ROTAMAT® Disc Thickener RoS 2S

Unique sludge thickener for efficient sludge treatment

For wastewater treatment plants up to 200,000 PE

The heart of the RoS 2S Disc Thickener is an inclined, slowly rotating filter disc that separates flocculated sludge from filtrate. A baffle plate distributes the inflow from the flocculation reactor evenly across the entire filter radius. Flexibly supported plows divide and move the sludge layer on the disc and open up furrows so that water can easily drain through the filter cloth, thus enhancing the filtration effect. As the filter disc continuously rotates, a scraper pushes the thickened sludge from the disk. The filter cloth is backwashed with a spray bar.
