Abstract
A system and method for inhibiting and precluding the buildup and offgas of offensive odors and corrosive sulfuric acid in wastewater in a variety of locations in a sewage system through the use of superoxygenation. The system comprises an oxygenator having an inverse conical section for a downward flow of oxygen gas injected into the sewage stream prior to entering the oxygenator. In one embodiment, the system is inserted directly into the main sewage stream, while in another embodiment, the system is used to treat a sidestream from the main sewage stream.
