2. Guiding Questions
• What is Desalination?
• Where is it used in the world?
• How do other countries use desalination?
• What are the benefits/enviromental
Impacts?
• How can we take what other countries are
doing and apply it in America?
3. What is Desalination?
• Desalination is a method of removing salt, saline
and minerals from unpurified water to become
drinking water.
4. Methods of Desalination
There are three main methods of
Desalination
1. Reverse Osmosis (RO).
2. Vacuum distillation.
3. Multi-stage flash distillation.
The method that is used most frequently is
RO.
11. Worlds Most Significant
Desalinators
• Israel – largest seawater Reverse
Osmosis Plant in the world.
• Spain - has the largest Desalination
capacity in the western world.
• United Arab Emirates – has the worlds
largest Desalination plant in the world .
12. Jebel Ali,
United Arab Emirates
On April 8, 2013 the largest Desalination
Power plant opened in the United Arab
Emirates
• Largest Desalination plant in the world.
• Method: Multi- Stage Flash Distillation.
13. Jebel Ali,
United Arab Emirates
• The plant is
located near a
large body of
water, Persian
Gulf.
14. Jebel Ali,
United Arab Emirates
(con’t)
• Produces 300 million cubic meters of
water per year.
• It produce energy and is a desalination
facility.
Special Feature: Produces energy that
aids in the desalination process
15. How do other countries
use Desalination ?
• Household Uses
• Drinking & Bathing
• Agriculture
• Manufacturing
• Medical & Firefighting
16. What are the benefits ?
There are many benefits to desalination
• It can produce large amounts of water in areas
where freshwater is limited.
• Recreational uses in arid areas.
• Clean water improves food production.
• Clean Water reduces the spread of diseases.
17. Environmental Impacts
• Uses High energy/some burns fossil fuels.
• Intake pipes suck in fish and sealife.
• Outflow is brine – high content of salts, acids,
etc.
• Heavy metals are passed to humans through
seafood.
18. How can we use what
other countries are doing
and apply it in America?
19. Uses in America ~ Benefits ~
1. We could use it as an
alternate water source • Wildlife, Recreational
to using freshwater uses,
from our aquifers.
• Air Quality would improve
2. Solar Powered
Desalination – Would
be less of an impact to
the atmosphere by not • Provide drinking water in
releasing harmful high populated areas
gases.
3. Build Desalination in
high populated areas.
