DynaSand : Une révolution dans le traitement de l'eau

La technologie DynaSand®, développée par Parkson Corporation, représente une avancée significative dans le domaine du traitement de l'eau. Elle utilise un filtre à sable à lit mobile à contre-lavage continu, offrant une approche unique de la filtration avec de nombreux avantages par rapport aux systèmes de filtration au sable traditionnels.

Comprendre DynaSand :

DynaSand® est essentiellement un filtre à sable autonettoyant qui fonctionne en continu. Le cœur du système réside dans son lit de sable mobile. Contrairement aux filtres classiques où le sable reste stationnaire, le système DynaSand® utilise un flux d'eau ascendant continu, suspendant les particules de sable et créant un « lit fluidisé ». Ce mouvement permet l'élimination efficace des contaminants et des débris, tout en assurant une performance de filtration constante.

Caractéristiques et avantages clés :

  • Contre-lavage continu : Le système élimine constamment les débris accumulés en effectuant un contre-lavage continu d'une partie du lit de sable. Cela garantit une performance de filtration optimale tout au long du processus, éliminant le besoin d'arrêts programmés pour le contre-lavage comme les filtres traditionnels.
  • Efficacité de filtration élevée : Le mouvement continu du sable crée un milieu de filtration dynamique, améliorant la capture et l'élimination des particules les plus fines. Cela conduit à une plus grande efficacité d'élimination des solides en suspension, de la turbidité et d'autres contaminants.
  • Coûts d'exploitation réduits : Le contre-lavage continu minimise la quantité d'eau utilisée pour le contre-lavage, ce qui permet des économies d'eau importantes. De plus, les temps de fonctionnement du filtre prolongés réduisent la fréquence de la maintenance du filtre, ce qui minimise les coûts de main-d'œuvre et les temps d'arrêt.
  • Applications polyvalentes : DynaSand® convient à une large gamme d'applications, notamment le traitement des eaux municipales, le traitement des eaux usées industrielles et la purification de l'eau potable. Sa capacité d'adaptation permet un traitement efficace de la qualité de l'eau et des niveaux de contaminants variables.
  • Maintenance réduite : La conception autonettoyante du système réduit le besoin de nettoyage et d'entretien manuels, ce qui entraîne des coûts opérationnels réduits et moins d'interruptions du processus de traitement de l'eau.

Le filtre à sable à lit mobile à contre-lavage continu de Parkson Corporation est un excellent exemple de la technologie DynaSand® en action. Le filtre offre des performances exceptionnelles avec un haut degré d'automatisation et une intervention opérationnelle minimale. Le système utilise un processus de contre-lavage unique qui combine la fluidisation et le contre-lavage pour éliminer efficacement les contaminants. Cette approche novatrice garantit des performances optimales tout en minimisant la consommation d'eau et les temps d'arrêt opérationnels.

Conclusion :

La technologie DynaSand® transforme l'industrie du traitement de l'eau. Le filtre à sable à lit mobile à contre-lavage continu offre plusieurs avantages par rapport aux méthodes traditionnelles, notamment une efficacité accrue, des coûts d'exploitation réduits et une fiabilité opérationnelle accrue.
