Abstract: Membranes play a critical role in gas separation, resource recovery, advanced water treatment, and wastewater recycling.
However the demands placed on membranes used in these applications include relatively aggressive conditions arising from a diverse
composition of materials presented to the membranes with extensive bacterial activity, mechanical stress, and a range of chemicals used
to clean membranes. Advances in membrane composition and coating are required to meet these demands. The proposed effort addresses
this need in developing new membrane materials and surface treatments based on advances in nano-chemistry designed to increase membrane
strength, reduce fouling, and improve performance. While the most intense areas of research in recent decades focused on the incorporation
of advanced materials to the currently available membranes to improve their performance, recent studies introduced an impressive
breakthrough toward application of novel nanostructured materials that can outperform the existing membranes due to their superior
performance and low energy requirements. This paper provides an overview of recent advances in nano-hybrid membranes
(NHMs) and their potential applications for advanced water treatment. Furthermore, the key challenges in their full-scale applications and
the research needs for overcoming these barriers are also discussed.
