This quarry was looking for a solution to delete the road pollution in the community. After a testing period the DK-Bridge 580 wide GWC 60 water clarifier was considered ideal for their application. Because of the constant flow of clean water blocked nozzles do not occur and the quality of the washing process is guarenteed over time. The collected mud is taken out of a steel tank and the clarified water is stocked in two large 20 m³ concrete tanks. Not only is this option the best in washing result but also civil works cost was reduced to an absolute minimum.
