new polyethersulfone (PES) microfiltration (MF) membrane was fabricated via phase inversion method using a melamine-modified zirconium-based metal-organic framework (MOF). The wettability and permeability of the membrane were measured using water contact angle and pure water flux (PWF), respectively. By introducing the MOF additive (0.1 wt. %) to the membrane matrix, the performance of the membrane in the separation of the oil-water mixture (different oil concentrations of 300 and 500 mg/L) was enhanced. The flux recovery ratio (FRR) of the modified membrane was significantly increased to 90.76 % compared to that in the bare membrane (20.41 %). Furthermore, the antifouling property was considerably improved.
