Abstract

A procedure for treating a coating composition incorporated in water from a coating facility in which articles are coated in a bath containing said coating composition and are then transferred to a separate washing station where it is removed by washing the excess composition of the articles, characterized by the improvement that comprises removing the composition from the bath, treating the removed composition by means of a pressure membrane separation procedure to vary the concentration of water or water-soluble components of the composition and return the treated composition to the bathroom.
