Determination of Kinetic and Stoichiometric Parameters of Activated Sludge Models

An overview of methods aiming at the determination of selected parameters of activated sludge models has been presented. The attention was paid to the model parameters being the most sensitive and dependent on the composition of biomass and/or substrate. These parameters should be determined experimentally. Methods based on the measurements of oxygen uptake rate are widespread use in this area. For the parameters associated with ordinary heterotrophic organisms the method is wellknown and regarded as standard. At the same time for many parameters associated with polyphosphate accumulating organisms the procedures have not been elaborated so far.
