• A hybrid process coupling nanofiltration and ozonation was assessed. pre-ozonated solution mixed to the water treat doped with H 2 O . Two pharmaceuticals were efficiently removed in both retentate permeate. Membrane fouling decreased by a factor two using river sample. Organic membranes not degraded oxidants water. This study assesses feasibility of designing / membrane that can simultaneous...

Application of nanoparticles as additives in membrane synthesis for improving the resistance of membranes against fouling has triggered recent interest in new membrane types. However, most nanoparticle-enhanced membranes suffer from the tradeoff between permeability and selectivity. In this study, nano-WS2 was explored as the additive in membrane synthesis by non-solvent induced phase separatio...

Enzymatic modification of polyethersulfone (PES) membranes has been found not only feasible, but also an environmentally attractive way to vary surface properties systematically. In this paper, we summarize the effect of modification layers on protein adsorption and bacterial adhesion on PES membranes and surfaces. The enzyme laccase was used to covalently bind (poly)phenolic acids to the membr...

a microporous bisphenol a diglycidyl ether (dgeba) epoxified-polyethersulfone (pes) blend membrane (epes membrane) was prepared through dry-wet phase inversion. this study attempts to correlate the changes in membrane physical and chemical properties when the epes membranes were exposed to different durations of dry-phase inversion, towards the separation efficiency of carcinogen chromium (vi)....

One major challenge in utilization of ultrafiltration (UF) membrane for wastewater treatment is its inevitable tendency biofouling (from biomolecules to microorganisms). To overcome this challenge, nanostructured cellulose membranes with hydrophilic surface and high porosity (∼80% without pressurization) was demonstrated study. The consisted a lyocell microfiber scaffold infused nanofibers (CNF...

Membrane-based technologies have been widely used for surface water treatment. Yet, many aspects of this technology can still be improved. This study aims to develop polyethersulfone (PES)-based phase-inverted membranes improve the morphological structure, antimicrobial properties, and performance by incorporating Poloxamer 188 patchouli oil as dope solution additives. The membrane was assessed...

In this work we presented a general strategy for the fabrication of membranes with well-defined ions transport channels through solvent-responsive layer-by-layer assembly (SR-LBL). Multilayered poly (diallyldimethylammonium chloride) (PDDA) and poly (acrylic acid) (PAA) complexes were first introduced on the inner pore wall and the surface of sulfonated poly (ether ether ketone)/poly (ether sul...

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...
