Desalination by reverse osmosis

By 2030, almost one half of the world’s population, or four billion people, will be short of fresh water. Only 3% of the water on Earth by volume is fresh. Therefore, salt water is an indispensable natural resource for the production of drinking water. Are you looking for innovative solutions to secure the long-term supply of drinking water? Desalination by reverse osmosis meets the demands for economic and environmental performance.

Made-to-measure facilities

Implementing virtuous and sustainable desalination facilities

SUEZ builds, equips and operates made-to-measure desalination facilities. The 255 desalination plants that we have built and commissioned all over the world produce more than 4.2 million m3 of fresh water per day, supplying 10 million inhabitants.

 

Each facility is designed as a unique and original solution to individual problems, but they all share the same quest for economic and environmental performance through the use of high-precision technologies.

Design and build that rise to your challenges

SUEZ can call on its expertise as a constructor-operator to offer competitive solutions that are designed and built to meet your particular needs and for each type of water to be treated.

 

Perfectly designed desalination facilities

  • Desalination facilities that produce drinking water, irrigation water or process water from sea water or brackish water,
  • Standardised small or large facilities,
  • Containerised modules with an aggregate capacity adapted to the required production volumes.

Riyadh (Saudi Arabia):

A – pretreatment on dual-media filters (2 containers)
B – treatment by reverse osmosis membranes (2 containers)
C – final treatment and feed pumps (1 container)

 

Each module with an individual production capacity of 5,000 m3/h is made up of five containers: two for the pretreatment on dual-media filters, two for the treatment by reverse osmosis membranes and one for the final treatment and the feed pumps.

Packaged equipment and technologies

  • To boost the performance of the reverse osmosis and the pretreatment, according to the degree of salinity and the concentration of organic matter.
  • To design modular, compact facilities that can come onstream quickly and are easy to operate.

Adapted operation and service solutions

  • Day-to-day supervision,
  • Optimisation of all the facilities in the desalination plant: pretreatment, energy consumption, membrane washing, etc.
  • Personalised services: supply of spares, refurbishment, staff training, etc.

 

Seawater desalination plants

SUEZ can supply desalination plants built to meet your needs and according to the type of water to be treated. These plants use innovative technologies that optimise the processes, cut operating costs and reduce environmental impacts.

Boosting economic performance by anticipating and innovating

SUEZ guarantees the competitive performance of your desalination facilities by proposing breakthrough technologies, high quality solutions and optimised deployment cycles.

  • Solutions that are original from the technological perspective, but also in terms of the financing, the contracts and the logistics, all with a view to cutting your investment costs,
  • Short deployment cycles that bring your high-performance and reliable desalination plants or units onstream quickly. Examples include the 33 x 5,000 m3 per day desalination modules, producing a total of 165,000 m3/day on 14 sites, that were designed, built, installed and started up for the Riyadh conurbation in Saudi Arabia in the record time of 6 months, or the plant in Melbourne, with a capacity of 450,000 m3 per day, that was built in 37 months.
  • Technologies in the forefront of innovation that optimise processes and cut operating costs,
  • Operating support tools that secure the production of fresh water and continually optimise operating costs,
  • Partnerships that jointly manage water and sanitation services, with a view to optimising costs and limiting ecological footprints.

Limited environmental footprints

SUEZ’s desalination facilities use high-technology processes to optimise their energy consumption and to protect the environment:

  • Equipment selected for its energy efficiency,
  • Energy recovery systems that reduce overall consumption,
  • Desalination facilities powered by wind and photovoltaic energy,
  • Innovative treatment of brine prior to dispersion or transfer to wastewater treatment plants,
  • Original solutions to protect the land and marine flora and fauna, in particular in terms of water catchment and the dispersion of brine.
Innovative solutions

50 years of innovation in desalination

As a pioneer of reverse osmosis desalination technology, SUEZ has been designing and developing innovative technologies since 1969 to optimise processes and to reduce operating costs and environmental impacts in order to produce drinking water from salt water in an ecological and sustainable manner.

Intense R&D activity

SUEZ anticipates future needs and continues to optimise its existing systems in order to develop new treatment solutions, new diaphragms or new alternative forms of energy.

 

Today, these technological advances enable SUEZ to optimise both the capital outlay and the operating costs:

  • Tools to simulate the operation of the desalination plant in order to test and configure automatic control systems in advance for faster commissioning,
  • Ranges of standardised components that are immediately operational for faster construction and lower investment costs,
  • Tools that model optimisation options to increase the efficiency of the reverse osmosis facilities, with a view to continually improving economic and environmental performance.
