Water desalination

Seawater desalination is an increasingly important solution to the rising water scarcity afflicting many of the world's regions. With more than 100 years of proven experience and 9 million cubic meters of water produced per day

We build seawater desalination plants and units using three types of solutions:

Thermal water desalination:
Saline content is separated by evaporating seawater in distillation systems. A process known as Multiple Effect Distillation (MED) reuses the energy generated during vapor condensation, reducing the energy consumption required to heat the water.
Whether for large municipal plants, through its subsidiary SIDEM, or for industrial units, through Entropie, Veolia is a recognized leader in MED with hundreds projects successfully delivered.

Reverse osmosis for water desalination:
Reverse osmosis involves pushing water under pressure through a membrane that retains the salt and other impurities.
The Veolia-designed, built and operated SWRO desalination facility in Sydney, Australia, third largest in the world, provides up to 15% of the city’s daily water needs. 
To protect your RO plant, we also offered preventive solutions and safety programs through our Hydrex 4000  range of chemicals.

Hybrid water desalination solutions
Increasingly, thermal desalination and reverse osmosis are being combined, an innovation that allows electricity use to be optimized and reduces production costs.
This state-of-the-art combination was implemented in Fujairah 2 (United Arab Emirates), making this plant the largest hybrid desalination reference in the world, with a capacity equivalent to 591,000 m3 of drinking water per day. It has proven to be a solution which meets the requirement for a constant high quality potable water output, despite a vast seasonal variation in the power output as well as algal bloom.
