Screw presses

A screw press provides sludge dewatering by passing the sludge along the inside of a permeable cylinder. It uses a slowly-rotating (~5 RPM) Archimedean screw within a cylindrical screen (otherwise termed drum filter/screen or basket). It is normally inclined by ~20° to the horizontal to assist with the draining of water into the sump, and the screen aperture rating is generally below 0.5 mm.
