ABSTRACT:
A flotation cell for removal of solid particles contained in a liquid has, upstream of its inlet, a mixing chamber providing a passage through which the liquid passes to the cell inlet and in which the liquid is charged with air or other gas to form bubbles therein. This chamber is provided with at least one pair of opposed, converging walls extending across the passage to form opposite faces of a liquid flow path to a restricted gap between these walls at their greatest convergence, and so arranged that substantially all the liquid flowing through the chamber is forced to pass through such a flow path. Gas injection means provides a flow of gas under super-atmospheric pressure into the liquid flowing between these walls in the vicinity of the restricted gap between them to form bubbles in the liquid distributed across the path of flow.
