Berlin's blower benefits

摘要

Since the fall of the Wall in 1989, Berlin has seen continuous development with the reunification of East and West Germany, and Berlin's resumption of its role as capital. One of the city's most radical environmental projects was to reestablish a nature reserve around parts of the Rummelsburger See, a 3km~2 (740 acres) lake, as well as the rebuilding of the residential area. Luxury apartments have been built and more are under construction around the once thriving harbour side. To attract residents the Berlin Senate knew that it would need to solve a major problem; the Rummelsburger See was stagnant. Years of use as a harbour and the lack of oxygenated water flowing through it had resulted in a lake empty of any wildlife and discoloured due to the huge amounts of algae that had formed. AGO HydroAir GmbH was contracted to solve this problem but knew that the answer would not be straightforward.
