Rapid filtration measurement of dewatering design and ...

To characterize and optimize the compressive dewatering of suspensions, rapidly determinable material parameters are required. A mathematical framework exists for characterization of dewatering using three parameters: the compressive yield stress P y (ϕ), the hindered settling function r(ϕ), and a solids diffusivity D(ϕ). A new variation on traditional constant pressure, batch filtration ...
