Sand Water Gravel Classifier Grit Separator SS304 Wastewater Treatment Plant Grit Removal

Sand Water Gravel Classifier Grit Water Separator For Wastewater Treatment

Product Overview

The Grit Separator (Grit Classifier) is a key device used in wastewater treatment systems to separate sand, grit, and other heavy inorganic particles from water. It effectively reduces wear and damage to downstream equipment such as pumps, clarifiers, and sludge treatment units. This equipment ensures the stable operation of the entire wastewater treatment process by removing abrasive particles early in the process.
Working Principle

The wastewater containing grit flows into the grit separator. Under the influence of gravity, the heavier particles such as sand and gravel settle to the bottom of the tank, while the lighter organic matter and water flow out. The settled grit is conveyed by a screw (or scraper) to the discharge outlet, where it is dewatered and discharged, achieving efficient grit-water separation.
Main Components

• Separation Tank: Stainless steel structure designed for grit settling and separation.

• Screw Conveyor: Transports settled grit from the bottom to the outlet and performs dewatering.

• Drive Unit: Includes motor and gearbox to power the screw.

• Water Inlet and Outlet: Optimized flow design ensures stable hydraulic performance.

• Control Panel (optional): Provides automatic control of operation and overload protection.

Features

• High separation efficiency and low organic content in discharged grit.

• Compact design with easy installation and maintenance.

• Corrosion-resistant stainless steel construction (SS304 / SS316 optional).

• Energy-saving operation with low power consumption.

• Customizable size and screw inclination angle according to project requirements.

• Optional automatic control system for continuous operation.

Applications

• Municipal wastewater treatment plants

• Industrial wastewater treatment systems

• Slaughterhouses and food processing plants

• Paper mills and chemical plants

• Pretreatment systems for sewage pumping stations
