Because low pressure and temperature were necessary, membrane distillation (MD) was used to concentrate phenolic -rich solution. The fabricated PVDF/TiO2 membranes with and without silane modification were evaluated for their separation abilities. Prior to blending into the PVDF casting solution, the TiO2 nanoparticles were either used as it is or hydrophobic modified. the PVDF/TiO2 membrane with silane modification had a water contact angle of (118oC), whereas the membrane incorporated with hydrophobic modified TiO2 (PVDF/FTPs) had nearly super hydrophobicity (122 oC). Using a phenolic -rich solution, the separation performance of these membranes was evaluated in MD. Significant phenolic comp ounds rejection was shown by all membranes, ranging from 65% to 99%. In comparison to the unmodified PVDF/TiO 2 membrane, the modified PVDF/TiO 2 with silane solution and PVDF/FTPs membranes displayed flux (8.9 and 10.5 lit/m 2.h, respectively). The maximum p ermeation flux, however, was attained by the PVDF/ FTPs membrane because it formed a large amount of porosity during phase inversion without being disturbed by silane alteration.
