Patent ID: 8337759

Claim:
An ozone-based system for reducing odiferous gasses emitted from a wastewater lift station, said system comprising a containment vessel containing liquid and gasses, wherein the level of said liquid changes over time, and the containment vessel includes a liquid inlet, a liquid outlet, and a liquid level pump configured to pump liquid from the containment vessel through the liquid outlet when the liquid is above a determined level in the containment vessel, and said containment vessel includes a vent in fluid communication with ambient air of an atmosphere, said ozone-based system comprising: a reaction chamber coupled to the vent, said reaction chamber comprising a gas outlet through which gasses flow to the atmosphere, said flow being induced by changing liquid level in the containment vessel, and a gas inlet fluidly coupled to the vent of the containment vessel, whereby, when the level of the liquid in the containment vessel substantially increases, gasses flow outward from said containment vessel flow through said vent and gas inlet and then through said gas outlet, and, when the level of the liquid in the containment vessel substantially decreases, ambient air flows inward through the gas outlet through said vent and gas inlet and then into the containment vessel, and a gas container fluidly coupling the gas inlet to the gas outlet, and at least one seal substantially sealing all openings in the containment vessel in fluid communication with ambient air, except for the vent, liquid inlet and liquid outlet, and an ozone generator operably coupled to a control system, said ozone generator being configured to controllably produce ozone and supply the produced ozone to the reaction chamber, and said control system controlling the production of ozone by the ozone generator based upon a determined parameter indicative of odiferous gasses emitted from the gas outlet.
