Over the past few years, significant research has been conducted into the development of polymeric nanocomposite membranes to increase environmental sustainability and to demonstrate their benefits for commercial water treatment and desalination applications. Polymer Nanocomposite Membranes for Water Treatment and Desalination: Recent Developments, Future Opportunities and Sustainable Applications presents the latest research findings in this important field. The book summarizes current advances in the production, characterization, and applications of these membranes for water treatment and desalination. Bio-composite alterations, functional group additions, and nanomaterial assemblies are also examined in depth. The current breakthroughs in reverse osmosis, oil removal, heavy metals removal, dye removal, photocatalytic degradation of organic contaminants, and pesticide removal from wastewater are also discussed. Additionally, the book also highlights bacteria removal by polymeric nanocomposite membranes as well as the major benefits and drawbacks of various adsorbent materials. Special emphasis is also placed on the adsorption mechanism, which includes chemisorption and physisorption. The book will be a valuable reference source for academic and industrial researchers, as well as early career researchers who are working in the research and development of polymer nanocomposite membranes for water treatment and desalination.
