MANUFACTURING METHOD OF HALLOW FIBER MEMBRANE COMPLEX AND HALLOW FIBER MEMBRANE COMPLEX FOR WATER TREATMENT THEREBY

摘要

PURPOSE: A method for manufacturing a hollow fiber composite membrane and a water treatment hollow fiber composite membrane manufactured by the method are provided to maintain the membrane property and color of a hollow fiber composite membrane although the membrane is exposed to various kinds of water treatment chemicals. CONSTITUTION: A method for manufacturing a hollow fiber composite membrane comprises the steps of: coating a coating solution based on a composition containing a fluorine resin on the surface of a hollow fiber membrane made of one selected among poly (vinylidene fluoride), polyethylene, polypropylene, and poly (ether sulfone); and drying the hollow fiber membrane coated with the coating solution.
