ABSTRACT:
A sewage treatment apparatus is disclosed comprising a tank (11) for receiving sewage effluent to be treated defining an inlet port (1) and an outlet port (8), compartmentalised so as to define a first sewage effluent settlement zone (3) below the level of the inlet port (1), a second sewage effluent settlement zone (7) below the level of the outlet port (8) and a trough compartment (14) such that the first sewage effluent settlement zone (3) is in communication with the trough compartment (14), and the trough compartment (14) is in communication with the second sewage effluent settlement zone (7); a first arrangement of substantially parallel baffle plates (16) disposed in the first sewage effluent settlement zone (3) between the inlet port (1) and the trough compartment (14); a rotating biological contactor (4) mounted for rotation in the trough compartment (14); a second arrangement of substantially parallel baffle plates (20) disposed in the second sewage effluent settlement zone (7) between the trough compartment (14) and the outlet port (8) whereby the arrangements of baffle plates are so disposed to promote a laminar flow of sewage effluent through the respective first and second sewage effluent settlement zones (3 and 7). A process for the treatment of sewage effluent is also disclosed.
