FSM - Screw Screen

The waste water flows through a perforated basket. The installation angle is 35° or 90°. The basket is fixed and cleaned by a rotated screw with a cleaning brush. The screening is transported, washed and compacted by one screw. This design guaranteed that no screening can pass the screen by “carryover” effect.

The screw is designed in the dewatering zone  with shaft to reduce the wear and prevent a blockage. Perforation for the screen basket is from 2 mm up to 10 mm. The cleaning of the basket is performed by a brush. The drive is realized by a gear motor at the top.
