Abstract

An apparatus for removing gas from a liquid such as sewage comprises a siphon having a rising leg 2 arranged coaxially within a falling leg 3. Depending into the siphon from a closure member 4 is a skirt 5. A gas extraction pump 6 is in communication with the siphon by means of a tube 7 which extends through closure member 4 at a location outside the skirt 5. Any foam drawn through with gas in the liquid when the pump 6 is operated will have to pass through liquid since the vacuum is drawn from the pump 6 at a location outside the skirt 5. <IMAGE>
