Water resource recovery facilities (WRRFs) across the United States are facing demands to remove nutrients. Existing nutrient removal and secondary WRRFs alike are challenged to optimize their WRRFs to reduce nutrients discharged into receiving water bodies. This project developed a comprehensive guidance tool that WRRF staff and others can use for optimizing WRRFs to meet one or more fundamental objectives: (1) reduce nutrient discharge levels, (2) increase reliability, and (3) reduce costs. The guidance tool provides a stepwise progression starting with the current treatment processes and advancing to a list of nutrient removal optimization strategies. The comprehensive guidance documents presented in the report have also been summarized into a standalone, user-friendly web tool. In addition to these resources, the research team hosted a 13-part webcast series covering all facets of nutrient management. Results from the audience polls are incorporated into the report and available as a project paper. Published in 2023.

Internal recycles, such as reject water and sidestreams from solids processing WRRFs can impact nutrient removal efficiency as well as create nuisance conditions. Managing these recycles can improve nutrient removal...
