Circular grit separator for wastewater treatment

Efficiently separates grit from wastewater, enabling clean discharge and reducing maintenance issues downstream. Ideal for consistent water treatment performance in your facility.

Efficiently Removes Grit from Wastewater

The Circular Grit Trap DSP from WAMGROUP is designed for efficient grit removal in municipal and industrial wastewater treatment. It operates with a central bearing and two steel blades driven by an impeller, enabling sand to settle while ensuring separation efficiency even with high flow rates. The DSP uses a circular motion to direct sediments to the tank bottom, where a central air lift pipe, powered by compressed air, raises the sand-water mixture for extraction.

Ideal for applications in municipal facilities, industrial plants, and specific industries like fruit and vegetable processing and tanneries, this system effectively processes diverse wastewater types. With the flexibility to fit tanks up to 6 meters in diameter and options for carbon steel or stainless-steel construction, it ensures durability and resistance to corrosive environments.

Installation in existing tanks is straightforward due to its modular design. Low maintenance requirements and robust construction make the DSP a cost-effective solution for continuous operations. Customizable with alternative voltage, frequency, and motor protection levels, it can integrate seamlessly with your facilities’ existing infrastructure.
