JEDDAH – Marafiq, Saudi Arabia's leading water and electricity services operator, has contracted Veolia Water to design, build and operate the largest ultrafiltration and reverse osmosis desalination plant in the Kingdom. Under the contract, Veolia Water will generate $310 million (€232 million) in revenue for the plant's design and construction, and $92 million (€69 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 178,000 m(3) per day, the 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. “With this new reference, Veolia Water confirms its position as a leader in desalination and the reference partner for industrial entities. 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, Chief Executive Officer of Veolia Water. Marafiq operates the Kingdom's water and electricity services and is responsible for overseeing the development of the Jubail and Yanbu industrial cities designed to ensure Saudi Arabia's economic diversification. — SG
