A method for treating a liquid wherein the liquid to be treated is caused to flow through a tank equipped with at least one electrode assembly in the base thereof for the generation of gas bubbles by electrolytic action, whereby suspended materials, usually but not necessarily solids, in the liquid are carried to the surface of the tank by said bubbles to form a layer of thickened material, characterised by the step of dissolving air under pressure into the liquid before it is caused to flow through said tank, whereby the amount of gas available for flotation purposes exceeds that available from the electrolytic action alone. |
