Abstract

L'invention concerne un procédé destiné à purifier l'eau des contaminants et à fabriquer de l'eau à faible teneur en substances dissoutes telles que le sel dans l'eau de mer. Le procédé, qui consiste à faire passer l'eau à travers une membrane à zéolites qui a été traitée avec de l'acide silicique ou avec un silicate d'alkyle, permet d'obtenir un flux d'eau très important à très faible teneur en contaminants.
