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 flocculated sludge enters the inlet chamber into the drum zone where it is conveyed by spiral movement and is gradually compacted. 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. Spry nozzles together with the cleaning system wash the drum screen section. Eventually the solids will pass into the discharge section and to the outlet where they can be collected into a container or conveyed for eventual disposal.
 All main parts of the Passavant® Screw Press Sludgless are bolted to grant an easy and fast maintenance. Washing system with nozzles and internal cleaning device to wash the internal drum screen section.
