Ideal for the collection of high load sludge in industrial wastewater treatment plants. Apply robust and precious parts are applied.
Chain Flight Sludge Scrapers are made of structural steel, carbon steel and stainless steel for high loads of sludge removal in rectangular primary and secondary sludge settling tanks. It provides higher sludge removal efficiency than any other scraper mechanism due to metal flights installed. In the view of high loads of sludge removal, space of installation, power consumption, and long duration of operation, the most economical scraper system is chain flight sludge scraper system. 2.2 to 3.7 Kw motors with cycloid reducer or geared type reducer are applied. The system is consisted of drive units, sprockets, flights, flight attachments, shafts, tension units, guide rails, bottoms rails, tension units, scraper chains, drive chains, and others.
DWA Fabricated & supplied 20 units of chain flight sludge scrapers to a WWTP, Steel Mills in Istanbul, Turkiye in 2010.
