Demonstration of Progressive Carbon Efficient Nitrogen with Biological Phosphorous Removal in a Conventional BNR Facility

The main objective of this project is to integrate carbon-efficient nitrogen (N) removal processes with biological phosphorus (bio-P) removal within a conventional biological nutrient removal system. The study will demonstrate, at full-scale, the use of innovative process control and optimization to (1) maximize influent carbon utilization for N and P removal rather than aerobic oxidation, (2) integrate bio-P removal and shortcut N removal/simultaneous nitrification and denitrification for energy and carbon efficient complete nutrient removal, and (3) implement partial denitrification and anammox for N polishing.
