Abstract

A process for modifying a separation membrane, characterized by making water which contains a polyphenol-containing organic substance permeate a separation membrane under pressure to impart bactericide resistance to the membrane and then feeding bactericide-containing water to the membrane to sterilize the membrane, by making water which contains both a polyphenol -containing organic substance and silver ions permeate a separation membrane under pressure to immobilize the silver ions on the membrane through the organic substance and thereby enhance the antibacterial performance of the membrane, or by making water which contains both a polyphenol-containing organic substance and a reducing agent permeate a separation membrane under pressure to enhance or recover the rejection performance of the membrane; an apparatus for the process; and separation membranes modified by the process. The modified separation membranes of the invention are effectively improved in bactericidal or antibacterial performance or in rejection performance.
