Abstract

Oxygenation appts. for activated sludges, is intended for use in the biological purificn. of waste water ans sewage, it consists of at least one cylindrical chassis which rotates, at a low speed, around a horizontal axis whilst partially immersed in a puricn. tank. The cylinder has at least one layer of light% prefabricated elements around its periphery, they are open at their ends and form conduits in which the air or the oxygenated gas accumulates during the passage of the elements through the atmos. The cylinder is turned by the motor at a max speed of 5-50 cm per second at its periphery, it is partly immersed in the tank which has an inlet for the raw water and the recirculated sludge, and an outlet for the purified water. As the cylinder rotates, the elements are progressively immersed and the air accumulated in the conduits is evacuated in the form of bubbles. Appts. is easily maintained and there is no difficulty in replacing defective elements.
