In-line Aeration System Provides Required Level of Dissolved Oxygen in Pressurized Effluent Line_PIX

The treated effluent from all wastewater treatment plants across the country must meet local dissolved oxygen (DO) limits before discharging into receiving waters. A municipal WWTP in southern Mississippi has a pressurized effluent line to discharge into a local river. Since the line is pressurized, the standard method for increasing DO, a cascade (aka waterfall), was not a valid option. Read the full case to find out what option worked.
