Seawater Desalination

What does desalination mean?

SEAWATER DESALINATION IS AN INCREASINGLY KEY SOLUTION FOR THE SCARCITY OF WATER

Seawater covers 71% of the planet surface and represents 97% of the world's water. With more than 100 years of experience, technologies and knowledge in desalination, Veolia Water Technologies supports municipalities and industries around the world in the implementation of their seawater desalination strategies.

Our all-encompassing range of water treatment solutions and seawater desalination technologies are dedicated to optimise the management of the water resources. Combined with local presence and a worldwide network of experts, we ensure our clients the best possible solutions to supply high quality water, manage brine concentrates, produce or recover energy, extract raw materials and capitalise on by-products.

Veolia Water Technologies has built more than 1,900 Reverse Osmosis desalination plants and systems in 85 countries during the last four decades that produce more than 6.5 million m3/day of fresh water for both municipal and industrial needs. As an example, the Veolia-designed, built and operated Reverse Osmosis desalination facility in Sydney, provides up to 15% of the city's daily water needs. Ours leading technologies help reduce water scarcity.

CASE STUDY: Reducing energy and protecting the environment at the Sydney Desalination Plant

At the Sydney Desalination Plant, Veolia devised and implemented a 41% reduction in energy requirements during osmosis.

As a joint venture partner with John Holland, we designed and built the plant and have a 20-year operating contract. The plant can desalinate 250, 000 megalitres of seawater a day and provides a drought proof water supply for 1.5 million Sydney residents.

The plant was built to high environmental and public health standards. Multiple safeguards protect drinking water quality and minimise the environmental impact of salty water outflows to ocean. Veolia technologies are critical to the plant's performance—for example, by providing efficient chemical pre-treatment and filtration of seawater, reverse osmosis, and water post-treatment and disinfection.
