ProTechtor® Grit Washers

The Kusters Water grit washer was developed with two aims in mind:

  1. To achieve a very high separation performance of the finest grit particles.
  2. To achieve grit with < 3% total volatile solids.

The Kusters Water grit washer consists of two basic items – a rotating perforated screening drum and a grit separator/washer unit, however, if the plant has fine screens (<10mm perforated screens), the screening drum can be eliminated. Special emphasis has been placed on maintaining low water consumption while achieving high grit capture rates and low volatile solids concentrations. The Kusters Water grit washer accomplishes these while providing high performance coupled with low operating costs.

Funtional Principle
The grit/water mixture is fed in via the rotating screening drum (if required). Course screenings are held back in the screening drum and discharged to a dumpster, compactor, or conveyor. The mixture of grit and water is then delivered to the grit separator unit. Organic matter is held in suspension and floated off while the grit settles in the washer tank. With the addition of water, the settled grit is separated from the remaining organic constituents using a stirring device and up-current wash water technique. The washed grit is then removed from the container, de-watered and discharged via a shafted screw.
