Assessing the effect of electrode separation and voltage on the potential of calcium and magnesium ions removal during electrochemical water softening :

Abstract

There are various techniques for removal of water hardness each with its own special advantages and disadvantages. Electrochemical water softening method due to its simplicity has gained a great attention and is used for removal of various ions and other organic matters. The aim of this research work was to investigate the effect of electrode separation on the potential of calcium and magnesium ion removal during electrochemical water softening under different conditions. An electrolytic cell was prepared to remove these ions by electro precipitation. The cell consisted of 1 litre beaker, cathode and an anode. Both the cathode and the anode were made of stainless steel electrodes each of 15.5𝑐𝑚 length and a width of 5.5𝑐𝑚 The effect of different operating parameters was investigated and majorly electrode separation and voltage were evaluated.
