ABSTRACT:
A submerged aeration apparatus has a hollow shaft extending downwards from the surface of a body of liquid. The hollow shaft is used to transfer surface air or other gases to the body of liquid. An outlet for gas near the bottom end of the shaft is positioned below the surface of the body of liquid. An impeller connected to the shaft near the outlet for gas has an aperture adjacent the shaft for drawing liquid towards the impeller and circulating the liquid past the gas outlet for mixing the liquid with the gas, the impeller then expelling the liquid.
