In this study is presented the result obtained for treatment of waste water from medical sector using membrane filtration system. Polyethersulfone (PES) membranes were Dimethylformamide DMF like solvent, with different concentration to determine rejection variation dyes. Membranes by immersion precipitation method and permeation properties determined dead end technique. The results show that ca...

A novel polyethersulfone (PES) mixed matrix membranes (MMMs) loaded with iron (Fe) pillared nanoclay was fabricated for efficient rejection of bisphenol (BPA) from water. Low–cost one dimensional (1D) halloysite (FePHNTs), two (2D) bentonite (FePB), and 2D Cloisite 15A (FePC15A) were synthesized via pillaring procedure. XRD, TEM, EDS BET results indicated that the nanoclays successfully pillare...

Demineralized and disinfected waters may have very low microbial loads, requiring that large volumes of water are filtered to recover enough biomass for further analysis. Extended filtration periods, often interrupted by clogging, a major limiting factor concentrate samples’ microbiota examination, besides hindering the work pace. In this study, we investigated performance three types filtering...

In this work membrane (proton exchange membrane) by using the blend polymers (polyethersulfone (PES), Expandable polystyrene (EPS), polyvenylidinefluride polymer (PVDF)) were prepared. This was modified adding organic sulfonic acid to solution precasting process, and sulfonated dipping it in diluted sulfuric (H2SO460%) post casting process. The sulfonation confirmed via FTIR spectra. characteri...

Silver-impregnated membrane was facilely prepared by ex situ silver nanoparticles (NPs) blending method using polyethersulfone (PES) as the base polymer. A total of three membranes [F1(S0), F2(S0.5) and F3(S2.0)] were fabricated at different weight percentages of polymer and silver (Ag) loadings to compare their effects on membrane morphological and performance properties. All membrane types we...

This work studied the mix mode-I/II fracture behaviour of an aerospace-grade carbon fibre/epoxy composite that was interlayer-toughened by Polyamide-12 (PA), Polyphenylene-sulphide (PPS), Polyimide (PI), Polyethersulfone (PES) and Polyethylenimine (PEI) fibres. During laminate curing process, PA fibres melted, PPS PI kept in their original form PES PEI dissolved epoxy matrix. resulted different...

Polyethersulfone has been widely used as a promising material in medical applications and waste-treatment membranes since it provides excellent mechanical and thermal properties. Hydrophobicity of polyethersulfone is considered one main disadvantage of using this material because hydrophobic surface causes biofouling effects to the membrane which is always thought to be a serious limitation to ...

A well-designed scaffold that allows the full exposure of nanophotocatalyst to reactants is equally important with an efficient catalyst material in realizing a high-performance photocatalytic reaction. In this work, we develop three-dimensional (3D) bandgap tunable perovskite quantum dots (PQDs)/polyethersulfone (PES) monolithic film maximize specific area and enhance light harvesting, thereby...
