Description

GCP is a Screw Screen that consists of a screen basket, a conveyor screw, and a compaction section. GE is almost identical with GCP but misses the compaction section. It is suitable for applications where screenings may not or cannot be compacted.

Function

The process starts in the screen that holds back solids only. The internal part of the screen is continuously cleaned by brushes fixed on the outside diameter of the flighting. As the water runs through the screen the shaftless spiral conveys the solids up towards the compaction module where the material is further de-watered. Depending to the material properties, screenings can be reduced by more than 50% of their original volume.

GCP = screw screen press for channel installation
GCP/C = screw screen press installed in a self-supporting container
GE = screw screen without compaction for channel installation
GE/C = screw screen without compaction installed in a self-supporting container

GE model, without compacting zone, has been developed mainly to be used in industries where solids do not require any forced de-watering (e.g. plastics) or may not be de-watered.
