Our Objective

WRF will identify, assess, and make recommendations to improve sustainable wastewater nutrient removal and recovery technologies. WRF will provide information to help agencies meet receiving water body requirements and other wastewater treatment goals, such as climate change, sustainability, cost-effectiveness, and reliability. The research will inform regulatory decision making, and help practitioners comply with increasingly high levels of nitrogen and phosphorus removal, with a focus on improving plant performance.
