Abstract :
A new polyethersulfone (PES) microfiltration (MF) membrane, modified by applying metal-organic framework (MOF) was designed and prepared based on phase inversion method. The membranes hydrophilicity was evaluated by using water contact angle (WCA), the membranes permeability was examined by pure water flux (PWF) and also, the flux recovery ratio (FRR) calculated. Modified membranes showed acceptable enhancement after introducing additive to the membrane matrix (the 0.1 % wt. was chosen as optimal modified membrane). Also, the prepared membranes were tested during the oily wastewater filtration (different oil concentration, 300 and 500 ppm). Furthermore, the membrane antifouling properties were significantly improved.
