Fjallbo avloppsreningsverk - Advanced Wastewater Treatment in Hällefors, Sweden

Fjallbo avloppsreningsverk is a municipal wastewater treatment facility located in Hällefors, Örebro County, Sweden. The plant serves a population of approximately 3,506 residents and is designed to handle a capacity of 25,000 m³ per day. It provides advanced treatment, ensuring high-quality effluent before discharge. As an advanced treatment plant, Fjallbo avloppsreningsverk meets the stringent requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates tertiary treatment for sensitive areas and agglomerations over 10,000 population equivalent. Although the plant serves a smaller community, its advanced treatment level reflects Sweden's commitment to environmental protection and water quality. The treated wastewater is discharged into the local watershed, which ultimately drains into the Baltic Sea via the Norrström drainage basin. The plant plays a crucial role in protecting downstream aquatic ecosystems, including rivers and lakes in the region, by removing nutrients and pollutants that could cause eutrophication and harm biodiversity.

The plant discharges into the local water system, which flows through the Norrström basin and eventually reaches the Baltic Sea. The Baltic Sea is a brackish water body sensitive to nutrient pollution, making advanced treatment essential to prevent algal blooms and maintain ecological balance. The surrounding region includes forests and lakes that support diverse aquatic life, and the plant's operations help preserve water quality for both human use and wildlife.
