Insights

Passavant® Screw Press Sludgless consists of a static circular drum with an internal screw conveyor. The drum is fabricated in stainless steel using a special wedge-wire screen profile with large surface to obtain optimum liquid drainage characteristics.

The liquid continuously drains through the drum wedge-wire screen and gravitates to the filtrate outlet where it can be discharged or returned for treatment.
