The water is one of the most important recourses in the world because all living been are composed of from 50% to90% water who lost and need to replace it also this water is used to produce many kinds of products and for this reasons is necessary have fresh water. Besides, the fresh water is the kind of waterthat can be consumed by people, having as characteristics at a pH between 6 and 8 and besides to be free from salts and pathogens. In this moment in the world there exist a several problems for a biglack of fresh water being only 2.5% of the water in the world safe to drink for this reason today this problem is critic, many underdeveloped countries and remote areas are suffering for this lack offresh water and also this problem is stopping the development of many industries and treating the life of a lot of people. To solve this problem there exist a process that can turn salt water into freshwater safe to drink and useful in the industry and this is the water desalination.
Water desalination is a process by which salt is removed from seawater. Besides this process takes place on thedesalination plants because due to the presence of salt on seawater is not freshwater (water drinkable). On the other hand, plants seawater desalination have operated for many years, but the process was...
