The modern desalination process for saving water is membrane capacitive deionization in which voltage is applied between two opposite-charged carbon electrodes. An ion exchange membrane is set beside each electrode, and a spacer is placed between them to carry the treated water. The current study shows water conservation along with the reduction in chemical treatment costs in cooling towers with seawater in circulation. Chemical savings of approximately 80 % might be achieved by monitoring the cooling tower's water usage and comparing it to a situation without MCDI. Furthermore, 24% water reductions, as well as 44% saving in terms of wastewater, are possible. MCDI in range 0.15& 0.25 kWh/m3 of generated LSW for cooling tower inlet water. Due to the absorption of calcium and chloride ions, the chances of scaling and corrosion decrease significantly which helps in water and chemical savings.
