Silver nanoparticles (NP) was successfully immobilized on polydopamine (PDA) supported polyethersulfone (PES) membrane via a redox reaction. Polyvinylpyrrolidone (PVP) was added into membrane dope solution as a pore-forming agent. Four pieces of membranes (M1, M2, M3 and M4) were fabricated with different active layer coatings to compare their morphological and performance properties. The differences between each sample were highlighted as follow: M1 (pristine PES), M2 (PES+PVP), M3 (PDA/PES+PVP) and M4 (Ag/PDA/PES+PVP). All membranes were characterized using scanning electron microscopy, ener

Membrane based separation system is considered as a promising technology to purify water, owing to its simplicity and efficiency in operation. However, the application is limited by membrane fouling, which can lead to the declination of water flux and premature failure of membrane. The fouling can be controlled through membrane surface modification by blending hydrophilic materials during the casting solution preparation. Polyethersulfone (PES) membrane is naturally hydrophobic due to lack of oxygen functional group, which limits its application in the filtration of water. Therefore, modificat

Abstract This study aimed to enhance the performance of polyethersulfone (PES) membranes for water treatment by incorporating hydrophilic additives– magnesium hydroxide (Mg(OH)2) and polyvinylpyrrolidone (PVP). Mg(OH)2 was selected to enlarge pore size, while PVP served as a pore-forming agent to improve hydrophilicity and fouling resistance. Membranes were fabricated using the phase inversion method, with varying Mg(OH)2 concentrations to optimize performance. Structural and chemical properties were evaluated using SEM, FTIR, porosity, and contact angle analysis. This modified membrane achiev

Polyethersulfone (PES)/polyacrylonitrile (PAN) membranes have been paid attention among membrane research subjects. However, very few studies are included in the literature. In our study, asymmetric ultrafiltration (UF) membranes were prepared from blends of PES/PAN with phase inversion method using water as coagulation bath. Polyvinylpyrrolidone (PVP) with Mw of 10,000 Da was used as pore former agent. N,N-dimethylformamide was used as solvent. The effects of different percentage of PVP and PES/PAN composition on morphology and water filtration properties were investigated. Membrane performan

The effect of CuCl2 content on the water flux and rejection was studied and the antibacterial properties of PES hollow fiber UF membrane were also investigated. The water flux results indicated that the hydrophilic properties of PES UF membranes were improved after adding CuCl2. The rejection of PVA-50000 was expe

Polyurethanes (PUs) are currently considered to be biocompatible materials but limited by a low resistance to thrombus. We therefore design a heparin-like PU (HLPU) to modify polyethersulfone (PES) membranes approaching integrated antifouling and antithrombotic properties by bioinspiration of heparin structure. Poly(vinyl pyrrolidone)-HLPU (PVP-HLPU) was synthesized via reversible addition-fragmentation chain transfer polymerization of VP using PU as a macroinitiator and then sulfonated by concentrated H2SO4. FTIR and NMR results demonstrated the successful synthesis of PVP-HLPU. By incorporat

Streszczenie:

Polyethersulfone (PES) is a polymer popularly used to produce ultrafiltration (UF) membranes. PES is relatively hydrophobic; thus, hydrophilic ingredients are added to the membrane matrix to reduce the fouling intensity. Ingredients such as polyvinylpyrrolidone (PVP) reduce the resistance of PES to NaOH solutions. This study investigated the possibility of using PES membranes for the separation of alkaline cleaning solutions. For this purpose, self-made PES membranes and commercial ultrafiltration PES membranes (UE10—10 kDa and UE50—100 kDa) containing PVP additive were used. The membranes wer

Forward osmosis (FO) has become a technology with great potential for numerous applications, including water desalination. One of the critical factors in determining the FO performance is the selection of the appropriate membrane material that compatible with draw solution.

The hazardous and mutagenic properties of dye effluents discharged into water bodies have led to the development of membrane separation for water treatment. pH-sensitive membranes have been widely employed as they exhibit remarkable improvements in the permeability and separation performance of polyethersulfone (PES) membranes. In this study, the PES membranes incorporated with polyvinylpyrrolidone (PVP), pluronic F108, and polyitaconic acid (PIA) by phase inversion were fabricated and characterized.

L’ultrafiltration (UF) du lait écrémé pour la standardisation de la teneur en protéines pour la fabrication des fromages est un procédé membranaire très répandu à l’échelle industrielle. Cependant, le colmatage des membranes par des protéines du lait écrémé provoque une baisse de la productivité et constitue un verrou de ce procédé.Ainsi, l’étape de nettoyage/désinfection bi-quotidienne est indispensable afin de restaurer les performances de la membrane et d’assurer la sécurité sanitaire ainsi que la qualité des produits.

Ces travaux portent sur l'étude du vieillissement de membranes d'ultrafiltration en PES / PVP. Ils sont motivés par le constat industriel de l'endommagement des membranes au cours de leur utilisation. Il est démontré que l'hypochlorite de sodium utilisé lors des procédures de lavages sur site de production d'eau potable est le principal responsable du vieillissement des membranes. Cette dégradation chimique conduit à une oxydation radicalaire de la PVP (avec et sans rupture de chaînes), entraînant son élimination partielle de la structure de la membrane.
