GRIT REMOVAL MECHANISM

Detritor and Classifier Mechanism (screw/rake)

The grit removal consists of two essential elements- grit collecting mechanism and grit washing mechanism. Each operates separately but in hydraulic communication with each other. The removal of grit is essential to avoid heavy deposit in pipeline and abrasion of equipments.

Mechanism

The detritor is a continuous flow tank in which the grit settles due to gravity and the water overflows through the outlet weir on the opposite side. The settled grit is scrapped by means of a scraper mechanism towards the openings on the classifier sidewall at the bottom.
The collection chamber works on velocity principle and is so designed that only grit settles down and organic matter overflows. The classifier mechanism consists of a reciprocating rake/screw driven by a gear drive fitted with a motor. The grit collected is given a thorough washing and is delivered from the top of the classifier through a chute for further disposal. The Organic Return Pump/ Mixer returns the washed organic liquor lying in the classifier back to the detritor collection chamber.
