ABSTRACT:
A method of aerating slurry involves the use of a screw conveyor operating in a tubular casing having an inlet and an outlet. The inlet has access to the air above the level of the slurry so that as the conveyor is rotated air is admitted through the inlet and discharged at the outlet, which is below the surface level, into the body of the slurry. The screw conveyor may be in two portions of opposite hand so that one portion discharges air and the other portion discharges slurry at a common outlet intermediate the two ends of the casing.
