Many countries lack access to safe drinking water sources but they do not lack the sea, where these countries are next to one of the sea, and what distinguishes seawater, it should not for drinking and is not suitable for irrigating crops due to the salinity of the sea water, but if we get rid of salinity and We must approach can we get drinking water and Ready to water irrigation so these countries to resort to desalinate seawater and called for the desalination of salt water is converted to water flowed net free salinity and minerals and is ready to drink and to separate salt molecules to water erosion becomes drinking water and desalination processes are a number of ways and Saudi Arabia one of the most famous countries desalinate desalination of water and especially the Red Sea.

Distillation process based on the conversion of water from a liquid to a gaseous state which is condensed and turns into a liquid state, and to clarify the most is the so-called desalination plants of the and water is a very large reservoirs are seawater have and where the shell is subjected to high temperatures up to boiling where when the water reaches the boiling point is transformed into steam and the steam is molecule water which does not contain salts as they remain concentrated in the bottom of the tank, and the water vapor passes through Onbabeb until thickened inside the tubes when subjected to low temperature by cooling and into a medium to conduct water inside the tube is in the tanks district and others are treated with ozone salts and minerals and bacteria to become clean, then pumped through pipes and distributed in homes and neighborhoods of cities.

 Method desalination of seawater through the membranes and for the process where they are pumping large quantities of sea water from salt water after collected in tanks and using the pump is Sea water pumped through the course containing membranes and their function is to separate the salt water and called it the way in which the appointment execute salts bottom of the tank and are Trha through a special course and then move the water that was at the appointed Chihaa CPU and Pmaljh Mieh bacteria and converted to potable water, or is pumped into the tanks to be Rey and neighboring agricultural areas, refers to salts were removed to be returned to the first tank until the water filter with the new amount of water and sometimes are processed and converted to pure sodium chloride.
