Aggregate


Aggregate, gravel and sand dredged or excavated from quarries and open mines often go through multiple processes, particularly washing and dewatering, that benefit from the use of coagulant and flocculant chemistries.

Many applications for sand and construction aggregate require these materials be free of fines or impurities, so they are rinsed or “washed” with water to remove silt and clay particles, which become suspended in the wash water. Dober’s Water Treatment portfolio of natural chemistry solutions is engineered to accelerate the settling of fine particles, clarifying the water for reuse and greatly reducing the need for new makeup water, leaving vital resources available for other purposes.
