2.1 INTRODUCTION
Membrane separation is an area deserving special attention because of its great potential for low capital cost and energy efficiency. To date, however, few membrane processes other than reverse osmosis and hydrogen separation have demonstrated any industrial utility primarily because of problems of speed and selectivity in separation [1].
