In this study, the first part summarized several studies conducted in the literature to study flow and productivity in membranes and to enhance membrane performance.
The second part of this investigation focused on developing a mathematical model to analyze flow through the hollow fiber membrane using porous media model for various controlling
mbranes are self-supporting. Two types of module arrangement can be distinguished: (i) where the feed passes through the bore of the hollow fiber (lumen) whereas the permeate is collected on the outside
Hollow fiber membranes have the ideal fiber geometry that allows the construction of modules with a high surface area inside a relatively small module, thus creating high capacity membrane units.
