Abstract
A system for biologically treating wastewater comprising a rotating drum disposed within a tank. Biofilm carriers are contained in the drum. One or more hollow tube aerators are secured inside the drum to a perforated wall that forms a part of the drum. As the drum is rotated within the tank, the mixing of the biofilm carriers with the wastewater therein and the action of the hollow tubes aerates the wastewater in the rotating drum.
