Abstract

1300724 Charging sedimentation tank DORR-OLIVER Inc 10 March 1970 [10 March 1969] 11349/70 Heading B1D In a sedimentation tank, the feed pulp is introduced via annular feed well 26 through pipes 29, 29a in opposed substantially tangential directions into feedwell 27 so that the influent energy is dissipated, and is distributed from well 27 uniformly in all radial directions while entering the surrounding body of liquid undergoing sedimentation.
