Dewatering / d iː ˈ w ɔː t ər ɪ ŋ / is the removal of water from solid material or soil by wet classification, centrifugation, filtration, or similar solid-liquid separation processes, such as removal of residual liquid from a filter cake by a filter press as part of various industrial processes.. Construction dewatering, unwatering, or water control are common terms used to describe ...
Sludge dewatering is, as the name clearly implies, removing water from sludge. Sludge dewatering is typically the final step for industrial wastewater treatment processes and plants. After wastewater treatment the sludge remaining is very high in water content that can be reclaimed through sludge dewatering.
Dec 20, 2017· The use of "dewatering units," as a regular part of the drilling fluid treatment process on drilling rigs, continues to increase. A dewatering unit, the final phase of a solids control program, is designed to discard no free liquid. A solids control program in which a dewatering unit is used is referred to as a … Continue reading "Dewatering Units And Equipment"

May 17, 2018· Moisture content is a critical criterion to determine the acceptability of treated sewage sludge (called biosolids or sludge cake) as an acceptable product for use as a fuel and a nutrient-rich organic material. Moisture analyzers play a vital role in quality control procedures at sludge dewatering …
Efficient water recovery. Frequent delivery of freshwater resources to the rigsite can drastically impact the profitability of your wells. Water clarification or dewatering is the chemical process by which water-based fluids, including brine systems and slurries, are treated to separate water from the suspended solids.
