In the production and use of sand and gravel, it may be necessary to dewater the products for various reasons such as:
- Meet the environmental regulations and standards on liquid rejects (reduced load to environment and safe water because of closed water cycle)
- Stricter requirements on sand quality and residual moisture for concrete production (hydraulic engineering or road construction)
- Removal of impurities to get so-called "clean" aggregates
- Reuse wash water to limit the consumption of water
- Limit solid volume for evacuation
