Abstract

The effect of humic acid (HA), and the roles of microfiltration (MF), PES (polyethersulfone) beads adsorption,and photo-oxidation were investigated in hybrid process of ceramic MF and PES beads loaded with titanium dioxide(TiO₂) photocatalyst for advanced drinking water treatment. Those were compared and studied in viewpoints of membranefouling resistance (R_f), permeate flux (J), and total permeate volume (V_T). Because membrane fouling increased dramaticallyas decreasing HA, R_f increased and J decreased, and finally V_T was the highest at 2 mg/L HA. In the experiment to investigatethe roles of photo-oxidation and adsorption at humic acid 4 mg/L and 6 mg/L. In both conditions, R_f was the lowestand V_T was the highest in MF + TiO₂ + UV process. The average treatment efficiencies of turbidity and dissolved organicmatters were the highest in MF + TiO₂ + UV process, too.
