Industrial grit classifier for wastewater treatment
Achieve efficient grit removal and sediment separation in wastewater streams with this robust solution, ensuring streamlined operations and reduced maintenance demands in your treatment process.

Separates and De-waters Grit from Wastewater
The GRITSEP DS Grit Classifiers from WAMGROUP offer a robust solution for separating and de-watering grit and sand from wastewater. Utilizing an inclined screw conveyor with a sedimentation hopper, this equipment excels in sedimentation by employing a low-speed, shaftless screw to convey and discharge de-watered solids efficiently. Ideal for industries ranging from municipal wastewater treatment to food processing and pulp and paper, the GRITSEP DS improves processing efficiency while reducing wear on subsequent equipment. With a liquid throughput of 5 to 36 m³/h and solids throughput of 0.06 to 0.36 dm³/s, it accommodates a wide range of operational needs. Constructed with stainless steel components and wear-resistant liners, the equipment ensures durability and low maintenance costs. Optional configurations such as vertical outlet and alternative motor protections allow for tailored integration into any production line. The GRITSEP DS is a sustainable choice, offering eco-friendly operation by minimizing energy consumption and eliminating the need for bearings.
