Simulation: a key component in the development of an integrated computer-based approach to wastewater treatment plant control

This paper describes the basic elements of an integrated computer control system for wastewater treatment plant operation and control. One of the key elements of this approach is the role played by simulation. The dynamic model of the wastewater treatment plant is critical in developing an optimal control strategy. Modelling of large-scale facilities is complicated by the fact that wastewater treatment plants are not only complex in their design but also in their operation. The simulation tool must be able to reflect process and operational details with some accuracy. Results on the application of the simulation tool to several large-scale scale facilities is discussed.<>
