This book presents the select proceedings of 2nd International Conference on Water Technologies 2022. While several efforts are underway, materials form the core of all research activities to develop technologies to mitigate the global challenge of water crisis. This book includes latest scientific dialogues, state-of-the-art developments in terms of emerging materials, technology development aimed toward mitigating various bottlenecks in water treatment, purification, desalination, and sensing with emerging materials. It also discusses diverse materials driven approaches, including theoretical and experimental studies, to address various aspects of this global issue. The book discusses various topics related to nanomaterials for water purification, bio-physical remediation, photocatalysis, membranes, physico-chemical processes, oil-water separation, sensors, and microplastics, etc. The book can be a valuable reference for beginners, researchers, and professionals interested in water technologies and allied fields.
