Reverse osmosis desalination

Degremont was historically a groundbreaker in desalination by reverse osmosis and now has more than 250 facilities to its name, producing some 2 million m³ of water every day. In 2006 the Group won two major contracts: one for Barcelona in Spain, in partnership with AGBAR, and one for the Barka 2 complex in Oman, for a capacity of 120,000 m³/d. In 2006 Degremont also delivered facilities producing 45,000 m³/d and 18,000 m3/d to customers in Chile and Curaçao (Dutch Antilles). 

A pioneer in the use of reverse osmosis desalination – its first facility, on the Ile de Houat (France), opened in 1969 – Degremont offers customers well-tested solutions in this field, whether standard or custom-built. An offering that combines all the Group’s expertise in water treatment and professionalism as a builder and operator. With 250 facilities already in service and 520 experts in design, construction and operation, Degremont commits to fast delivery of efficient, reliable facilities at optimum investment and operating cost. Degremont designs original processes and incorporates the most efficient technologies available to design technical solutions tailored to its customers’ needs.

With a wide range of products at their disposal, the Group’s desalination experts select the best technical combination for the job. Their goal is to optimise every treatment stage, but the purification stage is the key. This is because the throughput of the membranes, and hence the plant’s smooth running, reliability and robustness, depend on the purity of the water reaching the membranes.
