Industrial desulfurization plant SO₂ series

The newly developed SO2 membrane system uses a purely physical process to remove SO2 from sweet reserve and young wines, thereby closing a major gap in enology. Procedure: Separated by a hydrophobic membrane, the SO2 diffuses from the sweet reserve or young wine into an alkaline rinsing solution. The transferred SO2 is irreversibly bound as a salt of the sulfurous acid and thus obtains the concentration gradient. During the SO2 reduction of young wine, slightly alkalized young wine is used as a rinsing solution. This means that there is no concentration gradient for all other ingredients of the young wine so they are not changed in the treated young wine. If the SO2 is to be removed from a sweet reserve, an alkaline rinsing solution on the other side of the membrane is sufficient..
