Petfurdo Szennyviztisztito Telep Nitrogenmuvek Zrt Szvtisztito telepe - Advanced Wastewater Treatment in Pétfürdő

Petfurdo Szennyviztisztito Telep Nitrogenmuvek Zrt Szvtisztito telepe is an advanced wastewater treatment facility located in Pétfürdő, within the Közép-Dunántúl region of Hungary. The plant serves a population of 5,300 and has a designed capacity of 5,000 m³/day, with a current discharge volume of 624.77 m³/day. It is situated inland, more than 10 km from the coast, but within 50 km of the Adriatic Sea. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size (5,300 population equivalent) are required to provide secondary treatment, but the plant's advanced level indicates compliance with stricter standards, likely due to the sensitivity of the receiving environment. The plant is operated as part of the municipal wastewater infrastructure for Pétfürdő and the surrounding area. The treated effluent is discharged into local watercourses that ultimately drain into the Danube River basin, which flows into the Black Sea. The plant plays a key role in protecting the water quality of the region's rivers and groundwater, supporting aquatic ecosystems and downstream communities. Its advanced treatment helps reduce nutrient loading, which is critical for preventing eutrophication in the Danube and Black Sea.

The plant discharges into the local watershed within the Danube River basin, which flows through Central and Eastern Europe before reaching the Black Sea. The region's aquatic ecosystems support diverse fish and invertebrate populations, and the advanced treatment helps minimize nutrient pollution that could otherwise contribute to algal blooms and oxygen depletion in downstream waters. The plant's inland location reduces direct marine impact, but its effluent still influences the broader riverine environment.
