Plasma surface modification of polypropylene microfiltration membranes and fouling by BSA dispersion

Fabrication and characterization of a novel TiO2 nanoparticle self-assembly membrane with improved fouling resistance

“…It has been confirmed by Yana et al [36] that the protein irreversible adsorption on the membrane surface will decrease the porosity and pore size, which will have influence on BSA rejec- Table 3 Anti-fouling properties of blend membranes and self-assembly membranes. tion ratio.…”

“…After TiO 2 nanoparticles are deposited on the membrane surface, the hydrophilicity of membrane surface is improved and free water fraction is increased. Consequently, the protein irreversible adsorption on membrane surface is reduced [36] and the decrease of pore size and porosity is restrained. BSA rejection ratios of TiO 2 self-assembly membranes are under 94%.…”

Surface hydrophilic modification of RO membranes by plasma polymerization for low organic fouling

“…Yu et al has used air plasma to treat the hollow fiber microporous membrane (PPHFMMs) to investigate the effect so fair plasma treatment on the membrane fouling in a submerged membrane-bioreactor [15,16]. Other works involving plasma surface modification include use low temperature NH 3 plasma to treat the polypropylene microfiltration membrane [24] and plasma polymerization of polyacrylic acid (PAAc) and hydroxylethyl-metacrylic acid (HEMA) to improve the fouling resistance of PES membranes [25]. Plasma treatment was used by Kim and Kim [26] to modify the hydrophobic RO membrane support layer, i.e.…”

Controllable modification of polymer membranes by long-distance and dynamic low-temperature plasma flow: Treatment of PE hollow fiber membranes in a module scale

“…It was found that the modified membrane surfaces showed better regeneration behavior and the amount of protein adsorption decreased by over 50% for the treated membranes compared with the unmodified membranes. Yan et al [14] studied the effects of NH 3 plasma treatment on the PP hollow fiber membrane fouling during the filtration of BSA dispersion. It was observed that flux recoveries after water and caustic cleaning for the NH 3 plasma-treated PP hollow fibers for 1 min were 51 respectively higher than those of the virgin membrane.…”
