ORUM Wastewater Treatment Plant, Ørum, Denmark | Advanced Treatment Facility

ORUM is a wastewater treatment plant located in Ørum, a town in the Region Midtjylland of Denmark. The plant serves a population of approximately 1,423 people, reflecting its role in managing municipal wastewater for this small community. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 4,000 m³/day and an actual discharge volume of 352.83 m³/day, the facility operates well within its capacity. As a Danish plant, it complies with the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for sensitive areas. The treated effluent is discharged into local watercourses that drain into the Limfjord or the North Sea. The plant's advanced treatment helps protect downstream aquatic ecosystems, including the nutrient-sensitive waters of the Limfjord, which support diverse marine life and are important for fisheries and recreation.

The plant's discharge enters local streams that flow into the Limfjord, a shallow sound connecting the North Sea and the Kattegat. The Limfjord is an ecologically sensitive area supporting diverse fish, bird, and plant species. Advanced treatment at ORUM reduces nutrient loading, helping to prevent eutrophication and maintain water quality in this important coastal ecosystem.
