Preparation, characterization and performance enhancement of polysulfone ultrafiltration membrane using PBI as hydrophilic modifier

Removal of heavy metal chromium from tannery effluent using ultrafiltration membrane

“…This constant value indicates the completion of compaction. This may be due to the fact that the walls of the pores become closer, denser, and uniform resulting in reduction in pore size as well as the flux during compaction (Eren et al 2015). Furthermore, the polymeric chains reorganize under hydraulic pressure during compaction leading to change in the structure with a lowered volume of porosity.…”

Preparation and characterization of novel microporous ultrafiltration PES membranes using synthesized hydrophilic polysulfide-amide copolymer as an additive in the casting solution

“…Eren et al prepared PSf composite UF membranes by blending of poly [2,2 0 -(m-phenylene)-5,5 0 -dibenzimidazole] (PBI). The resulted membrane properties such as hydrophilicity, porosity and thermal stability can be considerably enhanced with the incorporation of PBI [26]. Totally, it could be concluded that addition of the polymers with multifunctional groups such as carboxylic acid, amine, hydroxyl, sulfide, sulfonate, nitro, carbonyl and etc.…”

Synthesis, characterization and performance studies of polysulfone/bentonite nanoparticles mixed-matrix ultra-filtration membranes using oil field produced water

“…Arthanareewaran et al [33] studied the effect of LiCl and SiO 2 separately in cellulose acetate membranes and found that marginal improvement in pure water flux from 29.60 to 34.28 L m -2 h -1 was obtained when additive dosing kept at 5 wt%. Eren et al [34] prepared PSf membrane by blending poly[2,2'-(m-phenylene)-5,5'-dibenzimidazole] in casting solution and found that marginal pure water flux improvement in composite membrane was observed over PSf membrane.…”
