Bohus Malmons avloppsreningsverk - Advanced Wastewater Treatment in Kullebacken, Sweden

Bohus Malmons avloppsreningsverk is a wastewater treatment facility serving the Kullebacken area in Sotenäs municipality, Västra Götaland County, Sweden. The plant is situated along the west coast, reflecting the region's coastal geography and its importance for marine environmental protection. The plant operates with advanced treatment processes, meeting stringent Swedish and EU standards for wastewater treatment. With a designed capacity of 2800 cubic meters per day, it is sized to handle the local population and seasonal variations. Under the EU Urban Waste Water Treatment Directive, advanced treatment is required for sensitive areas, which coastal zones often are, to reduce nutrient loads and protect the marine environment. The treated effluent is discharged into the coastal waters of the Skagerrak, part of the North Sea. This area supports diverse marine life and is important for fisheries and tourism. The advanced treatment helps minimize eutrophication risks and maintains water quality in the surrounding coastal ecosystem.

The plant discharges into the Skagerrak, a strait connecting the North Sea to the Kattegat and Baltic Sea. This coastal region is ecologically sensitive, supporting diverse marine habitats including kelp forests and fish spawning grounds. Advanced treatment reduces nutrient and pollutant loads, protecting the marine environment from eutrophication and safeguarding local biodiversity.
