In this research electrochemical treatment was used to treat Al-Sin water that feed Banias thermal station boilers for generate electricity , this recycled pure water minimize corrosion and wear of turbine, the current of (2A) and (12V) was applied by Transformer on metal electrodes of aluminum. The electrochemical treatment efficiency was studied. Results revealed that the turbidity decreased for about (98%), and that total dissolved solids (TDS) and conductivity were reduced by about (61%) and (70.8%) respectively after one hour of treatment process.
