The dissolved oxygen is a key parameter for biological processes at wastewater treatment plant. The dissolved oxygen tracking problem is one of the most complex and fundamental issue of biological processes. The paper proposes a new multiregional control strategy for dissolved oxygen tracking problem. The aeration system is included in overall control structure. The control mechanism within the operating point area is based on PI controllers with the Takagi-Sugeno-Kang method of defuzzification. The proposed control strategy is designed and tested based on the real data records. It is applied to biological wastewater treatment plant at Nowy Dwor Gdanski, Northern Poland and is validated by simulation.
