Polyethersulfone (PES) was modified by blending it with polyaniline (PANI) nanoparticles to improve the membrane performance. Three types of membranes: PES (controlled sample), PES-PANI selfsynthesised, and PES-PANI (commercial), were evaluated by direct interaction with BSA, humic acid, silica nanoparticles, Escherichia coli and Bacillus bacteria. The surface hydrophilicity of the modified PES membranes was enhanced by the addition of PANI nanoparticles and showed improved fouling resistance and a high flux recovery ratio as well as improvement in BSA and humic acid rejection even with higher pore sizes. The modified membrane also showed less attack from the bacteria, demonstrating improved biofouling activity.

The shortage of clean water sources and increase of demand for fresh water have become as major globalchallenges not only in industries but also inhuman life. Meanwhile, membrane technology has beenextensively noticed due to high separation efficiency, energy-saving and environmentally-friendly characteristic. So, development of new membrane is a vital step in advancing of membrane application inwater-treatment. This paper presents a comprehensive review on development of high-performancenanofiltration membrane based on nanotechnology for wastewater treatment. Application of new nanomaterialshas enabled fabrication of NF-membranes with improved separation properties for pollutantsremoval from water. Recognizing that conventional membranes are not necessarily suitable for industrialapplications and/or process intensifications many attempts were made recently to use of nanomaterialsinto NF-membranes, aiming to overcome trade-off relationship between flux/selectivity and to improvetheir stability. So, development of new structured nanomaterial with desirable properties is one of mostcrucial research topics for membrane researchers. Accordingly, an overview on different methods todesign of advanced nanomaterial presented that allow us to overcome their inherent problems in membranesfabrication such as agglomeration, defects formation, insufficient pores’ tuning, poor active sitesand anti-fouling properties; however, selection of appropriate nanomaterials is a challenge of utmost difficulty. Various types of nanomaterials such as zeolites, carbon based, framework (MOF/ZIF/COF), nanobiopolymersand special nanoparticles such as SFNPs, SFNCs, POSS, ZCPs, and nickel hydroxide nanosheetare presented and their roles in NF-transport are discussed as well as strategies for surface modificationof nanoparticles to promoting their surface charges density. Moreover, fabrication methods of nanoenhanced NF-membranes including layer by layer assembly, hollow fiber spinning, electrospinning ofnanofibers, construction of thin-film nanocomposite besides blending, co-polymerization; cross-linkingand grafting techniques are discussed. A proper view for selection of appropriate nanoparticles in membranefabrication is offered while considering types of pollutants to be removed.
