Abstract

Membrane surface modification through UV-grafting method was studied and optimized using response surface methodology (RSM) approach. Sulfonated-polysulfone (SPS) membrane was modified through grafting process by employing methacrylic acid (MAA) monomer solution under the exposure of UV light. The parameters used were the concentration of MAA in the range of 0-6 wt% and UV activation time of 0-50min. The optimized parameters from RSM were 2.61 wt% of MAA and 21.10min of UV activation time. The optimized water permeability obtained was 8.75 Lm-2h-1bar-1, while the rejection percentages for humic acid, NaCl and MgSO4 solution were 95.0%, 65.7% and 48.3%, respectively.
