After leaving the aeration basin, biologically cleaned wastewater and activated sludge enter final sedimentation. The role of final sedimentation is to separate the activated sludge from the water. Pump technology and scraping devices return sludge deposits to the aeration basin and send them for additional sludge treatment or for waste management. We manufacture and assemble the scraper bridge and suspensions to customer specification. All components made by suppliers come from well-known companies. We promise to perform proper and professional repairs rapidly if you find that the bottom scraper blade (seal) malfunctions during operation. A number of references pay testimony to our expertise and reliability. That goes for service and maintenance too.
