Outline of Final Research Achievements

Biopolymers, defined as hydrophilic organic macromolecules in natural water, have been identified as major players in membrane fouling. In this study, glycoblotting, which was developed to specifically capture oligosaccharides in the field of medical science, was applied for establishing a new pre-pretreatment for membrane processes in water treatment. Removal of biopolymers was limited under a normal temperature. However, use of catalysts such as aniline or oxidants enabled to remove biopolymers via glycoblotting under a normal temperature. It was suggested that biopolymers detected by the conventional method should be further fractionated to investigate membrane fouling caused by biopolymers. Modified liquid chromatography with organic carbon detection (LC-OCD) analysis enabled the further fractionation of biopolymers.
