Abstract

In a flotation plant having a multiplicity of lamellae (2a, 2b, 2c) arranged parallel to each other, the invention proposes arranging the lamellae (2a, 2b, 2c) essentially vertically and arranging corrugated lamellae (2a, 2b, 2c) in such a manner that the corrugations run vertically and are offset relative to each other. A high degree of purification is achieved in the case of horizontal through-flow by highly polluted dirty water, since the unevenly broad flow paths for the water create zones in which the impurities to be floated can rise particularly easily. <IMAGE>
