The wastewater treatment plant can be considered as a dynamic large scale complex system, in which the most important control parameter is the dissolved oxygen concentration in the aerobic zone. The air is supplied to this zone by the aeration system. In the paper, both the sequencing batch reactor and the aeration system are modelled and used as plant of control performed by the cascade nonlinear adaptive control system extended by the anti-windup filter. The effect of certain parameters of the adaptive controller on the quality of control is analysed. Simulation results based on real data recorded in the case study plant are included.
