| Title of Invention | DEVICE AND METHOD FOR REGENERATING AN ELECTROLESS METAL PLATING BATH |
|---|---|
| Abstract | A device for regenerating an electroless metal plating bath, comprising a) electrodialysis arrangements (El, E2), each having diluate compartments (Dily, Di2y) for holding the metal plating bath, concentrate compartments (Koly, Ko2y) that are separated from the diluate compartments (Dily, Di2y) through ion exchange membranes and are intented to hold a concentrate fluid serving to adsorb interfering substances that are to be removed from the metal plating bath as well as anodes (An) and cathodes (Ka), and b) main cation exchangers (lx) for removing metal ions from the concentrate fluid, said cation exchangers being coupled to the concentrate compartments (Koly, Ko2y) in such a manner that the concentrate fluid is allowed to be conducted through the main cation exchangers (lx) and to be recirculated back into the concentrate compartments (Koly, Ko2y) by allowing the fluid to be circulated in a first circuit between the concentrate compartments (Koly, Ko2y) and collecting tanks (Vk) and in a second circuit between the collecting tanks (Vk) and the main cation exchangers (lx). |
