A model is a representation of a system that is used to predict the behaviour of the system. The application of dynamic models of wastewater treatment processes depends on fundamental porcess knowledge, synthesis of this knowledge into a model, and implementation of the model in a simulator. These three have converged to provide tools that can be used for process design, analysis, and operation. By using models that encompass fundamental biological and chemical processes, a better understanding of the performance of a wastewater treatment facility is available. Applications of the models presented in this paper show that better understanding and predictive capability can be used to improve plant performance or reduce the cost of plant oeprations or upgrades. At a municipal plant, a proposed upgrade based on modelling resulted in significant capital cost savings, in the order of
