High-quality demineralised water

The contract, includes design and construction of the desalination plant as well as operation and maintenance for six years.

ACCIONA 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 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).

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 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.
