The present invention relates to an activated carbon sheet, and particularly relates to an activated carbon sheet for air purification comprising activated carbon, which is suitable for removing volatile organic compounds in the passenger compartment of an automobile or the like. An object of the present invention is to provide a sheet that is excellent in toluene adsorption capacity and flame retardancy. An activated carbon sheet for air purification comprising an activated carbon fiber, granular or powdered activated carbon, and a fibrillated fiber, wherein a mass (g/m.sup.2) of the activated carbon fiber is 5 g/m.sup.2 or more, a pressure loss as measured by a method set forth below is 150 Pa or less, and a burn distance as measured by the FMVSS 302 burning test is 51 mm or less: <pressure loss test method> the method is conducted in accordance with JIS B 9927:1999 “Appendix (Standard) Cleanroom—Air filters—Test methods”, 3.2 “Pressure Loss Test” as follows: a piece of the activated carbon sheet cut in the form of a circle with a diameter of 110 mm is used as a measurement sample; air is sucked though the measurement sample at a linear velocity of 0.1 m/s, and a difference in static pressure between an upstream side and a downstream side of the activated carbon sheet is measured with a differential pressure gauge; and figures up to the one's place of the measured value are used as significant figures.

The present invention provides a waste-liquid processing device, comprising: a first processing device and a mixing device, wherein the first processing device is provided with a first purifying unit for processing waste liquid from a waste liquid source to produce a purified liquid. The mixing device is used for mixing the purified liquid with a chlorine dioxide solution. The present invention also provides an air-pollution treatment device, comprising the waste-liquid processing device and a gas processing device. The gas processing device comprises an air extracting unit, a gas purifying unit, a gas-liquid separation unit, and an exhausting unit.

A system and method for maintaining, monitoring and improving air quality and purity in a room or environment, such as a hospital room or operating room.

A system for decontaminating/neutralizing breathable air and surfaces in an occupied enclosed space, i.e., hydroponic greenhouses, aircraft, rail and road vehicles, in building ducts, or rooms, includes mounting an atmospheric hydroxyl radical generator along an inside surface of an occupied space having respective air inlets and air outlets. The hydroxyl radical generator includes a polygonal housing supporting a plurality of spaced crystal-spliced UV optics medical grade pure quartz, which emit/irradiate ultraviolet in the nanometer wavelength/ultraviolet spectrum of between 100 and 400 nanometers for deactivating and neutralizing atmospheric chemicals and pathogens in breathable air and surfaces. The hydroxyl radicals contact the walls of the reaction chamber housing. The hydroxyl radicals become created and excited to react quickly with impurities including VOC, virus, bacteria and fungi, rendering them inactivated and neutral. The breathable air passes through the polygonal housing and is decontaminated and neutralized of impurities before entering the occupied enclosed space.

An air conditioning rotating body includes a rotor having a cylindrical shape, and a labyrinth seal structure. The rotor is housed in a casing so as to be freely rotatable. The air conditioning rotating body treats air passing through the rotor in an axial direction. The labyrinth seal structure is provided between an outer circumferential portion of the rotor and the casing. The labyrinth seal structure includes a first protrusion protruding in the axial direction from the rotor toward the casing, and a second protrusion protruding in the axial direction from the casing toward the rotor.

The present invention relates to a small, effervescent tablet for disguising bathroom odors. The tablet includes sodium bicarbonate, a mild acid and natural or essential oils. The tablet is wrapped in a moisture proof recyclable foil that can be torn along a perforation line to use the tablet. The tablet is simply dropped into a plumbing fixture and when the tablet is diluted in water, an effervescence is produced releasing carbon dioxide and the aroma of the natural oil is released to mask the unwanted odor. The packaging of an individual tablet is compact allowing a user to store and conceal the tablet in purses, waistbands, clothing, wallets, pockets, boots, and even in phone cases.

The present invention relates to a disposable container (100). The disposable container (100) is use particularly for vaporization, evaporation or diffusion whereby filler materials of filler means are released into the air flow stream through air flow means. The disposable container (100) comprising filler means (101) filled with filler materials within the closed empty space between an inner side wall (101a) and an outer side wall (101b) and a top (101c) and a bottom part (101d) of the disposable container (100); and locking means (104) at the bottom part of the disposable container (100) to further secure the disposable container (100) to an air flow means. The inner side wall (101a), the outer side wall (101b), the top (101c) and the bottom part (101d) of the disposable container (100) are permeable or perforated enabling filler materials to be released into an air flow stream through air flow means; wherein filler materials are released by means of vaporization, evaporation or diffusion.

A system for decontaminating/neutralizing breathable air and surfaces in an occupied enclosed space, i.e. building, aircraft, vehicle or greenhouse, includes mounting an atmospheric hydroxyl radical generator along an inside surface of the atmospheric hydroxyl radical generator having respective opposite air inlets and air outlets. The hydroxyl radical generator includes a polygonal housing supporting a plurality of spaced crystal-spliced UV optics, which are tubular, medical grade pure quartz optics to emit/irradiate ultraviolet in the nanometer wavelength/ultraviolet spectrum of between 100 and 400 nanometers for deactivating and neutralizing atmospheric chemicals and pathogens in breathable air and surfaces. The hydroxyl radicals contact the walls of the reaction chamber housing. The hydroxyl radicals become created and excited to react quickly with impurities including VOC, virus, bacteria and fungi, rendering them inactivated and neutral. The breathable air passes through the polygonal housing and is decontaminated and neutralized of impurities before entering the occupied enclosed space.
