Abstract

An improvement for the aeration of the water and combining the aeration with the cleansing of the water by a biological cover, in which one or several circular disks rotate in a clarifying reservoir about a horizontal shaft. These carry at their circumference annularly bent funnels which extend in part above the water surface and continuously converge in direction from the inlet opening to the outlet opening. Above the water surface air enters through the inlet opening into the funnel and below the water surface water enters into it. Because the funnel converges continuously, both water and air are accelerated and compressed in the funnel. The compression assures that the amount of oxygen which is soluble in the water and can be accepted by the same from the air, is substantially increased. The biological cover forms on the disks and on the outer surface of the funnel.
