The present invention relates to a method for separating mixtures of substances using a material which is pervious to said substances. The use of this material for separating substances comprises briefly applying a voltage on the material, which substantially increases the efficiency of substance separation methods such micro-filtration or ultra-filtration. The material used as a membrane can be purified in different ways by applying a voltage thereto, the separation capacity being thus increased while providing an even cleaning of the membrane. The material used as a membrane can also be heated by applying a voltage thereto so as to increase the transfer of matter through the membrane. This method can be used for separating substances in various gas or liquid mixtures as well as in solutions.
L'invention concerne un procédé pour la séparation de mélanges de substances au moyen d'un matériau perméable à ces substances. L'utilisation de ce matériau pour la séparation des substances par brève application d'une tension sur le matériau permet d'accroître notablement l'efficacité de procédés de séparation de substances, comme par exemple la microfiltration ou l'ultrafiltration. D'une part, le matériau faisant office de membrane peut être purifié de différentes manières par application d'une tension, le pouvoir séparateur s'en trouvant accru avec un nettoyage régulier de la membrane, et d'autre part le matériau utilisé comme membrane peut être chauffé par application d'une tension, ce qui permet d'augmenter le transport de matière à travers la membrane. Ce procédé peut s'utiliser pour la séparation de substances dans divers mélanges de gaz, mélanges de liquides ou solutions.
