Abstract:
A method of oxygenating liquid sewage, comprising the steps of:forcing a jet of gas comprising oxygen from a source opening;forcing a liquid into a pressure chamber which chamber surrounds the source opening, the pressure chamber having an exit orifice positioned downstream of the jet of gas exiting the source opening;wherein the source opening and pressure chamber exit orifice are positioned such that the liquid surrounds the jet of gas and forms a stable cusp at the interface between the gas and the liquid, thereby forming a stable microjet of gas, and the gas microjet surrounded by the liquid is caused to move out of the exit orifice into liquid sewage and further wherein the microjet undergoes acceleration based on an abrupt pressure drop on passing through the pressure chamber exit orifice.
