Tap water filtration system.
In the context of filtration, the moisture content remaining in filter cakes produced by dewatering devices—such as gravity, centrifugal, vacuum, or pressure filters—typically ranges from 8 to 15 percent.1
The efficiency of this process depends on several factors, including the properties of the suspension, such as its concentration and particle size distribution, the characteristics of the filtering material, and the specific forces applied to the suspension. If a material is particularly slimy, gelatinous, or compressible, specialized techniques like the addition of filter aids may be necessary to maintain effective separation.12
