ABSTRACT:
A mixer comprising a rotary driven conical drum into a large end of which sludge and flocculating polymer are introduced, constitutes a contact chamber, and is equipped with baffles and weirs. The sludge and polymer are 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 chamber is then discharged through a conduit into any of various types of dewatering devices such as sludge bags, sludge strainers, sludge presses, etc.
