Abstract
Membrane polymère pour la nanofiltration, ladite membrane contenant une couche de macrovides ayant un premier côté et un second côté, une première couche poreuse recouvrant le premier côté de la couche de macrovides, une seconde couche poreuse recouvrant le second côté de la couche de macrovides, et une couche en film mince recouvrant la première couche poreuse. La membrane de nanofiltration selon l'invention a une limite de diffusion en poids moléculaire de 100 à 5000 Dalton et une perméabilité à l'eau pure de 0,1 à 200 Lm-2bar-1h-1. Un procédé de préparation de ladite membrane et un procédé pour l'utiliser sont également décrits.
