Abstract
A tank with a generally flat, rectilinear bottom wall receives raw water for clarification by flotation. An array of lamellae define a set of generally vertically oriented channels. Flotation occurs in each channel. The channels are preferably inclined. A pair of endless chains or the like rotate alongside the tank to move a succession of mutually spaced, paddle-like lamellae through the tank. Sliding seals secured to the edge or edges of the lamellae isolate individual channels, or groups of channels, as they move through the tank. The channels lock and move a column of water through the tank with substantially no turbulence.
