Weighted Calculation For Membrane Permeability Of Nanofiltration And Reverse Osmosis

Authors : Mehdi Metaiche .


The objective of this work is to present a method for determining water and salt permeability of nanofiltration (NF) and reverse osmosis (RO) membranes. This method is based on the Van der Meer algorithm for calculating transfers across NF and RO membranes for different types and geometries of modules. The algorithm was developed for a weighted calculation of permeability. The weighting elements are: elementary membrane surface, transmembrane pressure, pressure drop and concentration gradient. The results obtained through the exploitation of the experimental data are satisfactory.
