The world´s largest Calcium filter bed installed at Svensksund, Norrköping

The construction and installation of the world´s largest Calcium filter bed was completed in december 2020, at Svensksund east of Norrköping, Sweden. The filter bed contains almost 1000 m3 of Calcium material. It will reduce the transport of Phosphorus in the stream Vadsbäcken to the Baltic Sea bay Bråviken significantly. The measure will also contribute to preserve a large RAMSAR wetland at the outlet of Vadsbäcken.
