Desalination Plant is a natural continuous process, which is essential for the water recycling. If we were to consider rain or snowfall on the ground, which finally flows either into the sea or goes back to the atmosphere through evaporation or percolates into the sub-soil, is a process of natural desalination. Living beings use this water directly from rain or from river, lakes or springs. When the surface water travels down towards the sea it dissolves minerals and other materials and becomes salty. Once it flows into the oceans, natural evaporation removes part of the water into the atmosphere as clouds, while remaining water available in the ocean becomes very salty. The evaporated water from the ocean is restored back to the earth in the form of rain or snow, which again goes back to the ocean and the cycle continues.
