Polyethylene/TiO 2 membranes were fabricated via thermally induced phase separation (TIPS) method. A set of characterization tests including FE‐SEM, EDX, XRD, DSC, TGA, DMA, mechanical test and relative pure water flux for carried out to investigate the effect TiO nanoparticles on membrane properties. The results XRD TGA analyses confirmed presence in polymer matrix. DSC analysis revealed that melting point as well crystallinity increased slightly with increasing content. However, glass...
ABSTRACT In this work, neat and modified nanodiamond (ND) particles were embedded into high‐density polyethylene (HDPE) membranes to improve hydrophilicity antifouling properties. The prepared via thermally induced phase separation (TIPS) method used for pharmaceutical wastewater treatment in membrane bioreactors (MBR) system. To prevent the agglomeration of ND, it was using two methods: thermal carboxylation (ND‐COOH) grafting with glycol (ND‐PEG). Membranes different concentration ND‐COOH...
Abstract Polyethylene glycol‐b‐poly(1,2‐dichloroethylene)/polyvinyl chloride membranes were prepared and evaluated in oily wastewater treatment. The fouling mechanisms investigated using Resistance‐in‐series Hermia's models. effects of membrane composition on the also studied. surface hydrophilicity, roughness, density finger‐like voids porosity enhanced by blending PEG‐b‐PDCE. pore size shifted toward smaller pores as PEG‐b‐PDCE concentration increased to 0.075 wt.%. M‐3 was found be best...
Abstract The aim of this work is to prepare polypropylene (PP) membrane by embedding carboxylated(‐COOH) and also polyethylene glycol(‐PEG) functionalized nanodiamond improve hydrophilicity decline fouling in pharmaceutical wastewater treatment. Porosity, contact angle, mechanical strength, field emission scanning electron microscopy (FESEM) pure water permeation analysis were performed for the characterization membranes. membranes with 0.75 wt.% nanoparticles introduced highest flux,...
ABSTRACT In this study, ZnO/polyethylene membranes were fabricated via thermally induced phase separation method. A set of tests including FE‐SEM, EDX, XRD, DSC, TGA, DMA, mechanical test, and pure water flux (PWF) for characterization carried out. The results TGA analyses confirmed the presence ZnO nanoparticles in polymer matrix. DSC analysis revealed that melting point as well crystallinity increased slightly with increasing content. However, glass transition temperature was not affected...
In this study, neat HDPE and HDPE/PE-g-MA/EVA blend membranes were fabricated via thermally induced phase separation (TIPS) method their fouling behaviors examined using filtration of BSA protein. Membranes characterized FESEM, AFM, ATR-FTIR analyses porosity measurement. Fouling behavior was analyzed the resistance-in-series (RIS), classic combined pore blocking models. The results RIS model revealed that magnitude inherent, reversible irreversible resistances decreased from 0.611 ×1013m-1...
Abstract Graphene oxide (GO) was modified by citric acid (CA) and embedded into polyvinyl chloride (PVC) membranes. The PVC/GO‐CA (0.15 wt %) membrane showed the best hydrophilicity, porosity, tensile strength. results of membranes' performance in a bioreactor (MBR) system demonstrated that critical flux had noticeable improvement after adding 0.15 % GO‐CA. Also, irreversible fouling ratio membranes lower than neat PVC membrane, indicating an antifouling properties nanocomposite membrane....
