The world's largest desalination plant is located in Saudi Arabia (Ras Al-Khair Power and Desalination Plant) with a capacity of 1,401,000 cubic meters per day. [41] Desalination is currently expensive compared to most alternative sources of water, and only a very small fraction of total human use is satisfied by desalination. [42]
Right now, 16,876 desalination plants in 177 countries produce enough desalinated water to support up to 972 million people per day, which equates to only 1% of the world’s clean water supply ...
Multi-stage flash distillation (MSF) is a water desalination process that distills sea water by flashing a portion of the water into steam in multiple stages of what are essentially countercurrent heat exchangers. Current MSF facilities may have as many as 30 stages.
The first desalination plant in Mexico was built in 1960 and had a capacity of 27,648 m 3 /day. [7] As of 2006, there were 435 desalination plants in Mexico with a total capacity of 311,700 m 3 /day. [74] One of the world's largest desalination plants (380,160 m 3 /day) is planned for Rosarito. [75]
Seawater desalination requires more energy than the desalination of fresh water. Despite this, many seawater desalination plants have been built in response to water shortages around the world. This makes it necessary to evaluate the impacts of seawater desalination and to find ways to improve desalination technology.
China is working to meet the country's growing demand for fresh water by building and improving desalination plants. In doing so the nation is on a path to growing the next big industry, and ...

Schematic of a multiple effect desalination plant. The first stage is at the top. Pink areas are vapor, lighter blue areas are liquid feed water. Stronger turquoise is condensate. It is not shown how feed water enters other stages than the first. F - feed water in. S - heating steam in. C - heating steam out. W - Fresh water (condensate) out.
