In this study Fe3 O4-polyethersulfone (PES) membranes were prepared in the present of a magnetic field or without a magnetic field by using the phase inversion process. A comparison of membrane properties was investigated. Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDX) were used to determine the morphology and chemical composition of the prepared membranes. Furthermore, the fouling analysis of the non-magnetized and magnetized Fe3 O4-PES membranes were also conducted through the filtration study. The pure water flux of membranes increased from 158.49±11.96 L/m2·hr (neat PES) to 187.06±6.54 L/m2·hr (magnetized Fe3 O4-PES). These results showed that the magnetized Fe3 O4-PES membrane not only had the high pure water flux but also had a high HA rejection and good antifouling ability. As such, magnetized Fe3 O4-PES membrane had excellent comprehensive properties which could use for water remediation. © 2022 Trans Tech Publications Ltd, Switzerland.
