Guidelines for Using Activated Sludge Models

The IWA Task Group on Good Modelling Practice (GMP) has analysed current practice and experience on the use of activated sludge models. The group developed a framework to make modelling more straightforward and that helps structuring the interaction between modellers and the project stakeholders. The GMP protocol is a synthesis of existing procedures, and contains five major steps: (i) Project definition, (ii) Data collection and reconciliation, (iii) Plant model set-up, (iv) Calibration and validation, and (v) Simulation and result interpretation.
