| abstract |
A gas bubble generator (1) for mixing or promoting turbulence in a liquid medium (2), particularly sewage or effluent, comprises a collector (3) for gas which collector is submerged in the medium (2) and has an exit (5) from which leads a pipe (4) with a curved part (9) between the exit (5) and a free end (8) of the pipe from which gas escapes as a bubble to surrounding liquid medium (2). The free end (8) is spaced laterally from the exit (5), and the curvature of the curved part (9) is 135 DEG so that there is no obstruction of the pipe (4) by the medium (2). |
