Removal of Organic Dye in Wastewater Using Polyethersulfone Hollow Fiber Membrane

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. All PES characterized Scanning Electron Microscopy (SEM), Atomic Force Microscope (AFM), Fourier Transform Infrared Spectroscopy (FTIR) contact angle. The HFM’s performance evaluated terms rejection, Direct Red 80 as substitute organic wastewater. results ed that higher (20 PES) had thicker separation layer, smoother surface uniform like structures. (20% (67.33%) permeate flux (10.024 L/m2h) compared %. revealed did affect
