Eductor apparatus (100, 99) is provided for introducing gas into a liquid in a gas flotation cell, the apparatus comprising a clean liquid inlet port (101), the inlet port having an outlet end (104) through which the clean liquid is ejected in a first direction, a gas inlet chamber (187) adjacent to the outlet end of the inlet port for introducing gas to the liquid from a gas inlet port (102), the gas inlet chamber substantially surrounding the flow of liquid when the apparatus is in use, and a gas/liquid mixing and diffusing section (103) wherein gas is entrained within the liquid prior to being ejected from the eductor apparatus into the contaminated liquid, the gas/liquid mixing and diffusing section having a direction of fluid flow substantially transverse to the first direction such that the fluid exits from the gas/liquid mixing and diffusing section substantially radially outwardly relative to said first direction. |
