arranged substantially in a first single row extending in a direction of air flow, each of the first plurality of ultraviolet light sources having a longitudinal axis extending in a first direction such that the direction of air flow relative to the first plurality of ultraviolet light sources is substantially transverse to the first direction; wherein the second plurality of ultraviolet light sources are arranged in a second single row generally parallel to the first single row, each of the second plurality of ultraviolet light sources having a longitudinal axis extending in the first direction, wherein the first single row and second single row are arranged as baffles to the air flow; wherein respective adjacent pair of the first plurality of ultraviolet light sources and adjacent pair of the second plurality of ultraviolet light sources define an elongate volume including a portion of the plurality of media receiving ultraviolet light from each of the adjacent pair of the first plurality of ultraviolet light sources and the adjacent pair of the second plurality of ultraviolet light sources; and wherein said apparatus further comprises a sheath in contact with at least one media of said plurality of media and interposed between said one media and at least one ultraviolet light source of said plurality of ultraviolet light sources, said sheath is formed from a quartz material.
