Abstract

See full text

The invention relates to a method and system for processing a solution. In at least one first membrane unit (3), a feed flow (2) is separated into a permeate flow (5) and a retentate flow (6). According to the invention, at least part of the retentate flow (6) is fed to at least one second membrane unit (7). In the second membrane unit (7), retentate is located on one side of a membrane (8). Located on the other side is a solution (9), the concentration of dissolved substances of which is lower than that of the retentate. Thus solvent of the solution (9) passes through the membrane (8) and thins the retentate.
