Filtre à Pont Mobile (FPM) : Un Pont vers l'Eau Propre
Le Filtre à Pont Mobile (FPM), un élément vital du traitement de l'eau, est une merveille d'ingénierie qui allie parfaitement efficacité et efficience. Il est particulièrement précieux pour traiter de grands volumes d'eau, ce qui en fait un acteur essentiel dans les applications municipales, industrielles et agricoles.
Fonctionnement :
Le FPM est essentiellement un système de filtration mobile et autonome. Il comprend une série de modules de filtration parallèles, généralement en sable ou en anthracite, montés sur une structure en forme de pont qui se déplace le long d'une voie dédiée. Lorsque le pont se déplace, l'eau est continuellement filtrée à travers les modules, éliminant les solides en suspension et autres impuretés. Le principal avantage de ce système réside dans son fonctionnement continu. Pendant qu'un ensemble de modules filtre l'eau, l'autre ensemble subit un contrelavage, où le lit filtrant est nettoyé et préparé pour le cycle suivant. Cela garantit un traitement de l'eau ininterrompu et une qualité de sortie constante.
Avantages de l'utilisation d'un FPM :
- Débits élevés : Les FPM sont conçus pour gérer des volumes d'eau importants, ce qui les rend idéaux pour les opérations à grande échelle.
