Exploiter le pouvoir des tornades : Aération de surface par aspiration pour le traitement de l'eau et de l'environnement

Le terme "tornade" peut évoquer des images d'événements météorologiques destructeurs, mais dans le monde du traitement de l'eau et de l'environnement, il prend un sens très différent. Ici, "tornade" fait référence à un type de technologie d'aération de surface puissante et efficace.

L'aération de surface joue un rôle crucial dans l'amélioration de la qualité de l'eau en augmentant les niveaux d'oxygène dissous (OD). Ceci est essentiel pour divers processus, notamment :

  • Traitement des eaux usées : Des niveaux d'OD adéquats sont essentiels pour la dégradation de la matière organique par les bactéries aérobies, garantissant un traitement efficace des eaux usées.
  • Aquaculture : Un OD suffisant est essentiel pour la santé et la survie des organismes aquatiques dans les fermes piscicoles et autres environnements d'aquaculture.
