Nogersunds avloppsreningsverk - Advanced Wastewater Treatment in Nogersund, Sweden

Nogersunds avloppsreningsverk is a municipal wastewater treatment plant located in Nogersund, a coastal locality in Sölvesborg Municipality, Blekinge County, Sweden. The plant serves a population of approximately 3,280 people, classifying it as a small agglomeration under Swedish and EU regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 6,000 m³/day and an average discharge volume of 514.90 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variability. The treated effluent is discharged into the Baltic Sea, as the plant is located within 10 km of the coast. The Baltic Sea is a sensitive marine environment with limited water exchange, making advanced treatment crucial for reducing nutrient loads and preventing eutrophication. The plant's location in the Blekinge archipelago underscores its role in protecting coastal water quality and marine ecosystems.

Nogersunds avloppsreningsverk discharges treated wastewater into the Baltic Sea, a semi-enclosed brackish sea with limited water exchange and high sensitivity to nutrient pollution. The plant's coastal location in the Blekinge archipelago means its effluent directly influences local marine habitats, including seagrass beds and fish spawning grounds. Advanced treatment helps reduce nitrogen and phosphorus loads, mitigating eutrophication risks in this ecologically important water body.
