ABSTRACT:
A sparger (100) for producing gas bubbles in a liquid comprises a body member (102) having a gas inlet (105) and an outlet portion (106) provided with a gas outlet (108). The outlet portion (106) has an internal bore (110) which is in communication with the gas inlet (105) and the gas outlet (108). The bore (110) has opposite sides which converge in the direction of the outlet (108) to form a tapered region (112) in the bore (110). The bore (110) has a substantially constant diameter along at least a part of its length in an area between the tapered region (112) and the outlet (108). The sparger (100) further comprises a valve member (114) which is moveable into said tapered region (112) towards the outlet (108) for controlling the flow of gas through the outlet (108).
