Geography: Desalination technology:A savior Of water from water
@prettyprecyOn a very cool evening in the house, my friends and I got talking about the growing demand of portable water in the world today especially in modern cities. Portable water business is fast growing and it seems that the fresh water sources are gradually Diminishing especially in developed and developing countries and that got us talking about sea water .i remember we do have a slang which says 'water water everywhere non to drink". Sea/ocean water body are the largest water bodies in the world and yet it is unfit for direct human consumption because of the high salt content in these water bodies. The salt content in these saline water when consumed directly into the body can damage the liver, intestine and kidney as well and this brings us to what desalination means. Desalination is a very important concept in hydrology and it can be defined as all the chemical processes involved in the removal of salt and other natural compounds from water in order to get fresh portable water.
