Straight Screw screen as the ideal solution for pre-treatment of municipal and industrial wastewater

This is a separation unit used to capture and dewater screenings contained in wastewater. The screen is designed to reliably fulfill its function while being undemanding in terms of operation, maintenance, and space.

Straight Screw screen are suitable wherever truly fine pre-treatment using a perforated screen is required.

How does the Straight Screw screen work?

Water containing solid particles flows into the inner space of the screen, where it passes through the stainless steel filter screen, which separates screenings larger than the openings in the screen. The screen gradually becomes clogged with screenings, causing the level to rise. Once the set level is reached, the probe switches and the device starts automatically. The captured screenings are lifted by the rotating motion of the screw into the discharge chute, from where they fall, for example, into a prepared bin or container. In the area of the filter screen, the lifting screw is fitted with a wiping brush for efficient cleaning of the screen. Water free of floating impurities larger than the opening size flows to a possible next treatment stage.
