Biological destruction of CCI(4): II. Kinetic modeling.
A denitrifying consortium capable of transforming carbon tetrachloride (CCI(4)) was cultured from an aquifer soil sample from the U.S. Department of Energy's Hanford Site in southeastern Washington State. A mathematical description of the kinetics of CCI(4) destruction by this microbial consortium is presented, and its prediction are compared to experimental data. The model successfully predicted the concentrations of acetate, nitrate, nitrite, biomass, and CCI(4) for all 12 experiments (a total of 60 concentration-vs.-time data sets). In addition, no statistically significant interactions exist between parameter values and individual test conditions. The ability of the model to predict the results of a treatability test for CCI(4) degradation in Hanford groundwater, without adjusting any model parameters, is discussed.
