Abstract The increasing occurrence of steroidal hormone micropollutant in the aquatic environment and their associated consequences have caused serious environmental concerns globally. Adsorptive removal hormonal pollutants using polymeric membranes has been suggested but information on performance various conditions is lacking. In this study, we examined effect salinity polyethersulfone (PES) ...

Biofouling is one of the most serious problems in membrane filtration systems for water treatment. An easily applicable antimicrobial finish polyethersulfone (PES) filter membranes shown by derivatizing an approved chlorin photosensitizer drug with adhesive ortho-catechol functionalities as known from l-3,4-dihydroxyphenylalanin (Dopa) residues marine mussel glues. The chemical structure second...

The fouling behaviour of microcrystalline cellulose (MCC) particles on polyethersulfone (PES) membranes was investigated using fluid dynamic gauging (FDG) and molecular dynamics (MD) simulations. Experimental cross-flow microfiltration (MF) a dilute MCC suspension at 400 mbar transmembrane pressure 0.45 μm PES revealed an estimated layer thickness 616 ± 5 for both fouled re-fouled applied shear...

BACKGROUND Little information is available regarding which type of dialyzer membrane results in good prognosis in patients on chronic hemodialysis. Therefore, we conducted a cohort study from a nationwide registry of hemodialysis patients in Japan to establish the association between different dialyzer membranes and mortality rates. METHODS We followed 142,412 patients on maintenance hemodial...

The goal of the current study is to enhance hemocompatibility polyethersulfone (PES) membranes using heparin immobilization. Heparin was immobilized covalently and via electrostatic interaction with positively charged PES surface (pseudo-zwitterionic (pZW) complex) investigate influence each method on membrane hemocompatibility. In situ synchrotron radiation micro-computed tomography (SR-µCT) i...

Poly(vinyl alcohol) (PVA)/polyethersulfone (PES) composite membranes were fabricated using two PVA polymers with molecular weights of 50,000 and 15,000 different crosslinker agents. The membrane the top layer consisting formaldehyde as found to have a better separation factor than others for pervaporative dehydration isopropanol. While adding 1.0 wt% graphene oxide could represent pervaporation...

In this study, the efficacy of electron beam irradiation versus chemical coupling for yielding polyethersulfone (PES) membranes with antibacterial properties was investigated. For the surface coating, a recently discovered lead compound, IL-KKA, comprising a short peptide sequence functionalized with imidazolium groups, was used. For better integration within the membrane, several novel variant...

Internal concentration polarization (ICP) is a major issue in forward osmosis (FO) as it can significantly reduce the water flux in FO operations. It is known that a hydrophilic substrate and a smaller membrane structure parameter (S) are effective against ICP. This paper reports the development of a thin film composite (TFC) FO membrane with a hydrophilic mineral (CaCO3)-coated polyethersulfon...
