ABSTRACT:
An aerator for bodies of water comprises a submerged water intake with a filter on it, that leads to the axial inlet of a centrifugal pump of the type that can handle substantial quantities of air. An air inlet to the axial pump inlet introduces the air centrally into the pump chamber, where it is admixed with water and discharged from a peripheral outlet to a point beneath the surface of the water. The pump can be of the type that has a rotor with a plurality of vanes of airfoil configuration.
