Rotary Drum Screen FTR

The Rotary Drum Screen model FTR removes solids from industrial wastewater streams. The Rotary Drum Screen consists of a rotating filtering or screening drum that is fitted in a tank.
Wastewater entering the tank through the inlet port contacts the external surface of the rotating drum via a specially designed flow distributor. Screened water flows through the drum screen surface to the outlet port.

The captured solids or screenings are removed from the external surface of the drum by a fixed scraper. The screen element is kept clean by a washing system fitted inside the drum.
As an option, the Rotary Drum Screen can be supplied with an integrated Screw Compactor (SCC) to provide for washing and dewatering the captured screenings.
