CENTRALIZED DISSOLVED OXYGEN TRACKING AT WASTEWATER TREATMENT PLANT: NOWY DWOR GDANSKI CASE STUDY

The aeration is used in different operations at wastewater treatment plants. The biological processes that are carried out at require sufficiently high dissolved oxygen concentration in order to maintain microorganisms in an activated sludge. The paper proposes a centralized nonlinear model predictive controller of dissolved oxygen tracking and aeration system control. The controller is applied to wastewater treatment plant at Nowy Dwor Gdanski and its performance is compared with the performance of the control system that is currently applied at this site.
