Municipal wastewater treatment is essential to control the environmental impacts of human behavior. It reduces the emissions of organic matter and nutrients. The continuously changing flow and composition makes it challenging to meet the severe discharge limits.

Modelling is a powerful tool for optimizing wastewater processes. Once implemented and calibrated, a model offers many advantages such as saving significant costs by predicting the outcome of operational changes, as well as by performing an energy cost analysis.

The benefits of using models are:

• Determination of maximum flow conditions
• Preparation for upcoming regulations
• Identifying bottlenecks in the system
• Equipment evaluation
• Energy saving and chemical usage changes evaluation
