Water, an essential element for life, makes up 71% of the planet’s surface. Paradoxically, 3.5% of this water is suitable for human consumption and other use, to be found in lakes, rivers, and springs to supply our physical and hygienic needs. Only 1% is available for drinking. The remaining 97.5%, located in seas and oceans, is not drinkable due to its high level of salinity. Raw water goes through a special method by dosing lime, bleaching powder and ferrous sulfate for treated water. On the other hand, Reverse, Osmosis is a membrane-based method technology to purify water from oceans and no need extra chemical. Reverse Osmosis technology is employed to get rid of dissolved solids, color, organic contaminants, and nitrate from the feed stream. It is low costing, energy-efficient also produce blue current. There is 1 square meter and with only 30% of its surface covered with Nano port we could reach 1 megawatt it’s enough to run fifty thousand standard energy-saving light. In this method, we can get available drinkable water also producing blue current. There is no other sustainable method all over the world to produce current without sunlight, turbine, or fossil fuel. Water desalination is the only way to get pure water and produce electric current both with low costing.
