This book aims to structure, in a complete and sequential way, the mainstream technical knowledge which is related to eutrophication control. The book considers the development of innovative technologies for phosphate removal, while supporting the restoration of currently degraded lakes and reservoir systems. In addition, this book contains key-aspects of future benchmark interests being specially framed under the ongoing development of a circular economy. In particular, the book will contribute to a better understanding of the problem of internal P-loads and P-sources disposition towards a more effective control of nutrients' enrichment in lakes. The chemical routes and environmental fate of such lake nutrients will be viewed in the light of innovative technologies (engineering dimensions) and circular economy perspectives (economics dimensions). The main theme extends to an economic appreciation of environmental polluted aquifers. The book will appeal to an interdisciplinary audience, covering a wide spectrum of scientific fields, such as environment, physical chemistry, surface chemistry, interfacial phenomena, coastal engineering, bio-engineering, environmental policy makers, and economists.

Dr. Grigorios L. Kyriakopoulos (PhD) is Teaching and Research Associate at the School of Electrical and Computer Engineering, National Technical University of Athens (NTUA), Greece. He has accumulated almost 25 years research and teaching experience at NTUA, Hellenic Naval Academy (2 years), Hellenic Merchant Marine Academy (2 years), and School of Pedagogical and Technological Education of Athens (4 years).
