Abstract: Wastewater treatment and conveyance; and other chemical processes result in emission of a wide variety of odorous compounds. Contaminated exhaust air is typically a byproduct emitted from sludge in tanks and wells that are part of a wastewater treatment, conveyance, or chemical process. Said contaminated air has to be treated to capture or reduce odorous compounds or pollutants below human smell recognition threshold levels before the exhaust is discharged to the atmosphere. The present invention is a carbon scrubber used to treat and filter contaminated exhaust air produced in wastewater treatment and conveyance; and other chemical processes.

Abstract: In order to elevate dust collecting efficiency by improving a suction work efficiency of a water filter type vacuum cleaner, an air containing dust particles sucked through a sucking opening by virtue of a motor driven blower provided built in a casing of the vacuum cleaner is caused to strike against water previously placed in a water tank to capture inappropriately large dust particles by the water. Moreover, other dust particles pass through a wire netting and then, are sucked together with the water to the blower by channeling the dust particles and water through a suction duct communicated with the blower. The dust particles contained in the sucked air are completely captured by the water by stirring the air and water at a high speed rotation of the blower, and the air and water are then conveyed into the water of the water tank. In the water tank, bubbles are generated by a bubble generating filter to naturally separate the water and the air, whereby clean exhaust air is provided.

Also included is a perforated separating diaphragm submerged in the water, and a first removable funnel shaped deflector means placed in an almost suspended position inside the tubular jacket above the water level.

Abstract: A versatile waste disposal apparatus for separating and disposing the liquid waste from vacuum cleaning of soiled carpets. The air, liquid and accumulated dirt in a mixture from a conventional vacuum cleaner are separated in one large tank, and the filtered liquid is passed on either to an integrated or non-integrated smaller tank with cutoff, air venting, and pump controls. The filtered liquid is ultimately passed on to a wastewater system so that the tanks are empty after use. The waste disposal apparatus can be integrated with a dwelling's central vacuuming system and operated on house current. The apparatus can be installed in a vehicle and powered by the vehicle's battery.

Abstract: An improved process and apparatus are provided for recovering hydrocarbons from an intermittent or continuous inlet air-hydrocarbon vapor mixture. The air-hydrocarbon vapor mixture is caused to flow through a bed of solid adsorbent whereby hydrocarbons are removed therefrom and a residue gas stream of substantially hydrocarbon-free air is produced. The substantially hydrocarbon-free air is vented into the atmosphere and a second bed of solid adsorbent having hydrocarbons previously adsorbed thereon is regenerated by evacuation. As long as the concentration of hydrocarbons contained in the vented air is below a predetermined concentration, the inlet air-hydrocarbon vapor mixture is caused to continue to flow through the first bed of adsorbent. After the second bed of adsorbent is regenerated, the pumping and evacuation of the second bed is shut down and not restarted so long as the monitored concentration of hydrocarbons is below the predetermined concentration.
