Project Description and Objectives
Recent improvements in analytical techniques have allowed for the detection of trace levels (ng/L) of emerging contaminants, such as various pharmaceutical, and personal care products (PPCPs) in wastewater effluents, source waters, as well as treated drinking waters. Concern over the potential adverse ecological and human health impacts resulting from the presence of these emerging contaminants leads to the need for technologies developed for their effective removal. Membrane filtration technology is of particular interest due to its efficiency of pollutant removal, but membrane fouling poses a great hindrance in its frequent and widespread applications. However, membrane fouling (manifested as the flux decline) is a critical issue in the membrane process. Recently, different kinds of NPs have been considered as a hydrophilic additive for membranes. The use of TiO2 NPs improves the hydrophilicity of the membrane, decreases membrane fouling, and also can induce self-cleaning activity of fouled membranes under UV irradiation.
In this project, we will make graphene oxide-TiO2 nanocomposite membrane and study its performance for emerging contaminant removal.
