ABSTRACT:
A rotary driven conical drum into a large end of which sludge and a flocculating polymer are discharged, constitutes a contact chamber, and is equipped with baffles and weirs. The polymer is supplied to a large end of the drum and mixing is accomplished in the large end of the drum where the surface area of the drum is moving most rapidly. Thereafter the mixing action is slowed down by travel of the mixture to the smaller end of the drum, where the surface area of the drum is moving more slowly, to build up the flocs. The sludge/polymer mixture produced in the contact drum is then discharged through a conduit into the large end of a rotary driven conical concentrator drum. A maximum amount of the free water in the mixture is released from the concentrator drum through its screen side wall at the large end of said drum. The flocs remaining in the screen drum, after initial release of the water therefrom, are protected by their travel to the smaller end of the drum where the surface movement is slower. The resulting thickened or dewatered sludge is removed from the smaller end of the concentrator drum as a formed cake.
