Good Modelling Practice (GMP) – Guidelines for Use of Activated Sludge Models

The Task Group is officially hosted by the IWA Specialist Group on Modelling and Integrated Assessment and has full support from the Task Group on Mathematical Modelling for Design and Operation of Biological Wastewater Treatment. Mathematical modelling of activated sludge systems is used widely for research, plant design, optimisation, training, and model-based process control. The quality of simulation studies can vary strongly depending on the project objectives, resources spent and expertise available. Consideration has to be given to the model accuracy and the amount of time required carrying out a simulation study to produce the required accuracy. A great variety of approaches and insufficient documentation make quality assessment and comparability of simulation results difficult or almost impossible. A general framework for the application of activated sludge models is needed in order to overcome these obstacles.
