New Salalah desalination plant commences commercial operation


Abengoa Agua, the water division of Spanish based international infrastructure and energy specialist, has announced the successful completion of the construction of a reverse osmosis desalination plant in Salalah.

The 113,500 cubic metres /day capacity desalination plant has been built for a consortium led by ACWA Power and also composed of Veolia and Dhofar International for Investment and Development Co SAOG.

The Oman Power and Water Procurement Company (OPWP) has acted as offtaker.

The desalination plant began to produce water in December 2020 and, once the operational tests were completed, it began its commercial operation in March of this year.

This plant reinforces the supply of drinking water to this region of southern Oman which, like others in the Middle East, suffers from water scarcity problems. In addition, the desalination plant facilities are designed to produce up to 120,000 m3/d if necessary, Abengoa said in a press statement.

The design of this desalination plant includes a very robust seawater pretreatment line composed of a Dissolve Air Flotation (DAF) plus a double stage multimedia filtration with gravity and pressure filters.

Specifically, Abengoa Agua, in consortium with Fisia Italiampianti, has been responsible for the engineering, supply and construction of this project whose scope included the seawater intake, pretreatment, reverse osmosis system with energy recovery, post-treatment, product water storage and brine discharge through an outfall.

The completion of this project consolidates the company as a leader in the international desalination sector, in which it has get important achievements in recent years due to the size, complexity and importance of the projects it has developed.

This is the second project that the company has carried out in Oman, where it already has the Barka I desalination plant, with a production capacity of 45,000 m3/d.

Currently, it has a global installed capacity of about 1.8 million m3/d that will be expanded to 4.3 million m3/d when the portfolio in execution will be completed.

Some of the projects that are under construction are considered a reference in the sector as the largest reverse osmosis desalination plant in the world, located in the Taweelah power and water generation complex, in the United Arab Emirates (UAE), with a production capacity of 909,000 m3/d.
