Fabrication of polyethersulfone ultrafiltration membrane for reducing organic compounds in water

Abstract Research has been carried out on hydrophobic membranes based polyethersulfone (PES) polymers using Mg(OH) 2 additives. PES are made by blending additive because structurally bound OH groups play an important role. In addition, is also cheap and easy to obtain non-toxic. This study aims improve the performance of membranes, studying effect adding additives into membrane system which was evaluated analyzing changes in surface shape scanning electron microscope, chemical structure ATR-FTIR, porosity, mechanical properties. The being reviewed water permeability testing rejection organic compounds. results SEM photos showed that addition affects structure, where large macrovoids formed modified decreases tensile strength membrane. Additives increases porosity range 12–40%. leads increase performance, with a higher 56.4 L/m ·h·bar 65% rejection. These findings indicate ultrafiltration can be used reduce compounds water.
