Abstract
A propeller type aeration apparatus for inducing the flow of fluids into a liquid being treated by the rotation of a propeller in the liquid includes an outer housing having a hollow interior, and opposite first and second ends. A drive shaft is supported for rotary motion about its axis within the hollow interior of the outer housing. A motor is connected to a first end of the said drive shaft for rotating the drive shaft. A propeller is attached to a second end of the drive shaft and induces a flow of the liquid in which the propeller is disposed. At least one elongate conduit is attached to an outer surface of the outer housing. One end of the conduit is located adajcent to the propeller and in the path of the flow of the liquid caused by the propeller, and a second end of the conduit is in communication with a fluid to be injected into the liquid.
