The development of filtration technique for water purification has been performed ranging from the conventional to the advanced technique such as coagulation, sedimentation, sand filtration, reverse osmosis and nanofiltration. However, the major challenge to be addressed in the filtration technique is the tendency of membrane fouling or clogging. This effect causes a decreasein the flux and effectiveness of membrane filtration. In this study, we reported the fabrication of poly (acrylonitrile)/PAN nanofiber membrane by electrospinning technique and their application for water purification. A drum collector electrospinning system was used to produce uniform nanofiber membrane. Nanofiber membrane was fabricated from precursor solution which was prepared by dissolving poly (acrylonitrile) that has molecular weight of 150.000 g/mol in n,n-dimethylformamide (DMF). PAN nanofiber membrane were fabricated via electrospinning technique with 8wt% in concentration. The morphology of the membrane was characterized by using Scanning Electron Microscopy (SEM). SEM analysis showed that uniform nanofiber was formed with average fiber diameter of 290-370 nm. Three different concentrations of antacid suspension were prepared as the sample in order to test the performance of PAN nanofiber as membrane filter. Flux test was carried out by applying various pressure against the membrane in order to obtain the flux values of each variation of waste water model. The purity of the filtrate was analyzed by using UV spectrophotometer and the result show a decreased absorbance by 93%.
