Abstract

As water resource recovery facilities (WRRFs) continue to face nutrient management challenges, there is a need for guidance on the wide range of nutrient control techniques. Through this project, a road map will be developed to assist WRRFs in optimizing nutrient removal to reduce costs, increase efficiency, and reduce nutrient discharges.
