PREPARATION METHOD OF HOLLOW FIBER MEMBRANE FOR WATER TREATMENT USING CELLULOSE-BASED RESIN

摘要

The present disclosure relates to a preparation method of a hollow fiber membrane for water treatment that involves preparing a spinning composition including a cellulose-based resin, a poor solvent, a plasticizer, and an organic solvent and then spinning the spinning composition on a nonsolvent to form a hollow fiber membrane. Accordingly, the present disclosure overcomes the drawbacks of the conventional preparation method for hollow fiber membranes and thus provides a nano-filter (NF), reverse osmosis (RO) hollow fiber membrane for water treatment that easily enhances the properties of the separation membrane for water treatment and secures high reproducibility and high efficiency at low costs.
