Abstract

In this research electrochemical treatment was used to treat Al-Sin water that feed Banias thermal station boilers for generate electricity. The effect of the operating parameters such as type of electrodes, initial pH,inter electrode distance, electrolysis time and current density on the effectiveness of electrochemical processing were studied in reducing the concentration of total dissolved solids (TDS), NaCl concentration, and electrical conductivity. The experiments were carried out in a batch mode. Results revealed that in the optimum conditions (current density=500A/m², distance between electrodes =10mm) the total dissolved solids, conductivity, and NaCl concentration were reduced by (97%), (94%) and (92%) respectively after one hour of treatment process by using aluminum electrodes.
