Pore Blocking as the Fouling Mechanism in Carrot Juice Clarification by Microfiltration

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. Themechanism 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
