Abstract
Bioreduction of chromium (VI) to chromium (III) is considered a viable technology in remediating chromium (VI) contaminated groundwater. Shewanella oneidensis MR-1 (MR-1) is considered effective in reducing chromium (VI) to chromium (III). Reduction of chromium (VI) by MR-1 is defined by a nonlinear, transient, and zero-order reaction kinetic. Currently available transport models are not designed to simulate such reaction kinetics. The objective of this paper is to present a comparative study of three finite element models (FEMs) - the Galerkin FEM (GFEM), the Crank-Nicolson GFEM (CNGFEM), and the Petrov-Galerkin FEM (PGFEM), to predict transport and bioreduction of chromium (VI) in groundwater by employing the transient nonlinear and zero-order kinetic model. Model predictions by the three models were virtually identical and were in good agreement with the experimental results.
