The desalination plant will be operated by ACCIONA Agua for the next six years, with an estimated daily production of 12,000 m3.

ACCIONA Agua has completed construction of a desalination plant that will provide high-quality demineralised water to the Sarlux refinery (part of the Italian energy group Saras Spa), located in Sarroch, near Cagliari, in Sardinia (Italy). The contract, worth 22 million euros, includes design and construction of the desalination plant as well as operation and maintenance for six years, with a possible three-year extension.

The desalination plant has a daily production capacity of 12,000 m3 of demineralised water through such processes as ultrafiltration, reverse osmosis and electrodeionisation (a continuous process to obtain ultra pure water without the need for chemicals).

The treated water will be used in industrial processes carried out by the Italian energy company at its refinery near Cagliari (Sardinia), one of the largest and most complex facilities of its type in Europe.

With a total footprint of approximately 1,260 m2, it is the largest desalination plant for industrial use in the Mediterranean. In the design and construction of the plant, ACCIONA Agua incorporated solutions that minimise environmental impact, costs and installation times, and improve efficiency in overall operation by reducing pressure losses and significantly optimising energy consumption, among other factors.

This plant is a step forward in the Company’s strategy to diversify its industrial project portfolio in Italy, where it has had a presence since 1999 and where it has extensive experience in construction, operation and maintenance of water treatment facilities.
