Modelowanie matematyczne staje się nieodłącznym narzędziem w projektowaniu i obsłudze oczyszczalni ścieków z osadem czynnym. Opublikowany w 1987 roku model ASM1 otworzył nowe możliwości w dziedzinie tworzenia i wykorzystania modeli biokinetycznych oczyszczania ścieków i stał się standardem w modelowaniu procesu osadu czynnego. Model oczyszczalni ścieków składający się z podmodeli osadu czynnego i procesów towarzyszących (np. sedymentacji) zaimplementowany w odpowiednim oprogramowaniu ma wiele zastosowań w nauce oraz w praktyce inżynierskiej. Warunkiem uzyskania zadowalających wyników symulacji (eksperymentu prowadzonego na modelu) jest skalibrowanie wykorzystywanego modelu. Przebieg kilkuetapowej procedury kalibracji zależy od przeznaczenia modelu i polega na scharakteryzowaniu go na podstawie dostępnych danych określających właściwości modelowanego obiektu. Brak jednoznacznych zasad kalibracji modelu i dowolność w sposobie jej wykonania często uniemożliwiają porównanie jej jakości i efektów. Próby usystematyzowania kalibracji modeli procesów oczyszczania ścieków podjęli się autorzy tzw. protokołów kalibracyjnych, podając wytyczne kalibracji modelu. Zasady kalibracji omówione w poszczególnych protokołach kalibracyjnych są zbliżone pod względem kolejności i celów etapów kalibracji, różną się jednak pod względem metodyki. Z tego powodu konieczne jest opracowanie ujednoliconego zbioru wytycznych kalibracji modeli procesów oczyszczania ścieków.

Mathematical modelling has become an inherent part of the design and operation of activated sludge systems. The ASM1 model is the international standard for modelling of the activated sludge process. The model was published in 1987 to bring new opportunities for development and application of biokinetic models of wastewater treatment processes. Wastewater plant model consisting of submodels of the activated sludge process and accompanying processes (eg. sedimentation) may be implemented in relevant software for various engineering and scientific applications. In order to obtain acceptable results of simulation (experiment on model) the applied model must be calibrated. The steps within the calibration procedure in which model is characterized based on available real-world plant data may vary depending on the goal set. The lack of standard approach in performing the calibration study makes it virtually impossible to compare different calibrations with each other. In order to bring guidance to the modelling of wastewater treatment processes systematic calibration protocols have been proposed. The calibration procedures presented in the calibration protocols are similar in terms of goals and order of calibration steps but they introduce different methodology. Hence, it is necessary to develop unified calibration protocol for wastewater treatment processes models.
