Enhanced Anti-Fouling Behavior and Performance of PES Membrane by UV Treatment

An easy method to prepare hydrophilic PES membranes with anti-fouling properties was developed by UV-polymerization of poly vinyl pirrolidone (PVP) on membrane surfaces. The modified surfaces were analyzed ATR-FTIR, and the new nature determined contact angle measurements. novel prepared using Rhodiasolv® Polarclean as a green solvent compared control membrane, without exposure at hydrophilization procedure. influences UV lamp distance (15 30 cm) time (0 cm 60 evaluated. All characterized in terms surface morphology, porosity, pore size, pure water permeability (PWP). treated resulted an increase hydrophilicity improved performances PWP foulant rejection. In particular, test performed solution 100 mg/L humic acid (HA) model foulant. UV-treated efficiency, commercial showed recovery about 97%, confirming that these can be applied wastewater treatment.
