Improvement of PES MF membrane performance using silica mesoporous FSM-16 modified with metformin (FSM-16-Met)

The silica mesoporous FSM-16 modified with metformin (FSM-16-Met) is known as new additive formembrane modification. In the creation of microfiltration membrane, polyethersulfone (PES) was chosenas the main polymer. With benefiting from the FSM-16-Met additives, the modified membranes exhibitedexcellent anti-fouling affection, while a high pure water mass transfer efficiency without notable oilpermeation was observed. The optimal modified PES/FSM-16-Met membrane indicated enhancement inpure water flux (PWF) and water contact angle (WCA) compared to the bare membrane. The high fluxrecovery ratio (FRR) (97%), during the oily effluent separation, is one of the obtained features in thiswork.
