| Summary: | The filtration performance of coupling modified polyethersulfone (PES) membrane by coupling diazonium reaction and 25 wt.% aniline modified polyethersulfone (APES /PES) blended membrane by radically diazonium reaction for treating of licorice aqueous solution was verified systematically and compared to bare NF PES membrane. The effect of operational pressure and cross-flow velocity on permeation flux and rejection were evaluated. All experiments were employed in a lab scale cross-flow filtration equipment with effective area of 40 cm2. The applied operational pressure and cross-flow velocity were diverse from 6 to 12 bar and 0.5 to 2.5 cm/s respectively. The obtained results of rejection for licorice aqueous solution were between 84.4% to 99.2%. The durability and antifouling performance of membranes were assessed through long-term filtration of licorice aqueous solution. |
