The Blue Plains Wastewater Treatment Facility in Washington, D.C. is the largest advanced wastewater treatment plant of its kind in the world, treating 330 million gallons of wastewater every day. Like all wastewater treatment plants, Blue Plains produces nitrogen. Because the plant discharges directly into the Potomac River Estuary it has to meet some of the most stringent nitrogen standards in the United States. To meet these standards, DC Water built an Enhanced Nitrogen Removal (ENR) Facility. Watch this video to learn why KSB’s pumps were selected for one of the most-advanced ENR systems in the world.
