Cake filtration has been widely used in many chemical processes with more non-Newtonian,highly viscous and compressible materials involved.Neither traditional nor modern filtration theory can be applied in prac- tice."Equivalent cake filtration model"is a recently developed mathematical model to describe cake filtration for both Newtonian and non-Newtonian fluids,in either steady or unsteady filtration stages.This model has two strengths:(1)It can be used to determine equivalent capillary radii and predict filtration quality based on the prop- erties of solid/liquid system and operation parameters;and(2)to calculate cake specific resistance and its variations with time at various cake thickness locations.
