Abstract

Filtration membrane technology is a widely developed water treatment technique since it is easy to use, effective, and no addition of chemicals. Superior composite membrane performance lies in the selection of materials, synthesis techniques, and morphology. The article aims to examine the synthesis techniques and characteristics of polyethersulfone (PES)/Polyvinyl Alcohol (PVA)/metal oxide composite-based filtration membranes. In particular, the role of metal oxides filler (TiO2, ZnO, Fe3O4) toward membrane structure and properties is discussed in detail. Literature searches were conducted through ScienceDirect and Google Scholar. Identification and selection of articles were carried out through JabReff software based on the Scopus index in Q1 and Q2 in the last 5 years. The role of metal oxide filler toward membrane structure and properties was discussed systematically. It was found that there are 3 synthesis methods of PES/PVA/metal oxides membrane that commonly used i.e. (1) coating (2) dry jet/wet spinning and (3) electrospinning. Among those methods, the coating is the most considerable technique due to its capability on producing thin and dense membranes as well as modifying the surface properties of the membrane without affecting its intrinsic structure. The addition of PVA and metal oxides on PES membrane produced a composite membrane with improved hydrophilic nature (contact angle decreased from 26.76o to 65o) and porosity (28.2% to 70%). On the other hand, it reduced pore size from 29.6 nm to 4.7 nm. PES/PVA/metal oxide also demonstrated applications in term of dyes and salt rejection. Among the metal oxides, TiO2 was the best filler on PES/PVA membrane, as indicated by its morphological structure.
