     a model-based sensitivity analysis was performed in order to evaluate the importance of the individual operating parameters of a three-phase fluidised-bed biological reactor used for removing mercury ions from wastewater. the parameters analysed involve the immobilised biomass load (bacteria p. putida) on alginate beads, particle size, inlet flow-rate, mercury ion loads in the fed wastewater, and the solid fraction in the reactor. predictions were generated by using pseudo-first-order, michaelis-menten, or pseudo-haldane kinetic models. the results highlight the major influence of the biomass/solid load and of the liquid residence time on the reactor efficiency. also, the resultant significant differences in the model predictions underline the importance of using a more accurate kinetic model for process design and control purposes.
