ABSTRACT:
Disclosed are a method and system for providing improved aeration of a fluid that is propelled though a pump to efficiently transfer oxygen and other gasses to a liquid body. In addition to the aeration, circulation of the liquid body may be performed to provide additional efficiency and benefit to the fluid system. In one embodiment, the apparatus performs efficient aeration by utilizing a venturi effect on the submerged intake manifold of a floating centrifugal pump. The aerated fluid is then directed to circulate the aerated liquid to a portion of the fluid body that is in greatest need of the gas that is being mixed with the fluid.
