ABSTRACT:
Apparatus and methods for continuous sedimentation-type separation of solids from liquids of a feed slurry in a thickener-clarifier-type tank operated by overflow removal of clarified liquid and underflow removal of a concentrated underflow slurry by using a flocculant in a zone of intense mechanical agitation provided by a rotatable impeller rotated at tip speeds of between approximately 300 to 600 feet per minute to produce relatively small, bead-like floccules directly above the concentrated underflow slurry.
