Ashkelon Desalination Plant (Israel)


When completed, the Ashkelon reverse osmosis desalination plant was by far the world’s largest and most advanced desalination plant. With a huge capacity of up to 330,000 m3/day and with 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% to 392,000 m3/day, providing clean water for more than a million people.

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