ABSTRACT:
An air-driven rotary contact filter for biological cleaning of waste water has spiral channels mounted on a perforated rotatable center pipe having its axis of rotation disposed below the surface of the water whereby the filter is partially submerged with inlets to the channels at the central mixing chamber of the rotor below the water surface and some of the outlets at the periphery of the rotor above the water surface, so that when air is blown axially into the center pipe water is displaced on one side of the rotor whereby the channels will rotate due to the greater weight of water on the other side of the rotor.
