In 2015 WEF released The Nutrient Roadmap with an aspirational goal: The next generation of wastewater treatment has zero net impact with regard to energy use, greenhouse gas emissions and nutrient discharge by 2040. Achieving this goal requires a dedication to overcoming technical barriers, financial constraints, and regulatory disincentives limiting nutrient removal, greenhouse gas emission reduction, and energy neutrality in wastewater treatment. View the Nutrient Primer from WEF.
The focus of these workshops was on side-stream nutrient removal technologies currently in use and the next generation now rolling out. We must meet permit requirements with low cost, energy efficient systems while also keeping an eye on the larger goal. We are turning wastewater treatment plants into resource recovery facilities that harvest valuable products from sewage. This includes removing nutrients and turning them into a valuable resource that goes back into our communities.
