✦ Synopsis

This paper presents the results of research into concentrating xylose solution by using cellulose acetate reverse osmosis ( CA RO ) dry membranes which contain different additives. According to the feasibility test, CA-CTA,,, type mixed membranes and CA,,, membranes were found effective to concentrate aqueous xylose solutions. The membranes were fitted into plate type desalters, and the desalters replaced the original Three Boiling System in the xylitol production process. After 3f years, the rejection of the membranes was still good although the flux had slightly decreased; the used membranes could be used again after mechanical cleaning. This paper also discusses the factors which affect the service life of the membranes and suggests the methods to eliminate the effects.
