ABSTRACT:
A motor rotated agitator is adapted to be inserted within a container of liquid wherein the agitator has a plurality of curved blades secure at their top edges to a disc adapted to be rotated by a motor. The lower edges of the blades have a circular plate secure thereto, having a central circular opening for input of fluid to inner ends of the blades. A sparge ring is disposed about the periphery of the agitator for ejecting a gas into output of fluid at the periphery of the agitator in an area spaced from the input area of the agitator, which is limited by use of the circular plate.
