GRITSEP DS ensures efficient separation of grit or sand from waste water through decantation and removal by means of a conveyor screw.

---

GRITSEP DS Grit Classifiers consist of an inclined screw conveyor with a large volume loading and sedimentation hopper including a water inlet and 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 DS Grit Classifier into the decanting hopper where sedimentation of solid particles takes place. Low screw rotation speed improves sedimentation and sees to conveying and discharging of de-watered grit and sand through the upper outlet. Clean water exits through the side discharge spout of the hopper.
