Frondenberg Fromern Wastewater Treatment Plant, Fröndenberg/Ruhr, Germany

Frondenberg Fromern is an advanced wastewater treatment plant located in Fröndenberg/Ruhr, in the district of Unna, Nordrhein-Westfalen, Germany. The plant serves a population of approximately 2,100 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant provides advanced treatment, which goes beyond the secondary treatment standard required by the EU UWWTD for agglomerations of this size. With a designed capacity of 2,000 m³/day and an average discharge volume of 531.46 m³/day, the plant operates well below its capacity, indicating room for future growth or efficient water management. The treated effluent is discharged into the local water system, which ultimately drains into the Ruhr River. The Ruhr River flows through the densely populated and industrialized Ruhr region before joining the Rhine River, which then empties into the North Sea. The plant's advanced treatment helps protect the Ruhr's water quality and downstream ecosystems.

The plant discharges into the Ruhr River, a major tributary of the Rhine River, which flows through the Ruhr region and eventually reaches the North Sea. The Ruhr River supports diverse aquatic life and is used for drinking water supply, making advanced treatment crucial for maintaining water quality. The plant's location in an inland, industrialized area means its effluent must meet strict standards to prevent nutrient pollution and protect downstream habitats.
