The drive unit rotates the sludge scraper around the center of the sedimentation tank. After the raw water is settled in the tank, the clarified liquid is discharged from the overflow weir plate. The sludge settled at the bottom of the tank is slowly moved towards the central mud collection channel along the bottom, propelled by the push of the logarithmic spiral scraper plates, and then discharged through the mud discharge pipe. Simultaneously, the floating scum accumulates in the area between the scum scraper and the scum baffle. As the working bridge passes over the floating scum discharge tube on the surface of the tank, the scum discharge tube is pressed below the liquid level, and the scum is discharged out of the tank through the discharge tube.

1. The scraper is designed with a logarithmic spiral curve and supported by rubber wheels to glide along the pool bottom, offering excellent sludge removal with minimal requirements for the pool's base.

Adaptable.

2. In addition to the main mud scraper, a unique auxiliary mud scraper is also installed, enabling the semi-bridge mud scraper to function like a full-bridge mud scraper.

3. The working bridge is designed with a truss structure, featuring a steel grating deck for high strength, light weight, and energy-efficient performance.

4. The drive wheel is a solid rubber wheel, requiring no track, with a simple structure and easy installation.

5. Submerged components are made of stainless steel, while above-water parts are constructed from carbon steel with hot-dipped galvanizing, offering excellent corrosion resistance and a long service life.
