SADARA Petrochemical Complex

With a capacity of 178,000 m3/day, this seawater desalination plant is the largest combining dissolved air flotation, ultrafiltration and 2-pass reverse osmosis process


Sidem was awarded a $310 million contract by Marafiq, Saudi Arabia's leading water and electricity services operator to design and build the largest ultrafiltration and reverse osmosis desalination plant in Saudi Arabia.

With a capacity of 178,000 m3 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. 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, Sidem has designed a plant combining two seawater treatment solutions: ultrafiltration and reverse osmosis.

Veolia group also secured a separate 10-year operation contract as part of the deal, extendable to a further 20 years.

Sidem is a subsidiary of Veolia Water Solutions & Technology and the world leader in the supply of seawater desalination plants based on multiple effect distillation and reverse osmosis processes.
