The separation process starts inside the screen which holds back solids only. The internal part of the screen is continuously cleaned by special 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.
