We manufacture sludge thickener scrapers with central traction to round and square 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 sludge to the sludge drain in the middle of the basin’s bottom. The straight scraper plates are installed at an angle.

The clarified water is removed from the basin as overflow to the beginning of the purification process. Rake-type bars are installed vertically on the scraper blades to prevent the formation of a vertical sludge bed in the middle of the basin.
