DALMOSE Wastewater Treatment Plant, Dalmose, Denmark

DALMOSE is a wastewater treatment plant located in Dalmose, Slagelse Municipality, Region Sjælland, Denmark. The facility serves a population of approximately 1,412 and is part of the municipal wastewater infrastructure for the local community. The plant employs advanced treatment processes, ensuring high-quality effluent before discharge. With a designed capacity of 3,000 m³/day and an average daily flow of 541 m³/day, the plant operates well within its capacity. As a Danish facility, 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 the local watershed, which ultimately drains into the Baltic Sea. The plant plays a key role in protecting downstream water bodies from nutrient pollution, supporting the ecological health of the region's coastal and marine environments.

The plant discharges into the local catchment that feeds into the Baltic Sea via the Great Belt. The Baltic Sea is a semi-enclosed brackish sea sensitive to nutrient enrichment, making advanced treatment crucial for reducing eutrophication risks. The surrounding area includes agricultural land and small watercourses that support diverse aquatic life.
