Lake - Eichbaumsee
Eichbaumsee is a 24 hectare recreational lake in the Hamburg suburb of Bergedorf in Germany, which had been permanently closed for recreational use in the three years prior to the application due to poor water quality. Previous measures undertaken in order to to solve this problem, including an application of 115 tonnes aluminium sulphate, destratification and deep water aeration, were unsuccessful.
Bentophos GmbH, Phoslock Water Solutions' licensee for Germany, was commissioned by the BSU Hamburg ("Behörde für Stadtentwicklung und Umwelt") to treat the lake with Phoslock (sold in Germany under the tradename Bentophos). The treatment with 148 ton Phoslock took place in the second half of November 2010.
