Grittec Grit Classifier


Grittec is a grit classifier that separates rock, sand, and grit from screened wastewater. A large surface tank allows screened material to settle to the bottom, where a shaftless screw conveys screened debris to a dumpster.

The grit removal system operates by decantation to remove grit, sand, and rocks. Influent water flows slowly into the inlet hopper to allow grit to settle at the bottom of the tank. Then, captured grit is conveyed upward by the shaftless spiral. Effluent water evacuates through the top of the hopper to allow complete grit removal. A spray bar and cyclone system is optional.

A deep, wide tank allows efficient grit classification.
