Scrapers with central drive for final sedimentation with logarithmic or straight scraper plates

We manufacture scrapers for final sedimentation with central drive to round and square final sedimentation basins. The operating gear is installed on a bridge above the basin or on the deck structure. Scraper blades attached to the centre shaft transport sediment to the sludge drain in the middle of the basin’s bottom. The scraper plates in the blades are shaped like a logarithmic curve, or they are straight plate blades installed at an angle. The clarified water is removed from the surface as overflow to the next process step. A surface sludge removal unit can be installed in the basin.
