Reverse Osmosis Properties of Ionic and Nonionic Polymer Membranes
The performance of a homogeneous polymer membrane in reverse osmosis may depend on various chemical and physical properties of the polymer and on the morphology of the membrane. Generalized criteria necessary for optimum reverse osmosis performance in terms of chemical structure of the macromolecule may not be evident. On the other hand, some physicochemical properties such as the equilibrium water content of the membrane may play a more important role than the chemical nature of the macromolecule. This seems to be particularly true for ionic polymeric membranes. Therefore, generalized criteria for an optimum reverse osmosis membrane may be sought from a study of the fundamental interaction between the polymeric membrane and water.
