Our Objective

WE&RF will identify, assess, and make recommendations to improve sustainable wastewater nutrient removal and recovery technologies. WE&RF 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.
