Agidisc : Révolutionner la séparation solide-liquide dans les applications environnementales

L'Agidisc, un filtre à disques breveté avec système d'agitation intégré développé par Baker Process, est un véritable révolutionnaire dans le domaine de la séparation solide-liquide, en particulier pour les applications environnementales. Cette technologie innovante combine l'efficacité des filtres à disques traditionnels avec un système d'agitation unique, offrant une solution puissante pour un large éventail de défis.

L'avantage Agidisc :

L'innovation principale de l'Agidisc réside dans son **système d'agitation intégré**, qui s'attaque à un problème crucial rencontré par les filtres à disques classiques : l'accumulation et le colmatage du gâteau. Les filtres à disques traditionnels comptent sur la gravité pour drainer le liquide, ce qui conduit à la formation de gâteaux sur la surface du filtre. Cela peut entraîner une réduction des débits de filtration, une augmentation des pertes de charge et, en fin de compte, un fonctionnement inefficace.

L'Agidisc s'attaque à ce problème de front en intégrant un **bras d'agitation rotatif** dans la chambre du filtre. Ce bras, stratégiquement positionné au sein du gâteau, remue doucement les solides, empêchant l'accumulation du gâteau et garantissant une filtration continue et efficace.

Avantages de l'utilisation d'Agidisc dans les applications environnementales :

La conception unique de l'Agidisc offre une multitude d'avantages pour les applications environnementales, notamment :

  • Séparation solide-liquide améliorée : Le système d'agitation assure une séparation plus complète des solides des liquides, ce qui donne un effluent plus propre et plus concentré.
  • Réduction des temps d'arrêt : Les performances de filtration constantes minimisent le besoin de nettoyages fréquents du filtre, réduisant les temps d'arrêt opérationnels et augmentant l'efficacité du processus.
  • Efficacité énergétique accrue : La conception optimisée et le colmatage réduit de l'Agidisc conduisent à une consommation d'énergie inférieure, minimisant l'impact environnemental du processus de filtration.
  • Traitement des solides difficiles : Le système d'agitation est particulièrement efficace pour le traitement des solides visqueux ou collants, qui posent des défis aux filtres traditionnels.
  • Polyvalence : L'Agidisc convient à un large éventail d'applications, y compris le traitement des eaux usées, la déshydratation des boues, la clarification des eaux de process industrielles, et plus encore.

Applications spécifiques :

La polyvalence de l'Agidisc s'étend à de nombreuses applications environnementales, telles que :

  • Traitement des eaux usées municipales : Éliminer efficacement les solides en suspension des eaux usées, améliorant la qualité de l'eau pour le rejet ou la réutilisation.
  • Traitement des eaux usées industrielles : Filtrer et traiter les flux d'eaux usées industrielles, en respectant les réglementations environnementales et en réduisant les volumes de rejet.
  • Déshydratation des boues : Déshydrater efficacement les boues des stations d'épuration des eaux usées, réduisant les coûts de traitement et maximisant la récupération des ressources.
  • Séparation pétrole et gaz : Séparer l'eau de la production pétrolière et gazière, améliorant la qualité du pétrole et minimisant l'impact environnemental.
