The flux behavior of polyvinylidene fluoride membrane (Durapore, HVLP) was examined during
cross-flow microfiltration (MF) of carrot juice and the observed flux decay was modeled using a
modified form of the differential equation used to describe classical dead-end filtration process. The
mechanism of fouling during the cross-flow microfiltration was identified by estimation of the
parameters model according to a nonlinear regression optimization procedure. Analysis of the
results revealed that this membrane separation process is controlled by a complete pore blocking
mechanism.
