Does reverse osmosis filter out PFAS?
1 answer
Les PFAS, en raison de leur structure chimique et de leur taille, sont efficacement rejetés par la membrane d'osmose inverse, bien que l'efficacité puisse varier en fonction de la configuration du système et des conditions opérationnelles. Des études techniques démontrent des taux de rejet dépassant souvent 90 % pour les PFAS.
Cependant, pour une performance optimale, il est crucial d'assurer un entretien régulier du système, notamment le remplacement périodique de la membrane, pour éviter le colmatage et maintenir un taux de rejet élevé. Le système doit également être couplé à un prétraitement adéquat pour éliminer les particules en suspension et les autres contaminants qui pourraient endommager la membrane.
