Efficient seawater desalination is one of the most effective answers to the water crisis many countries face, and with water stress growing worldwide, its role is likely to keep increasing.
Thanks to advanced technology, countries are now using vast seawater reserves to produce drinking water, and despite the challenges, improving technology is making seawater desalination increasingly efficient.
There are many success stories in efficient seawater desalination, and learning about them helps to show how effective the technology is.
1. Ras Al-Khair, Saudi Arabia
One of the largest desalination facilities in the world, located on the coast north-west of Jubail. The integrated complex includes 2,400 MW of power generation and can produce around 1,036,000 m³ of drinking water a day, using both thermal and reverse osmosis (RO) technology.
2. Sorek 2, Israel
One of the world’s largest seawater desalination plants, with a reported capacity of around 580,000 m³/day. Located near Tel Aviv, it uses reverse osmosis, the most widely used and efficient desalination method, and has improved on existing technology in water quality, cost and environmental impact.
3. Carlsbad desalination plant, USA
Located in California, the Carlsbad plant is the largest in the western hemisphere. Using reverse osmosis, it can produce 50 million US gallons (around 190,000 m³) of desalinated seawater a day, supplying fresh water to southern California.
The plant was built in response to falling water levels and the need for an economically viable source of fresh water, and it has become more efficient, environmentally responsible and cost-effective over time.
4. Tianjin Beijiang power station, China
This facility combines a power station, a seawater desalination plant and salt production from brine. It can produce 200,000 m³/day of water using thermal desalination and uses waste heat from the power station to improve energy efficiency.
5. Umm Al Quwain (UAQ), UAE
One of the largest standalone reverse osmosis plants in the world, with a capacity of around 682,900 m³/day.
Why seawater desalination?
The need for seawater desalination comes from several critical factors, including water scarcity, population growth and environmental pressures, with the depletion of natural freshwater sources one of the main drivers.
These are some of the reasons why efficient seawater desalination is the right solution for communities, industry and the environment:
- Water scarcity: the main reason desalination is needed. Many countries face water shortages, and turning seawater into drinking water is one of the most effective solutions.
- Population growth: existing water resources are not enough to supply a growing population, and desalination offers a long-term source of drinking water.
- Climate change: it affects water availability, rainfall patterns and weather conditions, and desalination is a strong option for dealing with climate-driven water scarcity.
