What process is used to desalinate ocean water?

distillation
The traditional process of desalination is distillation, i.e. boiling and re-condensation of seawater to leave salt and impurities behind. Currently there are two technologies with more desalination capacity in the world, multi-stage flash distillation and reverse osmosis.

What are the disadvantages of the desalination process?

The disadvantages of desalination are causing many people to think twice before starting desalination projects.

• 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.
• Health Concerns.
• Energy Use.

What are two problems with using desalination to produce freshwater from saltwater?

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.

Where does desalination water originally come from?

Desalination technology started with the simple premise of boiling water. The first desalination plant, built in England in 1945, heated water so it evaporated as steam, leaving the salts behind, and then cooled down and condensed as freshwater.

What are the advantages and disadvantages of desalinated water?

Which country has desalination plants?

Desalination plants operate in more than 120 countries in the world, including Saudi Arabia, Oman, United Arab Emirates, Spain, Cyprus, Malta, Gibraltar, Cape Verde, Portugal, Greece, Italy, India, China, Japan, and Australia.

Who created seawater desalination?

Alexander Zarchin
Alexander Zarchin (1897–1988) was a Ukrainian-Israeli chemist and inventor. He is most noted for inventing a process of sea water desalination.

Did ancient people desalinate water?

Distillation desalination is one of mankind’s earliest forms of water treatment, and it is still a popular treatment solution throughout the world today. In ancient times, many civilizations used this process on their ships to convert sea water into drinking water.
