oily wastewater treatment using modified microfiltration membrane

New polyethersulfone (pes) microfiltration (mf) membrane was fabricated via phase inversion method using a melaminemodified zirconiumbased metalorganic 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 oilwater 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.
