Nanotechnologies, 'the engine of the next Industrial Revolution', represent the new wave of research for chemical and industrial innovation. However, with any new technology or compound, comes the threat of harm to humans and natural ecosystems. Research into the environmental effects, as well as the ethical, legal, and social implications of nanotechnologies and nanoproducts has never been more important. ""Nanotechnologies for Water Environment Applications"" provides the current status of synthesis and characterization of nanomaterials, as well as the environmental effects of nanotechnology. This publication specifically targets the major applications of nanotechnologies in various water environments; issues related to the fate and transport of nanomaterials in aquatic environments; engineered nanomaterials as emerging contaminants in water; the environmental risks, and related management, of nanomaterials. Extensive up-to-date references are provided. This book will be useful to undergraduate and graduate students of engineering, educators, scientists, engineers, government officers, decision makers, process managers, and practicing professionals.

This work provides a tool for engineers or decision-makers to evaluate the applicability of Zero-valent iron (Fe0) and give them the technical solutions about the engineering application of Fe0 to contaminated sites. Written from both theoretical and practical viewpoints, this book covers the comprehensive principles, latest research findings, and innovative development of Fe0 in hazardous waste and inorganics removal. Moreover, the approaches of design, installation and performance evaluation of Fe0-based PRBs are also covered.
