Verstopfte Brunnen - BGR-Forscher verbessern Reinigungsverfahren

Wasserversorgung

(PresseBox) (Hannover, )
Die Trinkwasserversorgung in Deutschland beruht zu ca. 80 % auf Grundwasser, das aus Brunnen gefördert wird. Häufig jedoch behindern Ablagerungen von Mineralen und Biomasse im Brunnenfilter den Wasserzutritt oder sorgen sogar für eine komplette Verstopfung des Brunnens. Wissenschaftler der BGR haben jetzt gemeinsam mit Unternehmen der Trinkwasserversorgung bei Forschungsarbeiten Ansatzpunkte für eine zielgerichtete Bekämpfung des Problems gefunden.

"Häufigste Ursache der Brunnenalterung - vor allem in Norddeutschland - ist die sogenannte "Verockerung", d.h. die Ablagerung von festen Oxiden des Eisens", erklärt Dr. Georg Houben, Leiter des BGR-Arbeitsbereichs Grundwasserbeschaffenheit und -schutz. Die Oxide bilden sich bei der Mischung von tiefen, eisenhaltigen Grundwässern psb ywivqswnqhgzskwu, mwiwiocyiulrlkmhk Fasxls.
