ABSTRACT:
Apparatus for treating waste water by the solids contact aerobic biological treatment process comprises a clarifier and a reaction basin in liquid communication with one another. In one embodiment, the reaction basin has an aerator which also circulates liquid through the clarifier by way of pipes arranged to collect liquid from the surface of the reaction basin and deliver it to a location adjacent a back wall of the clarifier. The clarifier has a bottom wall which slopes towards the reaction basin. Sludge particles in the liquid settle out in the clarifier and liquid discharged from the pipes flushes the settled biological sludge back into the aeration section of the reaction basin. In another embodiment the clarifier and reaction basin together form an oxidation ditch defining a closed loop. An aeration device continuously circulates liquid around the loop and through the clarifier.
