AEROSKOBING RENSEANLAEG - Advanced Wastewater Treatment Plant in Ærøskøbing, Denmark

AEROSKOBING RENSEANLAEG is an advanced wastewater treatment plant located in Ærøskøbing on the island of Ærø in southern Denmark. The plant serves a population of 3,602 residents and has a designed capacity of 3,500 cubic meters per day, with an actual discharge volume of 860.21 cubic meters per day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. As a Danish facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for discharges into sensitive areas. The plant's advanced treatment level aligns with Denmark's commitment to protecting the Baltic Sea from eutrophication. The treated effluent is discharged into the local coastal waters of the Baltic Sea, as the plant is within 10 km of the coast. The receiving water body is part of the Baltic Sea catchment, an ecologically sensitive semi-enclosed sea that faces challenges from nutrient pollution. The plant's advanced treatment helps reduce nitrogen and phosphorus loads, supporting the health of the marine environment.

The plant discharges into the Baltic Sea, a semi-enclosed sea with limited water exchange, making it vulnerable to nutrient enrichment. The surrounding watershed includes agricultural and urban areas on the island of Ærø. The Baltic Sea supports diverse aquatic life, including fish, seals, and migratory birds, and is an important ecological and economic resource for the region.
