Sand Water Seperator Grit Classifier for Wastewater Treatmment

Grit Classifier is also known as a grit screw, grit separator which are used at wastewater plants at the headworks (front end of the plant) to help separate the grit from organics and water. Grit removal needs to be done at the headworks of plants to help reduce wear to upstream pumps and mechanical equipment. Grit can also cause pipe blockage and reduce the effective volume of the treatment basins. Grit classifiers usually consist of a hopper positioned on top of an inclined screw conveyor. Typically grit classifiers are made of stainless steel housing and have a high strength abrasion resistant fights on the screw because of the abrasive application.

Working Principle
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 screw conveyorl. Effluent water evacuates through the top of the hopper to allow complete grit removal.


Our Advantages
Separation efficiency can reach 96 ~ 98%, and particles with a particle size of ≥0.2mm can be separated; shaftless screw conveyor, no bottom bearing, no consumables, reasonable structural design, no blockage, and low maintenance costs.
