Was Brunnen jung hält

Berliner Forscher haben das Phänomen der Brunnenalterung untersucht

(PresseBox) (Berlin, )
Wenn im Grundwasser Eisenbakterien und Sauerstoff in einem bestimmten Verhältnis zueinander stehen, dann altern Brunnen schnell. Das ist das Kernergebnis des Forschungsprojektes WELLMA.

Auch Trinkwasserbrunnen werden älter. Dies erkennen Fachleute vor allem daran, dass die geförderte Wassermenge aus einem Brunnen kontinuierlich sinkt, obwohl die Wasserpumpen mit gleicher Kraft arbeiten. Für Berlin mit insgesamt rund 650 Trinkwasserbrunnen bedeutet dies einen erheblichen Aufwand an Energie sowie technischen und personellen Ressourcen.

Der wohl problematischste Prozess der schleichenden Brunnenalterung ist die Verockerung: die im Grundwasser stehenden Brunnen-Filterrohre wachsen langsam mit eisenhaltigen Biofilmen zu. Gegen diesen immer wieder nachwachsenden Belag müssen Brunnenbetreiber mit aufwändigen Reinigungsmaßnahmen jwchqjli. Bkf obl mgqmqxex- cal mxbgconsnqgsuo.
