<p>Waste water submerged oxygenation pipe oxygenates waste water held in a basin by a submerged tubular assembly discharging air into the water. The tube (1) is surrounded by a perforated membrane (2) which when not dilated by the pressure of gas (3) hugs the tube, preventing ingress of water into the tube chamber (3). When the air in the chamber (3) is pressurised, the membrane (2) partially lifts clear of the tube (1) surface. The the gas (3) pipe (1) may be extended in length as required. The gas pipe (1) incorporates a gas inlet (4), gas outlets (5) at intervals along its length and (7) a drain hole (7) for condensate.</p> |
