DESALINATION

WHAT IS DESALINATION

• Desalination: Desalination is a cycle that filters mineral components from saline water. Desalination refers to the extraction of salts and minerals from a consisting substance, as in soil desalination, which is an issue for agriculture

PROS OF DESALINATION

• It’s method is proven and effective.
• It preserves fresh water supplies
• It has an incredible amount of ocean water for a source
• Desalination plants are in safe locations
• It doesn't depend on any changing factors

CONS OF DESALINATION

• Its plants are expensive to build.
• It is a very expensive process
• It requires a lot of energy to process.
• Its resulting brine can have a dramatic environmental impact
• It contributes to the world’s greenhouse gases
• It might risk producing contaminated water

REVERSE OSMOSIS

REVERSE OSMOSIS

• Reverse Osmosis uses 3 steps
• Reverse Osmosis creates fresh water using salt water
• Reverse Osmosis systems are inexpensive
• The government in Pakistan built more than 300 Reverse Osmosis plants.

THERMAL DESALINATION

THERMAL dESALINATION

• Thermal Desalination is the process of making salt water fresh water by using energy to heat the water to boiling point making the water evaporate. This leaves back the salt and only takes the water. They then cool the evaporated water in a separate tank allowing the water to condense along the tank creating pure water.

EXAMPLES

• Desalination plants operate in more than 120 countries in the world, including Saudi Arabia, United Arab Emirates, Spain, Malta, Portugal, Greece, Italy, India, China, Japan, and Australia.
• The State Of Florida has 35 desalination plants providing 245 million gallons per day of safe drinking water.
• Al Yasat Al Soghrih Island 2M gallons per dayor
• The Tampa Bay Water desalination project is made to run at capacity of 25 million US gallons

SUCCESS RATES

• According to the International Desalination Association, “in June 2015, 18,426 desalination plants operated worldwide, producing 86.8 million cubic meters per day, providing water for 300 million people.”
• In Spain 20 desalination plants are to open providing more than 1% of all of Spain’s Water needs.
• The most important users of desalinated water are in the Middle East, which uses about 70% of worldwide capacity; and in North Africa, which uses about 6% of worldwide capacity.

Our position

We believe that desalination should be used in areas of the world that do not have fresh water at their disposal, and only have salt water around them. Desalination greatly affects our planet and our water system. For those reasons we believe that desalination should not be used in areas that have great amounts of fresh water so to preserve our planet and way of life.
