Analysis results of lithium chloride concentrations, which were measured during tracer test performed in wastewater treatment (WWT) plant placed in Kędzierzyn–Koźle, Poland, are presented in the paper. The considered WWT plant operates with a five-stage Bardenpho system for organic content reduction within activated sludge process (ASP). One of the significant factors, which have an impact on the efficiency of the ASP in a biological reactor, is its hydraulic behavior. In this study theoretical and actual retention times were determined by using of mathematical modeling. Three single and multistream dispersion models were applied, i.e. Tanks-in-Series, Extended Tanks-in-Series and a model based on the MARTIN method. Using the last model it was possible to identify multiple wastewater flows in the reactors, which include: main flow and short circuiting flows. Furthermore, it was stated that the theoretical retention times differ from the actual values, obtained through mathematical modeling.
