ubular electrodialysis cells for electrophoresis (anaphoresis and cataphoresis) plants were first used in Italy in December 1993, with the first important industrial installation (Fig. 1) carried out by Verind, a company belonging to the Dürr A.G. Group that has been operating in the surface finishing, fluid handling, ultrafiltration, and water treatment markets for sixty years. In the following years, there was a growing interest in this type of cells thanks to their ease of installation, higher yields per square metre of

painted surface, better penetration in generally difficult-to-reach areas, and higher homogeneity of the deposited coated film. The ediVer cell (Fig. 2) now supplied and installed by Verind is the result of a technical evolution that has led to the development of a product enabling to replace only the worn membrane film without having to change the whole structure. The experience gained with more than 5,000 cells installed in at least 300 plants since 1993 enables Verind to provide the users with innovative
