The purpose of dewatering is to remove water from a material or structure so that it can be reused or disposed of in a safe manner. Without this process, many materials would be unusable or pose a safety hazard. Dewatering can be used for a variety of purposes, including: Lowering the water content of slurry prior to transport.
