ABSTRACT:
An apparatus for use in the biological treatment of contaminated water with activated sludge utilizing a sequencing batch reactor process, fixed film media reactor or the like and, in particular, for supplying oxygen rich gas to the proces. Air is located on one side of an oxygen permeable membrane under a differential pressure urging oxygen in the air to pass through the membrane for separating the oxygen from nitrogen in the air. The oxygen downstream of the membrane is conveyed by a gas line leading to a circulation manifold located in the reactor. Jet nozzles on the circulation manifold communicate with oxygen in the gas line. When activated sludge and wastewater are pumped into the circulation manifold and forced through the jet nozzles, a vacuum is created therein drawing the oxygen rich gas from the membrane into the nozzles and pumping the resulting liquid/gas mixture into the reactor, mixing the oxygen with the wastewater.
