  • Aeration Devices For Treatment Of Activated Polluted Sludge (AREA)

Abstract

The invention relates to an aeration device for, for example, low-oxygen watercourses or waste water treatment plants, which aeration device consists of a propeller rotating under the surface of the water, turned by a drive device, and an air pipe through which air is fed into the water. The air pipe 3 is connected to the propeller 1 in such a way that the air which is fed into the water is released from the rear edge 10 of the blades 4 of the rotating propeller. <IMAGE>
