Growth of population, increasing urbanization and industrialization, and the rather limited natural resources of potable water leading to serious deficits of freshwater in many regions in the world specially in middle east and golf area. Current water desalination techniques are energy intensive leading to inhibit the wide use of current sea desalination techniques. In this research a lab scale pilot was introduced using a special electrolysis circuit and vibrator producing a square wave powered by solar energy to decrease 35 % of the total dissolved salts/hour in sea water samples.
