Resumen
Ultrafiltration membranes have been widely used in industrial technology due to their high removal effectiveness. Long-term use of membranes will reduce membrane performance, so cleaning is required to maintain stable membrane performance. Chemical cleaning has proven to be effective for removing impurities but can also have a negative impact on membrane life. Polyethersulfone (PES) is proven to have strong mechanical properties due to its hydrophobic nature, but this hydrophobic nature makes PES membrane performance less than optimal so a hydrophilic pluronic co-polymer is needed.

Resumen
Ultrafiltration membrane has been widely used for oily wastewater treatment application attributed to its cost-efficiency, ease of operation, and high separation performance. To achieve high membrane flux, the pores of the membrane need to be wetted, which can be attained by using hydrophilic membrane. Nevertheless, conventional hydrophilic membrane suffered from inhomogeneous dispersion of nanofillers, causing a bottleneck in the membrane flux performance. This called for the need to enhance the dispersion of nanofillers within the polymeric matrix. In this work, in-house-fabricated hydrous m

Membrane-based processes are a promising technology in water and wastewater treatments, to supply clean and secure water. However, during membrane filtration, biofouling phenomena severely hamper the performance, leading to permanent detrimental impacts. Moreover, regular chemical cleaning is ineffective in the long-run for overcoming biofouling, because it weakens the membrane structure.

Resumen
We investigated inorganic-organic membranes consisting of sulfonated-poly(ether sulfone) (S-PES) and ZrO2·nH2O with the aim of improving proton conductivity and blocking methanol. We prepared excellent uniform membranes by the method using ZrOCl28H2O as a precursor. The proton conductivity of the ZrO2·nH2O/S-PES (EW=850) composite membrane with 50wt% ZrO2·nH2O content was about four times higher than that of S-PES (EW=850). On the other hand, the methanol permeability of the ZrO2·nH2O/S-PES (EW=850) composite membrane with 50wt% ZrO2·nH2O content was almost the same as that of S-PES (EW=850).

Resumen
Acute and chronic inflammation are common in patients with end-stage kidney disease (ESKD). So, the adsorption of pro-inflammatory cytokines by the hollow fiber of the dialysis membrane has been expected to modify the inflammatory dysregulation in ESKD patients. However, it remains to be determined in detail what molecules of fiber materials can preferably adsorb proteins from the circulating circuit. We aimed this study to analyze directly the adsorbed proteins in the polymethyl methacrylate (PMMA) and polyethersulfone (PES) membranes in patients on predilution online hemodiafiltration (OL-HD

Abstract We present a new method for impregnation of silver nanoparticles (Ag NPs) at high loading on polyethersulfone (PES) membrane's external surface, simultaneously retaining native membrane's porosity – to achieve a high water permeate flux without biofouling. This was possible by PES membrane's surface modification with acrylic acid (AA), finally leading to AA-Ag-PES membrane. AA-Ag-PES had a high (9.04%) Ag-NP loading selectively on membrane surface, as discrete, smaller (mean size: 20 nm) nanoparticles (NPs). In nonfunctionalized Ag-PES, aggregated (mean size: 70 nm) NPs, with lower Ag

Membrane application is widespread in water filtration to remove natural organic matter (NOM), especially humic acid.
