KLOVERHAGE RENSEANLAEG - Advanced Wastewater Treatment in Kongshøj, Denmark

KLOVERHAGE RENSEANLAEG is an advanced wastewater treatment plant located in Kongshøj, a locality in Nyborg Municipality, Region of Southern Denmark. The plant serves a population of 734 and has a designed capacity of 5,000 m³/day, with an actual discharge volume of 747.43 m³/day. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for Danish plants in sensitive coastal areas. Denmark implements the EU Urban Waste Water Treatment Directive (91/271/EEC), requiring advanced treatment for discharges into sensitive areas like the Baltic Sea. The plant's treated effluent likely discharges into the Great Belt (Storebælt), a major strait connecting the Baltic Sea to the Kattegat. This coastal discharge contributes to the nutrient load in the Baltic Sea, a semi-enclosed sea sensitive to eutrophication. Advanced treatment helps mitigate algal blooms and supports marine ecosystem health.

The plant discharges into the Great Belt (Storebælt), which connects the Baltic Sea to the Kattegat and ultimately the North Sea. The Baltic Sea is a brackish, semi-enclosed sea highly sensitive to nutrient pollution, leading to eutrophication and dead zones. Advanced treatment at this plant helps reduce nitrogen and phosphorus inputs, protecting coastal habitats and supporting biodiversity in the region.
