Fabrication of Nanofiltration Membrane from Polysulfone Ultrafiltration Membrane Via Photo olymerization
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 (...
متن کاملFouling and Rejection Characteristic of Humic Substances in Polysulfone Ultrafiltration Membrane
In this study, the ultrafiltration membrane for humic substance removal was prepared by blending polysulfone with a high concentration of PEG400 as additives. The influences of the additive to the fouling resistance capability and humic substances rejection of the polysulfone membrane were investigated. The addition of 35%wt of PEG400 concentration improved the pure water flux up to 200, but re...
متن کاملPolysulfone/Iron Oxide Nanoparticles Ultrafltration Membrane for Adsorptive Removal of Phosphate from Aqueous Solution
Excessive nutrient contents in water bodies renders eutrophication and causes undesired structural changes to the environment. One of the most straightforward strategies to address eutrophication issue is through the removal of nutrients such as phosphate ions from the water sources. A combination of membrane fltration and adsorption process is an attractive alternative...

متن کاملPhotocatalysts in Polysulfone Membrane for the Removal of Humic Acid: The Effects of PVP and PVA on Membrane Morphology, Separation Performance and Catalytic Hindrance
Photocatalytic membranes exhibit great potential for water treatment since they combine the filtration and photo degradation in a single unit. Although blending photocatalytic nanoparticles into polymeric thin film remains the simplest method to prepare the photocatalytic membrane, the entrapped photocatalyst showed less catalytic activity due to the agglomeration and shielding effects in the p...
