Desalination and Water Treatmentتحليـــة ومعالجة المياه 

Description of the Course:
(Study of the scientific, technological as well as economic aspects of desalination of seawater and brackish water with special reference to local conditions. Recovery of minerals as by-products. Solar energy utilization) 

Water Treatment  
Water treatment describes   those processes used to make   water   more acceptable for a desired   end-use. These can include use as   drinking water  , industrial   processes, medical and many other uses. The goal of all water treatment process   is to remove existing   contaminants   in the water, or   reduce the concentration of such contaminants so the water becomes fit for its   desired end-use. One such use is returning water that has been used back into   the natural environment without adverse ecological impact 
The processes involved in treating water for drinking purpose may be solids separation using physical processes such as settling and filtration, and chemical processes such as disinfection and coagulation. Biological processes are also employed in the treatment of wastewater and these processes. wikipedia-site

Desalination:
The removal of dissolved salt and other minerals from water.
