Peripheral Drive Sludge Scraper for Waste Water Treatment

Peripheral drive mud scraper is composed of service bridge, steady flow tube, scraper arms, scraper blades, overflow weirs, center supporting frame and driving unit.

The driving unit is installed at the end of bridge, walks on border of circle tank and scrape sludge while travelling.

Wastewater enters into clarifier through a "Central Steady Flow Tube", which is also called "Energy Dissipating Inlet and Feed Well", its function is to dissipate inlet water energy, steady water flow and distribute water flow uniformly.

Peripheral drive mud scraper is fitted with scraper arms and scraper blades that rotate in clockwise direction and thus convey the debris (sludge, etc.) towards the middle of the reinforced concrete tank(sludge discharge pit), from where sludge is discharged.

On request, the machine can be fitted with the suspended solids extraction mechanism, which thanks to the bridge rotation, conveys the foams (oily and light parts present on the water surface) to the scum trough fixed to the reinforced concrete tank wall. The clean water flows through the V-notched weirs and flows into the effluent launder.

This peripheral drive mud scraper is equipped with torque protection device, will shut down automatically once torque exceed set value to avoid potential damages.
