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.

The research team will present a comprehensive webcast series to develop nutrient optimization guidelines for operational best practices. Presentations will explore how to optimize nutrient removal to reduce costs, increase efficiency, and reduce nutrient discharges. All webcasts in the series are designed to be interactive with audience participation, and attendees will have access to helpful fact sheets, case studies, optimization guides, and decision trees.
