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