Abstract

Air or another gas is introduced into a liquid or slurry stream flowing in a duct 1, 3 by means of a row of bubble generators 10 made of resilient and porous plastics material, e.g. high-density polyethylene. As shown, each generator 10 is a resilient hose extending transversely of duct 1, 3 and fed by the gas from inlet 6. <IMAGE>
