  • Separation Using Semi-Permeable Membranes (AREA)

Abstract

PURPOSE: To prevent contaminant from depositing and adhering on the surface of a permeable membrane in the separation and concentration of the solution to be treated under pressure by use of a permeable membrane by making the solution pass through the membrane after coating of water-sensitive high molecular material (for example, PVA) has been made on the surface of the permeable membrane.
