The diagram provides information about the process of changing sea water to drinking water.
 
The first of all, the sea water is taken from ocean. In the next step, the saltwater is moved through a pre treatment filter. After that, some of the unusable seawater is returned to the ocean by a filter backwash while the filtered saltwater is forced through a membrane which the only water molecules are able to pass at high temperature. At the same time, some of impurities and salt molecules are reversed to the sea through a seawater concentrate. Following this, the pure water is cleaned with lime, chlorline and fluoride in a post treatment tank. Lastly, the drinkable water is stocked in a storage tank before it is integrated to water supply system.
 
To sum up, there is various stages in treatment the drinking water beginning with taking the sea water and culminating in delivering them to consuming. (18mins / 154 words)
