ABSTRACT:
An aerobic bacteria sewage treatment apparatus for treating waste water mixed with activated sludge by circulating the mixed liquor about a clarification compartment placed in a main treatment tank from which the clarification compartment withdraws water at a quiescent zone and further separates out and filters solid matter, finally delivering a well clarified effluent withdrawn from the top of the clarification compartment, the apparatus having an auxiliary digester compartment operative to periodically receive a proportion of the contents of the main tank, which contents are treated and allowed a time to settle out solids, whereupon the clear water from the auxiliary compartment is returned to the main treatment tank and the solids are left to accumulate for further treatment and later removal, the transfer of said proportion of the mixed liquor from the main tank being accomplished by overflow resulting from a purge cycle during which the clarification compartment is back-flushed into the main treatment tank.
