Abstract

Abstract

Permeable Reactive Barrier (PRB) technology is one of the most popular technologies for in-situ groundwater or soil remediation. A key task of design and installation is to calculate the thickness of the PRB. Most of the existing models of calculating the PRB thickness only consider the single species or the reaction barrier itself, with little consideration of a variety of contaminants and the combination of the aquifers. The response to PRB and aquifer multi-domain system, the convection dispersion equation of multi-species under one-dimensional condition was established. The analytical solution of the equation was obtained by using a conversion algorithm proposed by related literature, and the formula of the new PRB thickness was deduced at the same time, and then the numerical model was built based on the software COMSOL to validate this analytical solution. After comparing the required PRB thickness calculated from this study and previously developed Rabideau models, the aquifer reaction capability is found to be non-negligible for the determination of the required thickness of the PRB especially when the compliance plane becoming far from the PRB exit face. For the remediation multiple species sharing a single parental species, the correctness in the boundary and the domain conditions are crucial to estimate the effective thickness of a PRB. The proposed analytical solution provides meaningful designing insights for the PRB design and installation.
