Grit classifying:

Sediments from the grit trap are introduced in the upper part of the plant as a mixture of grit, organics and water. Due to the low surface overflow rate virtually all particles are separated and accumulate in the bottom part of the tank.

Grit Washing:

Due to the introduction of service water in combination with a slowly rotating circulation system the lighter organic particles can easily be separated from the dense mineral particles in the bottom part of the tank. After removal of the organic material the clean grit is automatically removed by a screw conveyor, at the same time statically dewatered, and discharged into a container.

The removed organics are continuously discharged with the introduced wash water.
