Progress in Research on Application of Fe0 Permeable Reactive Barrier to In-situ Remediation of Groundwater Contaminated with Chlorinated Hydrocarbons

Fe0 Permeable reactive barrier is a promising new technology for remediation of groundwater contaminated with chlorinated hydrocarbons. In theory, the application of PRB presents a series of advantages in relation to pump-and-treat, including low operation costs, low maintenance, high efficiency and low on-going energy requirements. However, it still has some shortcomings that call for further research and improvement. The authors introduce structure and characteristics of installation and in-situ application of the permeable reactive barrier and review progresses in research on the system in the paper.
