Study on reverse osmosis membrane separation of binary organic liquid mixtures.

Abstract

There is an increasing interest for the separation of organic liquid mixtures with reverse osmosis primarily due to its great promise in industrial applications. Based on Surface Force-Pore Flow model (SFPF) developed by Matsuura and Sourirajan, the study was conducted with the aid of a computer program, for the separation of organic liquid mixtures by reverse osmosis for the purpose of design and prediction of membrane performance. The results show that for a given separation system the pore size on the membrane surface and the interaction force between the membrane material and solute are two important factors which govern the effectiveness of the membrane separation of organic liquid mixtures.
