ABSTRACT:
A method and means for treating sewage using the activated sludge process. Sewage in a circular aeration chamber is given a spiral motion about the chamber centre and this motion is used to cause liquid-borne sludge to flow from the chamber along a canal around the chamber. Part of the sludge is returned from the canal to the chamber under the influence of gravity for recirculation.
