The diagram below shows the way how to remove salt from sea water in order to make it drinkable.
First of all, it is taken from the ocean and put into the pre-treatment filter to clean. Next, this liquid is gone through the membrane which can filter impurities and salt from it effectively in a high pressure. Then, it is moved to the post-treatment which is included lime, chlorine and fluoride. Lastly, it is stored for integrating water supply system. In this stage, the water molecules is totally separated with the original water. In a pre-treatment step, the salt water can be filter in a backwash and returned to the sea. The membrane has another way as well as which is concentrating the water and return it into the sea.
It is not hard to see that these are a lot of steps to make the sea water can be drinkable.
