The most important users of desalinated water are in the Middle East , (mainly Saudi Arabia, Kuwait, the United Arab Emirates, Qatar and Bahrain), which uses about 70% of worldwide capacity; and in North Africa (mainly Libya and Algeria), which uses about 6% of worldwide capacity.
What region uses desalination the most?
No other region on Earth desalinates so much water. The Middle East , according to experts, accounts for more than 60% of the world’s total desalination capacity. Other water-stressed countries, such as Morocco and Australia, have also begun to tap the oceans.

Can you drink ocean water if you boil it?
Desalination is the process of removing salt from seawater, making it drinkable. This is done either by boiling the water and collecting the vapor (thermal) or by pushing it through special filters (membrane).
What is the biggest desalination plant in the world?
At al-Jubail , the world’s largest desalination plant which makes more than 1.4 million cubic metres of water daily, treated waste brine plumes back into the Arabian Gulf.
Why is desalination bad?
What are the environmental impacts of desalination? ... Desalination has the potential to increase fossil fuel dependence , increase greenhouse gas emissions, and exacerbate climate change if renewable energy sources are not used for freshwater production. Desalination surface water intakes are a huge threat to marine life.
Can you drink desalinated water?
A floating solar still is used to desalinate small amounts of seawater, using evaporation and condensation. No, don’t take us literally! Humans cannot drink saline water. ... The process is called desalination, and it is being used more and more around the world to provide people with needed freshwater.
What are the 3 main problems associated with desalination?
Why think about desalination? There are certainly three factors: drought, climate change, and population growth .
Why are oceans salty but not lakes?
Rain replenishes freshwater in rivers and streams , so they don’t taste salty. However, the water in the ocean collects all of the salt and minerals from all of the rivers that flow into it. ... In other words, the ocean today probably has a balanced salt input and output (and so the ocean is no longer getting saltier).
Why is ocean water salty?
Salt in the sea, or ocean salinity, is mainly caused by rain washing mineral ions from the land into water . Carbon dioxide in the air dissolves into rainwater, making it slightly acidic. ... Isolated bodies of water can become extra salty, or hypersaline, through evaporation. The Dead Sea is an example of this.
Why is desalination so expensive?
Because desalination requires a lot of energy the plants are also very expensive to maintain . Energy is reported to be the largest single expense for desalination plants, accounting for as much as half of the costs to make drinking water from the sea viable.
Which country is using seawater for drinking?
Kuwait relies on water desalination as a primary source of fresh water for drinking and domestic purposes. There are currently more than six desalination plants. Kuwait was the first country in the world to use desalination to supply water for large-scale domestic use.
Where does Dubai get water?
Close to 99% of potable drinking water in Dubai comes from its desalination plants . The desalination plants process sea water to make them usable. Sea water from the Arabian Gulf is pumped into DUBAL, Dubai Aluminum factory to cool the Aluminum smelters.
Why does Saudi Arabia use desalination?
In order to overcome water scarcity, substantial investments have been undertaken in seawater desalination, water distribution, sewerage and wastewater treatment.
What are the disadvantages of desalination?
- Waste Disposal. As with any process, desalination has by-products that must be taken care of. ...
- Brine Production. Brine is the side product of desalination. ...
- Ocean Populations. ...

- Energy Use.
Why California has no desalination plant?
Experts agree that cities need diverse water supplies, but desalination plants remain controversial. Once again, California is in a drought . ... The state’s climate is becoming increasingly unstable, oscillating between periods of drought and deluge, which is making the water supply hard to predict.
