    摘要: The invention relates to a process for separating electrically charged solid particles or macromolecules contained in a solution by using a semi-permeable membrane which is specific for the separation to be carried out and by applying an electric field to reduce the concentration gradient in the immediate vicinity of the membrane. In the present invention, a plurality of semi-permeable membranes (2, 3) are arranged directly oppositely each other so as to define an alternation of low and high pressure compartments (4, 5), and periodically the direction of the electric field is reversed. The process of the invention allows increasing the exchange area while benefiting of permanently increased efficiency from the applied electric field.
