“…Whereas, in thin film nano-composite membrane nano- particles form thin film on membrane surface through self-assembly by dip-coating method or deposited on prepared membrane surface with pressure [57]. Pour jafar et al [58] prepared thin-film nano-composite membrane of Polyethersulfone (PES) with TiO 2 nano-particles using additives (PVA and glutaraldehyde) by dip-coating method. They also fabricated TiO 2 entrapped PES mixed matrix membrane by dissolving TiO 2 in DMAc alongwith PVP additive, prepared casting solution was stirred for 24h at 25°C.…”

“…As antibacterial agents, these materials find application in water treatment, purification and desalination [143][144][145][146]. Yasin et al [58] fabricated mesoprous carbon nano-composite polyethersulfone membranes and observed high antibacterial ability and protein rejection when these membranes have 0.20 wt % concentration of MCNs. Enhanced water flux, hyrophilicity and increased antibacterial activity of mesoprous carbon PES nano-composite membrane was also observed.…”

During last few decades, membrane technology has emerged as an efficient technique over conventional methods due to its high removal capacity, ease in operation and cost effectiveness for wastewater treatment and production of clean water. Membrane based separations are commonly based on polymeric membranes because of their higher flexibility, easily pore forming mechanism, low cost and smaller space for installation as compared to inorganic membranes. Commonly employed membrane fabrication phase inversion method has been shortly reviewed in this article. Major limitation of membrane based separations is fouling and polymeric membranes being hydrophobic in nature are more prone to fouling. Fouling is a deposition of various colloidal particles, macromolecules (polysaccharides, proteins), salts etc. on membrane surface and within pores thus impedes membrane performance, reduces flux and results in high cost. Modification of polymeric membranes due to its tailoring ability with nanomaterials such as metal based and carbon based results in polymeric nano-composite membranes with high antifouling characteristics. Nanomaterials impart high selectivity, permeability, hydrophilicity, thermal stability, mechanical strength, and antibacterial properties to polymeric membranes via blending, coating etc. modification methods. Characterization techniques has also discussed in later section for studying morphological properties and performance of polymer nano-composite membranes. Graphical Abstract

“…With the performance and characteristics pores lies between ultrafiltration and reverse osmosis, nanofiltration (NF) process have high retention flux, relatively low operating pressure and high rejection towards multivalent salts [1][2][3]. However one of the major drawbacks of TFC membrane is susceptibility towards fouling thus rendering their overall performances.…”

Abstract. Thin film nanocomposite (TFN) membrane with copperaluminium layered double hydroxides (LDH) incorporated into polyamide (PA) selective layer has been prepared for magnesium sulphate salt removal. 0, 0.05, 0.1, 0.15, 0.2 wt% of LDH were dispersed in the trimesoyl chloride (TMC) in n-hexane as organic solution and embedded into PA layer during interfacial polymerization with piperazine. The fabricated membranes were further characterized to evaluate its morphological structure and membrane surface hydrophilicity. The TFN membranes performance were evaluated with divalent salt magnesium sulphate (MgSO4) removal and compared with thin film composite (TFC). The morphological structures of TFN membranes were altered and the surface hydrophilicity were enhanced with addition of LDH. Incorporation of LDH has improved the permeate water flux by 82.5% compared to that of TFC membrane with satisfactory rejection of MgSO4. This study has experimentally validated the potential of LDH to improve the divalent salt separation performance for TFN membranes.

Abstract:In this work, poly(ethersulfone) (PES) ultrafiltration (UF) hollow fibers (HF) were modified by introducing TiO 2 nanoparticles (TiO 2 -NPs) in the polymeric dope, to endow them with photocatalytic properties. Different dope compositions and spinning conditions for producing "blank" PES UF fibers with suitable properties were investigated. PEO-PPO-PEO (Poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene glycol, Pluronic ® (Sigma-Aldrich, Milan, Italy) was finally selected as the additive and a suitable dope composition was identified. After the detection of an appropriate dope composition and the optimization of the spinning parameters, PES-TiO 2 HF was produced. The optimized composition was employed for preparing the mixed matrix HF loaded with TiO 2 NPs. The effect of different TiO 2 NP (0.3-1 wt %) concentrations and bore fluid compositions on the fiber morphology and properties were explored. The morphology of the produced fibers was analyzed by Scanning Electron Microscopy (SEM). Fibers were further characterized by measuring: pore size diameters and thickness, porosity, and pure water permeability (PWP). The photocatalytic activity of the new membranes was also tested by UV light irradiation. The model "foulant" methylene blue (MB) was used in order to prove the efficiency of the novel UF membrane for dye photo-degradation.
