ABSTRACT:
A method and apparatus are disclosed which provide enhanced solids-contacting vessel performance in a vessel in which untreated liquid is injected into a lower portion of the vessel so as to flow in a substantially helical and upward direct to separate the solids from the liquid in a suspended, rotating sludge blanket. The vessel is equipped with an adjustable weir extending substantially radially form the vessel center to its peripheral wall for withdrawing effluent from the vessel from a variety of locations depending upon the flow velocity characteristics of the liquid in the vessel.
