In this article, the pervaporation selectivity as a function of the membrane thickness is studied for the dehydration of acetic acid. From this study, it appeared that the selectivity of polysulfone (PSF) , poly (vinyl chloride) (PVC ) , and polyacrylonitrile (PAN) decreases with decreasing membrane thickness, below a limiting value of about 15 pm. However, in the case of gas separation, the se...

one of the barriers during whey filtration using uf membrane is the fouling phenomenon of the membrane, which is caused by whey proteins. in this work, the uf membranes were prepared using polysufone (psf), dimethyl formamide (dmf), 1 wt.% poly vinyl pyrrolidone (pvp) and different concentrations of licl via phase inversion induced by immersion precipitation. the prepared membranes were charact...

This paper reports on the synthesis and characterisation of polysulfone (PSf) ultrafltration (UF) membranes modifed with carbon coated alumina Ni-doped titanium dioxide (CCA/Ni-TiO2) nanoparticles. The syntheses of the membranes was carried out using the phase inversion process. The ...

Fouling has become the main problem in long-term application of ultrafiltration (UF) membrane for water and wastewater treatment, significantly reducing productivity. In this paper, fouling on polysulfone-based was analyzed using Hermia’s model during textile treatment. The UF been prepared by blending polysulfone (PSf), acetone, PEG400 DMAc, with ZnO nanoparticles at a concentration 1% weight ...

Gas-separation membranes are a critical industrial component for low-carbon and energy-efficient future. As result, many researchers have been testing membrane materials over the past several decades. Unfortunately, almost all membrane-based systems home-built, there no widely accepted material standards or protocols in literature, making it challenging to accurately compare experimental result...

UV-induced grafting technique was used as a flexible method for surface modification of Polysulfone (PSf) ultrafiltration (UF) membranes in order to prepare hydrophilic nanofiltration (NF) membranes. Flat sheet Polysulfone (PSf) ultrafiltration membranes were prepared via phase inversion method. N-methylene-2-pyrrolidone (NMP) and polyethylene glycol (PEG) of three different molecular weights (...

This study investigated the effect of Cloisite15A (C15A) organoclay in the substrate layer on the performance of reverse osmosis (RO) membranes. The substrate of the RO membranes was modified using different loading of C15A (ranging from 0.3 - 0.7 wt%) within polysulfone (PSf) substrate and the polyamide (PA) selective layer was formed on the top. Effect of the modified substrate layer on the w...

One of the barriers during whey filtration using UF membrane is the fouling phenomenon of the membrane, which is caused by whey proteins. In this work, the UF membranes were prepared using polysufone (PSf), dimethyl formamide (DMF), 1 wt.% poly vinyl pyrrolidone (PVP) and different concentrations of LiCl via phase inversion induced by immersion precipitation. The prepared membranes were charact...
