Sludge scrapers for circular tanks

Sludge scrapers for circular tanks

Finnchain has developed a special chain scraper system for circular sedimentation tanks, where collector chains move two or more bottom scrapers (and an attached surface skimmer when required) at the bottom of the tank. All the moving parts in the system are placed below the water surface, which protects them from freezing during winter. Keeping the parts below water also enables the easy covering of the tanks, and as the scraper rotates at the bottom, the covering can be attached to the tank walls. All the components in Finnchain’ system are made of corrosion-resistant fibreglass, plastic or stainless steel.
 
The system for circular tanks has several patented special features, such as efficient surface scum removal and a two-motor system for large tanks.Read more about the system in section ‘Innovated by Finnchain’.

Finnchain’s sludge scraper systems for circular tanks are being used in several sewage treatment plants. We installed four different sludge scraper systems to the pre-sedimentation tanks at Kozieglowy’ sewage treatment plant in Poznan, Poland. Currently, Kozieglowy’s cleaning capacity is 200,000 m3 water per day. Kozieglowy is one of the largest sewage treatment plants in Poland. A chain scraper system for circular tanks has also been installed at Mussalo's wastewater treatment plant in Kotka, Finland. Read more about our Kotka reference here.
 
Our goals in continuous product development include lower operating and maintenance costs, long service life of components, and saving time and the environment. The reliability, efficiency and long service life make our top-quality scraper system a rewarding investment.
