Microfiltration is described by a mathematical model taking into account complete pore blocking, gradual pore blocking with an increase in the retentivity of the microfilter (standard blocking), primary layer (sublayer) formation, and cake formation. Membrane porosity is described by a lognormal pore-size distribution. The convexity of the kinetic curve (time divided by filtrate volume versus time) is examined for each of the elementary processes. Microfiltration kinetics are analyzed, and an approach to the design of microfilters is suggested. Theoretical estimates are compared with experimental data.
