METHOD FOR SEPARATING MIXTURES OF SUBSTANCES USING A MATERIAL PERVIOUS TO SAID SUBSTANCES

摘要

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.
