Description

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.
