The TR-TRD screens are used for solid-liquid separation for high flow rates. They combine screenings removal and compaction in a single device. 

The TR-TRD features a screen basket with a perforated or wedge wire barrel that filters out screenings as it rotates with an internal conveyor screw. Screenings are conveyed up the screw where they end at a compacting and dewatering modulus. The screenings opening can be fitted with a discharge chute or a bagging system. 

The system can be both channel and tank mounted.
