GRITSEP - Grit Separators

Project Description

Description - The GRITSEP DS Grit Classifiers consist of an inclined screw conveyor with a large volume hopper including an inlet spout and a water outlet spout, a shaftless screw housed in a trough, a low friction anti-wear trough liner, a trough cover, an outlet spout for solid particles, and a drive unit mounted at the outlet end.

Function - Water to be cleaned flows through the inlet spout of the GRITSEP Grit Classifier into the decantation hopper where sedimentation of the solid particles is taking place. The low screw rotation speed improves sedimentation and sees to conveying and discharging of de-watered material through the upper outlet. Cleaned water exits through the lateral hopper discharge spout.
