Chronic problems of water treatment membranes are fouling phenomena and membrane damage during the cleaning process. In this study, to solve these problems, a separation membrane in the form of a hollow fiber having excellent physical properties was produced by using the thermally induced phase separation (TIPS). The material used to make the water treatment membrane is poly(vinylidene fluoride) (PVDF). In the evaluation of the properties of the manufactured hollow fiber, citric acid which is an acidic solution and NaCl which is a basic solution were used and experiments of chemical resistance were proceed. In order to confirm the performance of hollow fiber membrane, water flux and tensile strength were measured. |
