Grey-box Dynamic Model of a Drinking Water Treatment Plant

In the paper a concept of a general reaction volume in a drinking water treatment plant (DWTP) is introduced, where several such volumes need to be stacked in series with corresponding input chemicals used in them to finally represent the entire plant. A general case in which a reaction volume is not fixed is elaborated. The overall derived plant model is of a grey-box form with a small number of tunable parameters, which is beneficial for adaptation to a particular DWTP based on its laboratory and on-line measured data. The developed mathematical models of reaction volumes are stacked and inputs in different volumes selected such that they represent a concrete DWTP for which a decision-support system is being developed. A preliminary validation is performed against laboratory-determined plant input-output data.
