Abstract
An improved liquid aerating rotor assembly comprises a support frame having a rotor mounted for rotation about a horizontal axis. A plurality of floats support the rotor and support frame on the surface of a sewage pond or the like. A V-shaped deflecting plow or V-shaped front float is located upstream of the rotor. This configuration causes the upstream surface layer of liquid to pass around the rotor. This prevents any solid debris located in the surface layer of liquid from jamming the rotor and allows more complete aeration of sub-surface liquid. Alternatively, a scoop may replace the V-shaped deflecting members.
