The diagram depicts the process which removes salt and other objects from seawater in order to make it drinkable. Overall, this process of desalination involves several distinct stages including filtration, purification, storage and distribution.
As is shown in the illustration, seawater is pumped into the pre-treatment filter which separates debris such as garbage, marine life, and rocks from the water before sending them back to the sea as backwash. Meanwhile, the remaining water is sent to the next filter. There it is forced through a membrane at high pressure so as to allow water molecules to pass through while other minerals and contaminants are blocked and returned to the sea as seawater concentrate.
Next, the freshwater is post-treated with lime, chlorine, and fluoride in order to kill any harmful bacteria and make it completely safe for use. Following this, the water is stored where it will then be distributed to the public bottles and faucets.
