Turning Seawater into Fresh Water

Desalination Technology for Turning Seawater into Fresh Water

Desalination technology that turns seawater into fresh water usable in daily life is classified into two methods: the evaporation method, in which fresh water is produced by evaporating seawater, or the membrane method, in which fresh water is produced by passing seawater through a reverse osmosis membrane.

Solving the World’s Water Shortage

Since 1970, Hitachi Zosen has been building desalination plants for Middle East countries and remote islands in Japan who suffer with chronic water shortages.
The total amount of fresh water produced daily by all of the plants that Hitachi Zosen has constructed throughout the world (approximately 1.2 million tons) supports daily water needs for approximately 4 million people.
In the Sultanate of Oman, our plants support daily water needs for 1 of 3 of total population.

Solving the World's Water Shortage

The World’s Worsening Water Shortage

Of the 6.6 billion people in the world today, 1.1 billion are in a serious situation where they cannot secure a stable supply of drinking water.
The United Nations predicts that, in 2025, the world’s population will increase to approximately 8 billion and 5.5 billion of them will live in regions with a water shortage.
