What is desalination?
Desalination is the process of removing dissolved salts and minerals from seawater or brackish water.

What is brackish water?
Brackish water refers to water supplies that are more saline than freshwater, but less salty than seawater. Typical seawater has 3-3.5% dissolved salt, brackish water is 1-2% salt.

Why should we desalinate water?
More than 300 million people around the world rely on desalinated water for some or all of their daily needs. An increasing number of communities facing water supply challenges due to increasing demand, drought, depletion and contamination of groundwater, and dependence on a single source of supply. Desalination may need to be considered as an additional source of water as part of an overall plan to manage resources.

Benefits?
The increasing demand for water along with an increasing number of drought events means that many regions no longer have reliable water supplies. Desalination can help relieve stress on existing conventional surface water and groundwater supply sources.

Is desalination affordable?
The affordability of desalination depends on the quality of the source water and a host of other factors. Advances in desalination technologies in recent years have reduced costs considerably.

What are the evironmental impacts of desalination?
Conventional desalination involves use of significant amounts of toxic chemicals which have to be removed prior to discharge. The concentrated brine also has to be controlled. Typical processes require large energy inputs resulting in approximately 1.6kg CO2 per cubic metre of fresh water produced.

Is desalinated water drinkable?
Yes

How much water comes from desalination?
According to the International Desalination Association the total worldwide installed desalination capacity represents 80 million 
m3/day, of which 31% is obtained by thermal desalination.
