Peripheral Drive Sludge Scraper for Waste Water Treatment
Central Drive Sludge Scraper
Sludge Scraper is also called clarifier scraper or bridge scraper, is a machine which scrape, collect and discharge sludge in round primary sedimentation tank, secondary sedimentation tank and sludge thickening tank; Standard products working diameter ranges from 4m to 20m.
Wastewater enters into sedimentation tank through the central Water Flow Stabilizer, 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. Central drive sludge scraper is fitted with a central shaft with scraper arms and scraper blades that rotate in clockwise direction and thus convey the debris (sludge, etc.) towards the middle of sedimentation tank to the central sludge discharge pit, from where sludge is discharged.

Details
Central Driving perfectly solved the problems of clarifier edges leveling as well as driven trolley skidding in winter conditions.
On request, this 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 sedimentation tank wall. The clean water flows through the V-notched weirs and flows into the effluent launder.
