Abstract
At least two levels of mixing, one adjacent the top of the vessel and one adjacent the bottom of the vessel are provided and individually driven at appropriate speeds to produce a single flow pattern in the fluid in the vessel. The bottom mixing apparatus is preferably a single large diameter impeller whereas the top mixing apparatus includes a plurality of smaller diameter impellers positioned equally distant from and symmetrical about the lower impeller's vertical axis of rotation. Each of the impellers have a converging flow field exiting the impeller.
