<p>Waste water treatment plant has a tank (10) with a bulbous lower portion (12) divided into upper (22) and lower (24) chambers by a partition (20). Waste water to be treated enters the lower chamber (24) via an inlet (28) and leaves the upper chamber via an outlet (44). While in the tank, the waste water is cycled periodically through biomass on plates (40) in the upper chamber (22) by injecting air from a blower (36) into the lower chamber to contact further biomass located on plates (34) therein.</p> |
