Que sont les polymères Acumer ?
Les polymères Acumer sont essentiellement de longues chaînes de molécules conçues pour interagir avec l'eau et diverses impuretés présentes dans celle-ci. Ces interactions, basées sur des principes chimiques et physiques, permettent aux polymères Acumer d'exécuter une série de fonctions, notamment :
- Coagulation et floculation : Les polymères Acumer aident à éliminer les solides en suspension de l'eau en rassemblant de petites particules en amas plus importants et plus faciles à éliminer (coagulation), puis en agrégeant davantage ces amas (floculation). Ce processus est essentiel dans la purification de l'eau pour l'eau potable, le traitement des eaux usées et les applications industrielles.
- Inhibition de l'entartrage : L'eau dure contient des minéraux dissous comme le calcium et le magnésium, qui peuvent former des dépôts d'entartrage sur les tuyaux et les équipements, gênant le flux et l'efficacité. Les polymères Acumer peuvent inhiber la formation d'entartrage, empêchant ainsi une maintenance coûteuse et des temps d'arrêt.
- Filtration : Les polymères Acumer améliorent l'efficacité des processus de filtration en agissant comme des adjuvants de filtration, améliorant l'élimination des solides en suspension et autres impuretés.
- Déshydratation : Les polymères Acumer peuvent être utilisés pour éliminer l'eau de divers matériaux, facilitant les processus de séchage et améliorant la qualité du produit.
Pourquoi choisir les polymères Acumer ?
Plusieurs facteurs font des polymères Acumer un choix populaire pour les applications de traitement de l'eau :
