Comprendre les caractéristiques, les applications et les exigences de nettoyage de la membrane de microfiltration

Il existe de nombreux types de membranes utilisées dans le traitement de l'eau, et les membranes de microfiltration sont également largement utilisées. Ces membranes peuvent intercepter des particules allant de 0.1 à 1 micron. Les membranes de microfiltration peuvent permettre aux grosses molécules et aux solides dissous de passer en douceur, mais peuvent retenir les solides en suspension et un grand nombre de bactéries. Généralement, la pression de fonctionnement est comprise entre 0.3 et 7 bar. On peut dire que la filtration par membrane de microfiltration est l'une des premières technologies membranaires développées et appliquées au monde, utilisant principalement des matériaux membranaires naturels et synthétisés artificiellement. Dans le même temps, le mécanisme de séparation des membranes de microfiltration est principalement le criblage et le piégeage.

Comprendre les membranes de microfiltration

Les membranes de microfiltration sont divisées en membranes inorganiques et membranes polymères organiques en fonction de leurs matériaux filmogènes. Les membranes inorganiques sont divisées en membranes céramiques et membranes métalliques, et les membranes polymères organiques sont divisées en membranes polymères naturelles et membranes polymères synthétiques. Selon la forme de la membrane, elle peut être divisée en membrane plate, membrane tubulaire, membrane laminée et membrane de fibre creuse. Selon le principe de préparation de la membrane, les méthodes de préparation des membranes polymères comprennent la méthode de lixiviation (méthode sèche-humide), la méthode de trou d'étirement, la méthode de transformation de phase, la méthode induite thermiquement, la méthode de revêtement par immersion, méthode d'irradiation, méthode de modification chimique de surface, méthode de voie nucléaire, méthode de formation dynamique, Etc. En tant que principal fournisseur de membrane en céramique en Chine, Jiawu High-Tech s'est toujours concentré sur la recherche et le développement de la technologie avancée de membrane en céramique.

Caractéristiques et applications des membranes de microfiltration

L'efficacité de séparation peut atteindre un bon niveau, mais cela dépend également de la taille des pores et de la distribution de la taille des pores de la membrane. Pour toutes les membranes de microfiltration, la taille des pores doit être la même et la précision doit être élevée, ce qui a une bonne fiabilité.
La porosité de surface de la membrane de microfiltration est élevée, atteignant généralement 70%, ce qui est jusqu'à quarante fois plus élevé que la capacité de filtrage des membranes ordinaires.
L'épaisseur de la membrane de microfiltration est mince, donc elle ne causera pas trop de perte.
Un grand nombre de membranes de microfiltration à haut polymère sont connectées en série, ce qui ne provoquera pas de pollution secondaire. Les membranes de microfiltration sont appliquées dans la filtration et la stérilisation de l'industrie pharmaceutique, de l'industrie alimentaire, de l'industrie de la peinture et de l'industrie de la biotechnologie.

Exigences pour le nettoyage des membranes de microfiltration

Placez toutes les membranes à plat dans le dispositif de nettoyage, faites-les tremper dans l'eau à environ 70 ℃ et mouillez-les complètement. Après plus de quatre heures, filtrez toute l'eau et faites-les tremper dans une quantité appropriée d'eau distillée chaude pour le nettoyage.
La membrane de microfiltration doit être complètement installée dans le dispositif de nettoyage pour éviter d'être affectée par d'autres liquides et atteindre un certain état de filtration.
