Circular grit separator for wastewater treatment
In wastewater treatment facilities, the efficient removal of grit is crucial to prevent damage to downstream equipment and reduce maintenance needs. High flow conditions can make grit separation challenging, demanding robust and efficient solutions.

Efficient grit removal from sewage
The Circular Grit Trap DSP by WAMGROUP is designed to remove sand and grit from sewage in wastewater treatment plants. Featuring a drive unit with a central bearing, two steel blades, and a central air lift pipe, this system ensures efficient settlement and removal of grit. The tangential entry of sewage into the concrete tank and the rotational movement facilitated by the blades allow the sand to settle at the bottom. Compressed air powers the air lift, lightening the sand-water mixture and effectively extracting sand from the tank bottom. Available for tanks up to 6 meters in diameter, the DSP Grit Trap is constructed from robust carbon steel hot dip-galvanized or stainless steel (304 L / 316 L), ensuring durability and low maintenance costs. Suitable for various industrial applications, including municipal wastewater treatment, tanneries, dyeing works, and fruit & vegetable processing wastewater.
