Modeling of Hollow-Fiber Membrane System During Ultrafiltrat

ABSTRACT:
The present study aims to evaluate the performance of hollow fiber
membrane module during ultrafiltration of aqueous solutions. The model
is represented by a set of differential equations for permeate and residue
pressure drop and volumetric flow rates in the axial direction, beside the
principle equations of both solvent and solute fluxes through the
membrane, while osmotic pressure was neglected in model equations.
The shell and tube module type was considered where feed pass in the
shell and permeate in the bore side. Tortousily factor of membrane pores
in addition to concentration polarization modulus were taken into account
in calculations. The model was solved numerically with the help of
suitable program in both cocurrent and countercurrent flow pattern and
comparison of results were carried out.
