Abstract

A method for treating an aqueous outgoing fluid carrying a coating composition from a coating bath, characterized by the steps of: mixing the outgoing fluid with a solution of higher composition content than the outgoing fluid; and treating the resulting mixture by a pressure-aided membrane separation process to reduce the water content and thereby provide a composition-enriched solution having a composition content at least equal to that used in the installation.
