Frankfurt Am Main _ Flughafen Wastewater Treatment Plant, Kelsterbach, Hessen, Germany

Frankfurt Am Main _ Flughafen is an advanced wastewater treatment plant located in Kelsterbach, Hessen, Germany, near Frankfurt Airport. The plant serves a population of approximately 5,919 and is designed to handle a capacity of 90,000 cubic meters per day, with a current discharge volume of 955.38 cubic meters per day. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent German and EU standards. The plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for sensitive areas and large agglomerations. Although serving a smaller population, its high capacity suggests it may also treat industrial or airport-related wastewater. The treated effluent is discharged into local waterways that ultimately drain into the Rhine River basin. The Rhine is a major European waterway supporting diverse aquatic life and providing drinking water for millions. The plant's advanced treatment helps protect this ecologically significant river system from nutrient pollution and other contaminants.

The plant discharges into the Rhine River basin, a major European watershed that flows through Germany into the North Sea. The Rhine supports diverse aquatic ecosystems, including migratory fish species such as salmon and eel. Advanced treatment at this plant reduces nutrient loads, helping to prevent eutrophication in the river and downstream coastal areas.
