The specialists for environmental technology

The Screw screen is a fine screen with a high screenings capture rate and excellent protection for membrane systems, use in water and waste water treatment.

Functional principle:
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.

Features:
• High reliability through robust construction
• No additional cleaning systems
• Screenings conveyed positively to the discharge point
• Excellent cost/performance ratio
• Low maintenance costs
• Suitable for outdoor sites / operation in winter
• Easily adapted to suit changed operating conditions
• Machine completely hygienically encapsulated
