Abstract

Membrane processes are increasingly used in water treatment to meet more stringent water quality regulations. Ultrafiltration (UF) has been widely used for advanced treatment to remove colloidal particles, pathogens, and natural organic matter (NOM). However, due to large pore sizes, UF alone cannot remove the majority of NOM which can lead to disinfection by-products during the chlorination process. In the laboratory, a negatively charged membrane was used to increase the removal rate of NOM through the utilization of electrostatic interactions. The objective of this study was to investigate the effects of NOM hydrophobic and hydrophilic properties on the performance of the UF process using charged membranes and to study the effects of fouling on the membrane caused from these changes.
