Veolia Water Solutions & Technologies has been selected by Marafiq, Saudi Arabia's leading water and electricty services operator, to design, build and operate the largest ultrafiltration and reverse osmosis desalination plant in Saudi Arabia, the company announced Tuesday.
With this contract, Veolia Water will generate $310 million in revenue for the plant’s design and construction, and $92 million in revenue for its operation for 10 years, with an option to extend the contract for a further 20 years.
With a capacity of 178,000m3 per day, this new plant will supply the Sadara petrochemical complex built by Dow Chemical and Saudi Aramco in Jubail Industrial City II and is due to come on stream in June 2015. Dow Chemical and Aramco will produce solvents and glues for the automotive and packaging industries at the Sadara site.
The water supplied will be used in this immense facility’s two cooling towers and as boiler feed water. To meet the very strict water quality standards required by Marafiq and minimize this new plant’s impact on the environment, Veolia Water, through its subsidiary Sidem, has designed a plant combining two seawater treatment solutions: ultrafiltration and reverse osmosis.
After an initial treatment phase involving dissolved air flotation to capture the suspended particles in the water and ultrafiltration, the water will then be desalinated by reverse osmosis membranes before being remineralized. The combination of these various processes will ensure a secure water supply, limit the risk of plant failure and extend its lifespan, while at the same time reducing the site’s energy requirements and costs, Veolia says.
“Veolia Water’s unique expertise and technology were the deciding factors in meeting the requirements of these exacting clients Marafiq, Saudi Aramco and Dow Chemical,” said Jean-Michel Herrewyn, CEO of Veolia Water.
