Retaining 99.9% of the salt in seawater
Reverse osmosis is a leading-edge technology chosen by SUEZ retaining more than 99.9% of the salt dissolved in water, using pressure effects. This result is achieved by using a membrane filter that retains salt molecules, whilst letting water molecules flow through. The fresh water is collected and then undergoes numerous tests before being distributed, while the salt is diluted, before being returned to the marine ecosystem.
Inventing new seawater desalination technologies
In Masdar (Abu Dhabi), SUEZ has built a seawater desalination pilot plant that is particularly innovative and ambitious in terms of energy and environmental performance.
For Masdar, the stakes are high because the new city is at the heart of a region facing strong population growth and sustained economic development even though its water resources are limited. It has also set itself the ambition of eventually becoming a positive energy territory.
To meet these challenges, SUEZ has been working on two areas:
The implementation of a breakthrough technology with the potential to reduce electricity consumption by 25%.
The technical and economic evaluation of the various solar energy production and energy storage solutions to supply future desalination plants.
By contributing to this project, SUEZ's objective is to develop sustainable solutions for access to water, both in this arid region and in the rest of the world, in line with its desire to offer global solutions for the sustainable and intelligent management of the planet's natural capital.
With this research contract, SUEZ also wishes to consolidate its world leadership in seawater desalination by reverse osmosis. To date, the Group has built more than 260 plants equipped with this solution.
