The Phoenix Lake in Dortmund is an artifical lake in a former steel production area. GEH 104 is used to constantly remove phosphate from the lake water. In this way, the phosphate concentration is kept below a critical value to prohibit excessive algae growth and the eutrophication of the lake.
The total lake volume of 600,000 m3 is treated over one year by three adsorbers in parallel.
