Hyflux was awarded the project to develop a seawater reverse osmosis (SWRO) desalination plant in Magtaa, Algeria in April 2008 by the state-owned Algeria Energy Company (AEC) which handles the power and water privatisation exercise in the North African country. Hyflux won the project under intense competition from international contenders.
Hyflux’s partners for the project are AEC and the state-owned national water company L’Algérienne Des Eaux (ADE). The off-takers are Sonatrach and ADE.
Magtaa Desalination Plant is distinctive in a number of ways. With a designed capacity of 500,000 m3/day of desalinated water, it is one of the largest SWRO desalination plants in the world.
It features the world’s largest installation of ultrafiltration membranes for the pre-treatment process. Hyflux’s Kristal® membranes are employed for the pre-treatment stage.
The pipe laying is an engineering feat in its own right. The plant is located some 400 m away from the shoreline separated by a very challenging stretch of terrain that includes a lake, a railway track and sand dunes. In order to lay the intake and outfall pipes, a tunneling technique called pipe jacking was employed to tunnel some 10 m below sea level for the pipes to be laid and extended to the sea. Three intake tunnels, each 1.2 km long and an outfall tunnel of 1.0 km length were constructed in this manner.
