Abstract

Water treatment methods, as part of the peripheral units of a novel electrochemical machining device, were investigated with the aim of preparing the electrolyte, which was contaminated with heavy metal ions after machining of copper work pieces, for refeeding back to the system. Electrochemical machining (ECM) depends on machining the surface of a metal piece by ionization and removal of metal ions from the work area via the electrolyte. Removal of heavy metal ions in industrial waters and treatment of these waters for reuse is crucial in terms of increasing system efficiency and protecting environmental health. In this study, the ion exchange method was selected and a three-step application is proposed for the treatment of the electrolyte contaminated with copper ions after ECM. As the ion-exchanger, a paper filter was used in the first step, a natural zeolite with wide reserves in Turkey was used in the second step, and a polymer based cation exchange Lewatit TP 207 resin was used in the final step. Purification of the electrolyte, contaminated with copper ions, was achieved at 40 % as a result of treatment with the zeolite for two hours, at 90 % as a result of filtering three times using the paper filters, and at 100 % after treatment with the Lewatit TP 207 resin.
