Özet

In this study, separation performance for monovalent salts (NaCl, KCl) and divalent salts (CaCl2 MgCl2) was investigated by electrodialysis at pH 6.0-6.5, 4.0 and 2.0 using constant voltage mode of operation. TS-1-10 electrodialysis equipment (Tokuyama) modified with rotameters was employed in "experimental studies. The effect of electrical potential, pH and ion valency on separation performance was studied at room temperature using a constant flow rate. The efficiencies of each run were evaluated as specific power consumption with the electrical energy consumed only in stack.
