Modeling of Gel Controlling Membrane Filtration in Fruit Juice Processing

Abstract

In this chapter, mathematical models aimed at describing the physical mass transport phenomena in the clarification of fruit juices with hollow fiber membranes in both laminar and turbulent flow regimes are presented. The mathematical analysis was based on the first principles using the integral method of solution to compute the developing concentration boundary layer over the gel layer. The analysis was extended for batch mode of filtration, and the profiles of permeate flux were computed for different operating conditions in the predictive mode. The simulated results were also compared with the experimental data of fruit juice processing with hollow fiber membranes.
