This paper outlines a framework for combining the use of wastewater process models used to design treatment plants with real-time process information from online nutrient analyzers and probes. The benefit of this framework is to improve effluent quality and the utility of the information provided by the instruments and reduce operating costs. A case study is discussed to illustrate key concepts. Real-time optimization of the following five key functions of BNR facilities is addressed: dissolved oxygen control, nitrification, denitrification, biological phosphorus removal, and solids separation. Additional work is needed to develop algorithms that account for the complex interactions between nitrogen and phosphorus removal and can make quick decisions about how to best optimize the process at any given time.
