Abstract

Kinetic models for bio-oxidation are presented. The bacterial oxidation of ferrous iron is shown to follow competitive inhibition kinetics. Good agreement is obtained between the prediction of the steady state data from continuous culture using off-gas analysis. However when the oxygen utilization rate is measured off-line in the biological oxygen monitor, BOM, different values of the parameters are necessary in order to fit the data. Batch data are not predicted very well by the model. But using values of the parameter, q_O2^max, from BOM measurements at high ferrous concentrations, it is possible to predict batch performance.
