ABSTRACT:
The improved apparatus of the present invention functions to substantially concentrate, separate, and remove floating solid materials from the surface of a volume of liquid. In preferred embodiments, the apparatus functions in two stages. In the first stage, the apparatus is directed to a treatment volume that is disposed adjacent an untreated volume of liquid. An entry means is disposed therebetween for flow of the surface portion of the untreated volume thereover. A baffle is disposed across the treatment volume and extends to a depth beneath the surface to permit the flow of the liquid thereunder, but to entrain the flow of solids material and to channel the flow of solids material into a take-off chamber over a take-off weir. In the second stage of the concentrating, separating, removing apparatus of the present invention, an influent flow of solids containing liquid is directed horizontally across and near the surface thereof to accumulate a sludge on the surface of the volume. The accumulated sludge is then removed from the surface, and effluent is withdrawn from the bottom portion of the treatment volume, and returned to the source, such as a spray booth header.
