Águilas-Guadalentín Desalination Plant

We designed, built, and since 2011 have run the desalination plant in Águilas, Murcia, the second largest in the world. This inverse osmosis desalination facility can produce 210,000 m3 of water a day, using sustainable, eco-efficient systems. It produces desalinated water for high yield agriculture in the provinces of Alicante, Murcia and Almeria, with the capacity to irrigate approximately 16,000 hectares.

The plant incorporates important distribution and pumping systems so the water can reach different users. It also features advanced systems for the diffusion and dissolution of brine in the sea, helping to protect the environment.

The treatment process spans four phases: pre-treatment by means of double filtration (gravity and pressure), double pass reverse osmosis to eliminate boron; recovery of energy using isobaric chambers; remineralization.
