Better treatment of urban wastewaters improves the state of the Baltic Sea


Eutrophication is a major problem in the Baltic Sea. It is caused by excessive nutrient loads entering the sea from land. Reduction of especially phosphorus loads is urgently needed in order to improve the state of the sea.

PURE implements one of the most cost-effective ways to reduce the eutrophication of the Baltic Sea: it enhances phosphorus removal at municipal wastewater treatment plants. The project partners aim to achieve an average annual concentration of 0.5 mg phosphorus / litre in outgoing wastewaters. This is the level recommended by the HELCOM Baltic Sea Action Plan.
PURE also maps, develops and shares good practices and innovative techniques on handling and recycling wastewater sludge.
