Sewage oxygen enrichment in sewage and industrial waste - using recirculating tube system with an inner membrane hose to disperse oxygen into the flowing aq. medium

摘要

In a process to enrich an aq. medium with gas, and esp. oxygen dispersed into the fluid through a membrane tube, the medium travels in a closed circuit where the gas is introduced. The medium is contained within the recirculating circuit until the required gas, and pref. oxygen content level is achieved and then passed out of the circuit. Pref. the aq. medium is recirculated through the circuit by a pump, and the amount of oxygen enrichment is set by the length of the closed circuit, or through the ratio of the membrane hose vol. and the closed circuit vol. USE/ADVANTAGE - The method is for increasing the oxygen content in sewage and industrial waste, esp. from paint mfg. and seepage water from rubbish dumps.
