Abstract
An apparatus for ingesting and mixing gas into a liquid body includes a tank, a rotatable impeller fixed to a vertical drive shaft, and a vertically-extending conduit which surrounds the drive shaft and which extends to a location in the liquid above the impeller to serve as a channel of communication between a source of gas and the impeller. In the conduit, a vortex-turning baffle having an enlarged gas-flow aperture formed centrally therethrough is fixedly mounted above the impeller so that when a rotor-induced liquid vortex rises along the wall of the conduit, the vortex is turned downwardly by the baffle to aid in the ingestion of gas into the liquid.
