ABSTRACT:
An apparatus for gas bubble flotation comprises an angular flotation tank (1a, 1b), at least one liquid inlet (2a, 2b) for a liquid containing suspended matter and a liquid admixed with gas bubbles, in which apparatus at least one liquid inlet (2a, 2b) is arranged in the vicinity of at least one flotation tank corner. Preferably, the flotation tank has a square cross section. This permits optimal utilization of the available space, and results in a continuously decreasing flow velocity and thus an improved flotation effect.
