Rotary Drum Screen

The Rotary Drum Screen (Product ID: FTR) is designed to remove solids from industrial wastewater streams. It features a rotating screening drum installed within a tank. Wastewater enters through an inlet port and contacts the drum via a specially designed flow distributor, while filtered water exits through an outlet port.

Solids captured on the drum's external surface are removed by a fixed scraper, and an internal washing system keeps the screen element clean. An optional integrated Screw Compactor (SCC) is available to wash and dewater the captured screenings.

Advantages:

Low investment and maintenance costs
Compact design for limited installation space
Simple operation and maintenance
Self-cleaning drum ensures continuous performance

The Rotary Drum Screen has a capacity range from 3 to 1,700 m³/h. It is available in screen options including wedge-wire ranging from 0.25 to 2.50 mm and rounded holes ranging from 1.5 to 2.5 mm.
