Technical Specs


WASTEMASTER GCPC is a Screw Screen that consists of a screen basket, a conveyor screw, and a compacting section. WASTEMASTER GCEC is almost identical with GCPC but misses the compacting section. It is suitable for applications in which screenings may not or cannot be compacted. Both machines are installed in a self-supporting container.
GCPC / GCEC are commonly used in above ground applications, both civil and industrial. Waste water is commonly pumped through the machine. Civil works are not required.
In-Pipe Screw Screens


The separation process starts inside the screen which holds back solids only. The internal part of the screen is continuously cleaned by brushes fixed on the outside diameter of the spiral. As the water runs through the screen the shaftless spiral conveys the solids up towards the
compacting module where the material is further de-watered. Depending on the material properties, screenings can be reduced by more than 35% of their original volume.
