ABSTRACT:
Apparatus for concentrating solids from a solids/liquid mixture, particularly sludge from a waste stream/flocculating polymer mixture, includes a frusto-conically shaped drum. A solids/liquid mixture is introduced through a conduit into a large end of the rotary driven conical drum. A maximum amount of the free liquid in the mixture is released from the drum through its screen side wall near the large entrance end of the drum. The solids in the drum, after initial release of the liquid therefrom, are moved during their travel to the smaller exit end of the drum where the surface movement of the drum is slower. The resulting thickened or dewatered solids are removed from the smaller end of the drum as a formed cake or in the form of thickened sludge.
