Ashkelon Desalination Plant (Israel)


When completed, the Ashkelon desalination plant was one of the world’s largest and most advanced  membrane-based desalination plants.  With a huge capacity and extremely high efficiency levels, the Ashkelon desalination plant achieved one of the world’s lowest-ever prices for desalinated water. In 2010, due to the unmatched success of the plant, it was expanded by nearly 20%, providing potable water for roughly 15% of Israel’s daily consumption.

The Ashkelon plant proved IDE to be the leader of mega-sized SWRO desalination projects.
