Le filtre à pont mobile Hardinge :
Cette technologie innovante, brevetée en 1909, a constitué une avancée significative dans la filtration de l'eau. Elle comportait un pont qui se déplaçait le long d'un réservoir de filtration, permettant un rétrolavage continu et un nettoyage du filtre. Ce processus efficace a éliminé la nécessité d'arrêter l'ensemble du système de filtration, assurant un approvisionnement constant en eau propre. Le filtre à pont mobile Hardinge a été largement utilisé dans les stations de traitement des eaux municipales, les applications industrielles et même la filtration des piscines.
Acquisition et héritage :
En 1988, la gamme de produits de traitement de l'eau de Hardinge a été acquise par Infilco Degremont, Inc. Cette acquisition a consolidé la position d'Infilco Degremont en tant que leader mondial du traitement de l'eau, héritant de l'héritage d'innovation et de qualité de Hardinge.
L'héritage Hardinge continue d'impacter l'industrie aujourd'hui :
- Technologie fiable : Les filtres à pont mobile Hardinge sont connus pour leur conception robuste et leurs performances durables, même après des décennies de fonctionnement.
- Fonctionnement efficace : Le processus de rétrolavage continu garantit une efficacité de filtration élevée et un temps d'arrêt minimal.
- Flexibilité : La conception permet une personnalisation, s'adaptant à des débits variables et aux exigences de qualité de l'eau.
Bien que Hardinge n'existe plus en tant qu'entité indépendante, sa technologie innovante perdure à travers Infilco Degremont. Le filtre à pont mobile témoigne de sa contribution au traitement de l'eau et de son engagement à fournir des solutions fiables et efficaces pour une eau propre.
