dc.description.abstract | Ultrafiltration membrane nowadays has been increasingly used in drinking water treatment as alternative technology to conventional filtration to remove Natural Organic Matter (NOM). Efforts on how to minimize fouling, maximize flux and rejection are always on motion. This study is aimed to improve the performance of membrane by combining membrane coated photocatalyst TiO2 under UltraViolet exposure. The experiments are carried out using ceramic disc membrane which is high temperature resistant, using humic acid solutions as model substances representative of naturally occuring organic matter, they are aimed to identify the significance performance between TiO2 coated membrane and naked membrane.
A commercial humic solution was subject to UF Fractionation to study about molecular weight distribution affected during the operation of membrane. 1 kD, 15 kD and 50 kD membranes were used to demonstrate the effectivity of the coating and UV irradiation. For all TiO2-UV254 membranes used in this research exhibit the more flux decline with similar quality compare to naked membrane. Although the UF system is able to remove a significant portion amount of humic acid particles, the combination with photocatalysis exerts low performance in terms of flux. The molecular weight distribution alteration during photocatalysis appears to be the cause of the low result. Thus, TiO2 coating combined with UV254 irradiation are not better for operation in removing natural organic matter. | en |
