Grit Classifier – GRITSEP DS

Inquip distributes Grit Classifiers that ensure the efficient separation of grit or sand from waste water via decantation through screw conveyors.

Speco GRITSEP DS Grit Classifiers

The GRITSEP DS Grit Classifier consists of an inclined screw conveyor with a large volume decanting hopper for sedimentation 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.

Water to be cleaned flows through the inlet spout of the Classifier into the decanting hopper where sedimentation of the 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.
