ABSTRACT:
A self-diluting feedwell for a thickener or settling tank includes a delivery pipe for providing an influent feed stream of slurry, a nozzle for directionally discharging the influent feed stream, and an eductor structure including a launder zone for receiving the nozzle discharge, a throat zone for creating a reduced pressure area for eduction of diluent into the launder zone, and a discharge zone for dispensing the diluted influent into a thickener or settling tank.
