In this study, polyethersulfone (PES) hollow fiber membranes (HFM) were fabricated with different weight percentage (wt. %) of polymer at 16 wt. %, 18 % and 20 in order to study the impact percentages on membrane properties its dye rejection performance. Microfiltration HFM by using laboratory dry-wet spinning method. improve pore structure membrane, 3 (PVP) 8000 M.W. was added dope solution. A...
