ABSTRACT:
This invention relates to the mixing of gases with liquids and particularly aeration of predominantly water based liquids. The invention provides an apparatus for promoting gas/liquid exchange in a liquid impoundment in which a riser tube is disposed vertically in the liquid. Flow of the liquid up the riser tube is promoted by introducing gas bubbles into the liquid inside the riser tube. The riser tube has a baffle or restrictor giving rise to a region of fast flowing liquid in the riser tube and the bubbles of gas are introduced in the region of fast flowing liquid, the arrangement is such that the baffle or restrictor causes an abrupt change of velocity and hence turbulence as the liquid flows upwardly in the riser tube past the said baffle or restrictor.
