Title
(DE) SCHAUMGLASFILTER
(EN) FOAMED GLASS FILTER
(FR) FILTRE EN VERRE CELLULAIRE
Abstract
(DE)
Es wird ein Leicht-Filter beschrieben, bei dem Schaumglas durch Polyurethan-Bindemittel gebunden wird. Auch ohne mechanische Verfestigung werden so Brunnenelemente für eine Tiefe von mindestens 80 m erhalten. Der Filter eignet sich besonders zur Gewinnung von Trinkwasser aus Grundwasser in Tagebaugebieten.
(EN)
The description relates to a lightweight filter in which foamed glass is bonded by polyurethane binders. This provides well units for a depth of at least 80 m even without mechanical compacting. The filter is especially suitable for obtaining drinking water from the water table in open-cast mining areas.
(FR)
L'invention décrit un filtre léger dans lequel du verre cellulaire est lié par des liants polyuréthanne. Même sans solidification mécanique, on obtient ainsi des éléments de puits pour une profondeur d'au moins 80 m. Le filtre est particulièrement adapté pour extraire de l'eau potable des eaux souterraines dans les régions de mines à ciel ouvert.
