Abstract

PURPOSE:To manufacture a flat reverse osmotic membrane which has incorporated cloth and has applied layers of different thickness on both side of the cloth, by making the cloth, which is impregnated with a soln. of high molecular cpd. having reverse osmotic membrane forming ability, pass through a gap between curved applying surfaces together with a film put on its one side in layers.
