Synthesis of polyethersulfone (PES)/GO-SiO mixed matrix membranes for oily wastewater treatment.

The treatment of oily wastewater continues to pose a challenge in industries worldwide. Membranes have been investigated recently for their use in oily wastewater treatment due to their efficiency and relatively facile operational process. Graphene oxide (GO) and silica (SiO) nanoparticles have been found to improve membrane properties.
