Preparation and Performance Studies on Polyethersulfone Ultrafiltration Membranes Modified with Gelatin for Treatment of Tannery and Distillery Wastewater
In this study polyethersulfone ultrafiltration membrane were prepared with the modifier gelatin at 0, 5, 10, 15 and 20 wt % using DMF as solvent by phase inversion process. Morphologies and characteristics of the membranes were investigated through the methods of SEM, XRD, contact angle measurements. The performance of the modified membrane for the treatment of leather and distillery wastewater...
متن کاملModified polyethersulfone membranes for micellar enhanced ultrafiltration of chromium
Separation performances of micellar enhanced ultrafiltration process in Cr(III) and Cr(VI) removal has been evaluated. The neat as well as sulfonated and aminated derivatives of polyethersulfone were tested as the material for membrane preparation while hexadecylpyridine chloride and sodium dodecyl sulfate served as surfactant. It was shown that modified membranes can better reject both forms o...
متن کاملPreparation of blend hydrophilic PSF-SPEEK ultrafiltration membranes for oily wastewater treatment
Membrane separation is known as an efficient technique for the oily wastewater treatment. Therefore, in the present study, sulfonated poly (ether ether ketone) (SPEEK) was introduced into the polysulfone (PSF) solution in order to enhance the hydrophilicity and the membrane structure for the oil–water separation. The hollow fiber membranes were fabricated via a phase-inversion process. The memb...
متن کاملPolysulfone Ultrafiltration Membranes Modified with Carbon-Coated Alumina Supported NiTiO2 Nanoparticles for Water Treatment: Synthesis, Characterization and Application
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 ...
متن کاملPreparation, Characterization and Application Studies of PVDF- PS Ultrafiltration Membranes
Polyvinyledenefluoride–polystyrene (PVDF/PS) blend ultrafiltration membranes were prepared using phase inversion technique. Casting solutions were prepared with different compositions of polyvinylidene fluoride (PVDF) and polystyrene (PS) both in the presence and absence of the additive, polyvinylpyrolidone (PVP) using dimethylacetamide as solvent. The effects of compositions of PS and concentr...
