Rotating Scraper

Rotating Scraper’s main aim is to remove the settled sand, grit and suspended solids deposited at the bottom of circular settling tanks. They operate along the radius with an attached bridge sweeping across the bottom of the tank and also could be operated along with a skimmer for the scum at the top layer of the wastewater. Scraper moves radially along the diameter with guide wheels situated on the concrete walls. The scrapers could be pallet or suction type and if along with the bridge center or radial driven. They are designed according to the DIN 19569 and EN 12255 standards. These scrapers can be manufactured from Aluminum, Epoxy coated or galvanized steel or stainless steel.
