Figs. 9 and 10 indicate the effects of upstream pressure and
flowrate on permeation flux for ultrafiltration using DI water,
respectively. As seen in Figs. 9 and 10, with the increasing upstream pressure and the flowrate, the water permeation flux
both increased. Figs. 9 and 10 also showed that the PVDF–PVP
membranes had larger water permeation flux than the original
PVDF membranes. Based on the contact angle values in Table 2,
those results were attributed to the improvement of hydrophilicity.
Furthermore, the pore size of PVDF–PVP membranes turned
larger after modification as seen in Fig. 6, which also had contribution
to higher water permeation flux.
