Overview
NORDOSTANLAEGGET is a wastewater treatment plant in Odense, Denmark, serving approximately 21,306 people. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
NORDOSTANLAEGGET is a wastewater treatment plant located in Odense, Denmark, serving a population of approximately 21,306. Situated in the Odense Kommune, the plant is part of the municipal wastewater infrastructure for the city of Odense, a major urban center on the island of Funen. The plant's location near the coast places it within the regulatory framework for sensitive areas under Danish and EU law. As a medium-sized agglomeration, NORDOSTANLAEGGET is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges to freshwater and estuaries, and more advanced treatment for discharges to sensitive areas. The plant's designed capacity is 1.00 (likely in cubic meters per day or similar unit), indicating its scale. Danish wastewater treatment plants typically employ biological treatment processes to meet stringent nutrient removal standards, particularly for nitrogen and phosphorus, to protect the Baltic Sea from eutrophication. The plant's treated effluent is discharged into the Odense Fjord, which flows into the Kattegat and ultimately the Baltic Sea. This coastal discharge is ecologically significant as the Baltic Sea is a semi-enclosed sea with limited water exchange, making it highly sensitive to nutrient pollution. The plant's operation contributes to the protection of marine ecosystems and supports Denmark's commitments under the Helsinki Convention (HELCOM) to reduce nutrient inputs to the Baltic Sea.
Environmental context
NORDOSTANLAEGGET discharges treated wastewater into the Odense Fjord, which connects to the Kattegat and then the Baltic Sea. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it highly sensitive to nutrient enrichment. The plant's location within 50 km of the coast means its discharge can influence coastal water quality and marine ecosystems, including habitats for fish, birds, and benthic organisms. Effective nutrient removal is critical to prevent eutrophication and algal blooms in this vulnerable marine environment.
Frequently asked questions
NORDOSTANLAEGGET is located in Odense, Denmark, on the island of Funen. Its address is Havnegade, Skibhusene, Odense, Odense Kommune, 5240, Danmark.
The plant serves approximately 21,306 people, classifying it as a medium-sized agglomeration under EU regulations.
The plant discharges treated effluent into the Odense Fjord, which flows into the Kattegat and then the Baltic Sea. This coastal discharge is subject to strict nutrient removal requirements to protect the sensitive Baltic marine environment.
As a Danish plant, NORDOSTANLAEGGET operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations over 2,000 population equivalent and more advanced treatment for discharges to sensitive areas like the Baltic Sea.
Plants of this scale in Denmark typically employ biological treatment with nutrient removal (nitrogen and phosphorus) to meet stringent standards. This often includes activated sludge processes with denitrification and chemical phosphorus precipitation, in line with HELCOM recommendations for Baltic Sea protection.
