Development of novel SiO2–GO nanohybrid/polysulfone membrane with enhanced performance

Preparation and characterization of graphene oxide/TiO2 blended PES nanofiltration membrane with improved antifouling and separation performance

“…Membrane fouling as one of the main drawbacks of membrane processes has various disadvantages such as flux decline, increment of operation and maintenance costs, and membrane degradation [34]. Therefore, great attention has been focused on the modification and improvement of antifouling capability of membranes.…”

“…The FRR value of the bare PES membrane was 75.2%, and the R ir of this membrane was the main part of the total fouling (as high as 80% of the total fouling). The irreversible fouling is brought by rigid adsorption of protein molecules on the surface or entrapment of protein molecules in pores, while reversible fouling arises from reversible protein adsorption and can be removed by simple hydraulic cleaning [34]. For PES membranes blended with 0.1 wt.% TiO 2 , GO and rGO/TiO 2 , FRR values increased to 87.4, 90.7 and 96.8%, respectively.…”

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

“…and polymeric additives [e.g., polyethylene glycol (PEG), polyvinylpyrrolidone (PVP), etc.] are blended with casting solution to obtain desired membrane properties [27][28][29][30][31]. Song et al [27] studied the effect of silica nanoparticles in PSf membrane and found that the pure water flux (PWF) of membrane containing 1.0 wt% silica was 2.3 times higher than that of PSf membrane.…”

“…Song et al [27] studied the effect of silica nanoparticles in PSf membrane and found that the pure water flux (PWF) of membrane containing 1.0 wt% silica was 2.3 times higher than that of PSf membrane. Wu et al [31] prepared the PSf-silica membranes and found that the water flux was nearly twice that of plain PSf membranes when silica in the membranes was 0.3 wt%. Chakrabarty et al [3] studied the effect of PVP with different molecular weight on structure and permeation properties of PSf membrane and reported that number of pores and pore area were increased with a molecular weight of PVP.…”

Suppressing Salt Transport through Composite Pervaporation Membranes for Brine Desalination

“…GO nanosheets are known to improve the anti-fouling property for the mixed matrix filtration membranes [18,[20][21][22][23]. This is ascribed to the improved membrane's hydrophilicity due to the …”
