ABSTRACT:
Apparatus for biologically treating sewage in an elongated circulation tank having a central partition extending along the longitudinal axis thereof thereby dividing the tank into two parallel flow channels connected together at opposite ends, aerators rotating about a perpendicular axis located along said longitudinal axis so that the sewage may be forced into a circulating flow about the perpendicular axis and about the partition. The circulating flow about said perpendicular axis thereby being decelerated and the sewage circulating about the partition being guided to and away from the rotating aerators with the full cross-section of the flow channels.
