This volume includes selected contributions presented during the 2nd edition of the international conference on WaterEnergyNEXUS which was held in Salerno, Italy in November 2018. This conference was organized by the Sanitary Environmental Engineering Division (SEED) of the University of Salerno (Italy) in cooperation with Advanced Institute of Water Industry at Kyungpook National University (Korea) and with The Energy and Resources Institute, TERI (India). The initiative received the patronage of UNESCO World Water Association Programme (WWAP) and of the International Water Association (IWA) and was organized with the support of Springer (MENA Publishing Program), Arab Water Council (AWC), Korean Society of Environmental Engineering (KSEE) and Italian Society of Sanitary Environmental Engineering Professors (GITISA). With the support of international experts invited as plenary and keynote speakers, the conference aimed to give a platform for Euro-Mediterranean countries to share and discuss key topics on such water-energy issues through the presentation of nature-based solutions, advanced technologies and best practices for a more sustainable environment. This volume gives a general and brief overview on current research focusing on emerging Water-Energy-Nexus issues and challenges and its potential applications to a variety of environmental problems that are impacting the Euro-Mediterranean zone and surrounding regions. A selection of novel and alternative solutions applied worldwide are included. The volume contains over about one hundred carefully refereed contributions from 44 countries worldwide selected for the conference. Topics covered include (1) Nexus framework and governance, (2) Environmental solutions for the sustainable development of the water sector, (3) future clean energy technologies and systems under water constraints, (4) environmental engineering and management, (5) Implementation and best practices Intended for researchers in environmental engineering, environmental science, chemistry, and civil engineering. This volume is also an invaluable guide for industry professionals working in both water and energy sectors.

Provides a comprehensive updated framework on the emerging topic of Water-Energy Nexus and its perspectives on the future of the nexus agenda Discusses latest advances in environmental science and technology from diverse backgrounds aiming for the sustainable development of Water and Energy sectors Demonstrates how science, novel technologies and policies can contribute to promoting a more sustainable environment using a nexus approach Maximizes reader insights into emerging environmental issues and challenges in Water and Energy issues with examples of the nexus approach in practice from different regions of the world

Autorentext
Prof. Choo received his Ph.D. degree from Seoul National University, Korea in 1996 and since then has been working on membrane science and technology for water and wastewater, pursuing innovative solutions for sustainable water production and reuse. His recent research interests include membrane electro-oxidizers and quorum quenching membrane bioreactors. He is currently keen to find synergistic options for water-energy nexus issues, using membranes in conjunction with physicochemical/biological strategies, such as iron oxide adsorption, photocatalysis, electrocatalysis, and microbial quorum quenching. He has been actively involved in academic societies, such as International Water Association, Korean Society of Environmental Engineers, and Membrane Society of Korea, and Korean Institute of Chemical Engineers, as an active board/editorial member.
Prof. Vincenzo Naddeo is associate professor at Department of Civil Engineering of theUniversity of Salerno (Italy) where he drives research activities at the Sanitary Environmental Engineering Division (SEED). He was visiting professor at University of Washington (2009) and Yamaguchi Uniersity (2016). He is Associate Editor of the Euro Mediterranean Journal for Environmental Integration (Springer) and co-founding Chair of the conference series WaterEnergyNEXUS. He presently serves on the editorial board of several ISI journals including Scientific Reports (Nature Research), Heliyon (Elsevier), PeerJ (Life, Bio, Environment & Health Sciences) and he is actively involved in a variety of scientific organizations, funding agencies, and European networks. Dr. Naddeo has (co-) authored over 170 refereed publications in ISI journals, congress proceedings and book volumes. He holds 4 patents on water and wastewater treatments by sonolisys and 1 patent on novel electronic nose (e.Nose).
Prof. Balakrishnan 's major interests are development and dissemination of environmentally sound technologies, with emphasis on membrane development and applications. She has directed various externally funded projects involving international consortia, as well as projects with industrial applications and is also active in developing and effecting technology transfer of membrane processes and products to industry. Dr Balakrishnan's research has evolved around (a) Microfiltration /ultrafiltration / pervaporation process development (b) new membrane materials (c) value-added utilization of wastes. Primarily, the work is targeted at providing solutions to specific problems with strong local relevance (e.g. advanced wastewater treatment) and is associated with addressing the concerns of major Indian industries (e.g. sugar factories for improved clarification in sugar production process, new applications of waste bagasse fly ash). The research activities are primarily directed at users' needs with doctoral and masters students concurrently contributing to advancing the state-of-the-art in these fields. She has over 100 publications in ISI journals and conferences to her credit and four patents under processing.
