C A N A D A Title: LIQUID TREATMENT APPARATUS Inventor: LEONARD SYDNEY LOVE ABSTRACT OF THE DISCLOSURE The disclosure relates to a liquid treatment apara- tus which includes a clarifier tank and an integral sludge thickener tank. Liquid enters the clarifier tank through an inlet member disposed generally centrally of the bottom wall of the member and passes upwardly through an eductor member into a mixing zone defined by a reaction cone. Recir- culation of liquid and suspended particles below the cone pro- motes flocculation of those particles. Gravity settling also takes place in the relatively quiescent area outside the cone. The liquid inlet member is of divergent cross-sectional shape for dissipating some of the energy in the liquid and a vari- able speed rotary impeller is disposed in the inlet and can be adjusted to control liquid circulation according to the flow rate of influent liquid. The apparatus also includes an integral sludge thickener tank to which sludge and liquid are continuously delivered from the clarifier tank. Clari- fied water from the thickener is returned to the clarifier tank and the effluent from the thickener tank is discarded.
