This committee report 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. This book will be beneficial to engineers, scientists, and decision makers involved in applying Fe0for hazardous waste and inorganics removal.
