Proportional-Integral Ammonium-based Aeration Control for Activated Sludge Process

Most of the earlier research working on the aeration control of the activated sludge process (ASP) utilized the fixed dissolved oxygen (DO) concentration control strategy. This strategy typically works at elevated level of aeration to avoid nitrification failure and to meet biological oxygen demand...
