The wastewater treatment plant (WWTP) is a dynamic, very complex system, in which the most important control parameter is the dissolved oxygen (DO) con-centration. The air is supplied to biological WWTP by the aeration system. Aera-tion is an important and expensive activity in WWTP. The aeration of sewage ful-fils a twofold role. Firstly, oxygen is provided as the main component for biolog-ical processes. Secondly, it supports mixing the sludge with the delivered sew-age, which helps to treat the sewage. The paper proposes a model of the aeration system for biological WWTP located in Northeast Poland. This aeration system consists of the blowers, the main collector pipeline, three lines of the aeration with different diameters and lengths and diffusers. This system is a nonlinear dy-namic system with faster dynamics compared to the internal dynamics of the DO at the biological WWTP. Control of the aeration system is also difficult in terms of control of the DO. A practical approach to model identification and validation is proposed. Simulation tests for aeration system at Matowskie Pastwiska WWTP are presented.
