Résumé
A conceptual model of the overall process of metal bioleaching from sewage sludge has been developed on the basis of experimental observations. Sludge pH was identified as the parameter which controls bacterial growth and thus the overall process. Quantitative relationships among the various process parameters were incorporated in the conceptual model, giving a mathematical model for the process. Bacterial growth, sulfate concentration and pH profiles simulated using the model were found to match experimental observations. The degree of solubilization of each metal was found to depend on the sludge pH and the type of the sludge and is given as a set of solubilization curves.
