Abstract

Waste water is treated by the prolonged action of air, solar radiation and bacteria in a plant which comprises a circular settling tank with a conical base. A special feature is an annular and concentric aeration tank. An arm carrying rakes is supported at one end by a central concrete column while the outer end rests on rollers which run on a roller track. The arm rotates and the rakes bring the sludge to the centre for evacuation. The arm also carries a turbine which travels along the middle of the aeration tank. Water from the latter is fed to the centre of the settlement tank and the water, after clarification is extracted at the periphery in an annular overflow arrangement. Air injectors may be used instead of the turbine to agitate the water in the outer tank. The appts. is very compact and occupies far less space than existing plants; control and maintenance are therefore easier.
