Cake filtration has been widely used in many chemical processes with more non-Newtonian, highly vis- cous and compressible materials involved. Neither traditional nor modern filtration theory can be applied in practice. "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 properties of solid/liquid system and operation parameters; and (2) to calculate cake specific resistance and its variations with time at various cake thickness locations.
