Effect of membrane pore size on the particle fouling in membrane filtration

Effect of membrane property and operating conditions on phytochemical properties and permeate flux during clarification of pineapple juice

“…It could be due to the higher permeate flux leading to higher concentration polarization and more attached solute to the membrane surface. The results were in agreement with Hwang et al (2008). They found that the larger pore may have more opportunities to be blocked by particles.…”

“…The membrane with larger pore size tends to be more susceptible to fouling because more severe pore blocking occurring in the larger membrane pores. It also can be expected that more particles can accumulate in larger pore volume (Hwang et al, 2008). In the case of UF membranes, the flux (8.9 lm À2 h À1 ) of 30 kDa membrane was much lower than that of 100 kDa membrane (18.7 lm À2 h À1 ).…”

Raw Juice Concentration by Osmotic Membrane Distillation Process with Hydrophobic Polymeric Membranes

“…The suspended particles, bigger than 0.2 μm, can block pores of 0.45-μm membranes leading to flux decrease. In the literature, it was highlighted that membranes with a bigger pore size are more vulnerable to fouling (Hwang et al 2008;Kujawski et al 2013). Alike results were obtained by Kujawski et al (2013).…”

“…Permeate fluxes for membranes with smaller pore sizes of 0.10 and 0.20 μm were slightly higher than for membranes with a bigger pore size of 0.45 μm; however, the differences are marginal. This phenomenon was also described in the literature (Hwang et al 2008). For membranes with a smaller pore size, the permeate fluxes were marginally higher which can show lower surface fouling and pore blocking than in the case of the membranes with a higher pore size (Fig.…”

Ultrafiltration membrane fouling caused by extracellular organic matter (EOM) from Microcystis aeruginosa: Effects of membrane pore size and surface hydrophobicity

“…All of the properties can influence the membrane fouling to some extent. Kwang et al [18] has investigated the effect of pore size on the microfiltration membrane fouling caused particles, and found that the loose membrane was subjected to more severe fouling. Costa et al [19] compared the humic acid fouling of membranes with different pore sizes, and found that the tight membrane displayed stronger anti-fouling ability.…”
