Abstract

Wastewater treatment has become a pressing challenge due to the generation of its large amount by daily life usage and industrial processes. To this regard, membrane technology has been a household name for such treatment. In this work, three inorganic additives, namely silicon dioxide (SiO2 ), titanium oxide (TiO2 ) and zinc oxide (ZnO) were selected and blended with polyethersulfone (PES) to prepare a PES-composite membrane using the phase inversion technique. The effects of various inorganic additives on performance of as-membranes for oil water emulsion separation were evaluated via the cross-flow ultrafiltration process. Membranes embedded with TiO2 nanoparticles (NPs) presents the highest permeate flux and pure water flux of 7.95 kg/m2.h and 21.68 kg/m2.h, respectively. Furthermore, it also presents the lowest fouling phenomenon among the membranes with relative flux reduction and flux recovery ratio of 63.33% and 48.57%, respectively.
