Overhead scraper with suction

Home > Waste Water Treatment > Waste Water Treatment


The aspirated peripheral drive scraper bridge crane is a machine installed in sedimentation tanks in reinforced concrete with a circular base and a flat bottom. The power supply is of the radial type; the slurry to be treated is distributed from the center through the loading cylinder, while the clarified is removed through a Thompson-type perimeter surface spillway.
The sedimented sludge is conveyed to a collection tank with the combined aid of converging bottom scrapers and telescopic pumps or valves and siphon system. Any substances present in suspension are removed by a surface scraping blade, also anchored to the rotating bridge, which conveys it to a special collection tray.
