The most often used system in aerobic biological wastewater treatment is the system “biological reservoir – sedimentor”. The necessary condition for obtaining a good operative control is an adequate process model to be available. The aim of this paper is modelling of a process, carrying out a system “biological reservoir – sedimentor”, and consequent parameter identification. In order to obtain a model with higher degree of accuracy, the process of wastewater treatment is considered as object with distributed parameters. Shifted two – dimensional Haar orthogonal functions are used for parameter identification of the process. The implementation of these orthogonal functions reduces the problem to a computationally convenient form. The algorithm is efficient and simple in form.
