Israel Proves the Desalination Era Is Here

One of the driest countries on Earth now makes more freshwater than it needs

That is the headline of an article in the July 29th edition of Scientific American, written by  Rowan Jacobsen, Ensia.

Call it a Desali” a natural” ization breakthrough because researchers figured out how to eliminate the Achilles heel of desalination that requires costly and chemical intensive agents with a natural chemical-free process, and now Israel, has the largest reverse osmosis facility in the world and gets 55% of its water from desalination.  Here is an excerpt of the Scientific American article:

Bar-Zeev, who recently joined Israel’s Zuckerberg Institute for Water Research after completing his postdoc work at Yale University, is an expert on biofouling, which has always been an Achilles’ heel of desalination and one of the reasons it has been considered a last resort. Desal works by pushing saltwater into membranes containing microscopic pores. The water gets through, while the larger salt molecules are left behind. But microorganisms in seawater quickly colonize the membranes and block the pores, and controlling them requires periodic costly and chemical-intensive cleaning. But Bar-Zeev and colleagues developed a chemical-free system using porous lava stone to capture the microorganisms before they reach the membranes. It’s just one of many breakthroughs in membrane technology that have made desalination much more efficient. Israel now gets 55 percent of its domestic water from desalination, and that has helped to turn one of the world’s driest countries into the unlikeliest of water giants.

The article goes on to point out that Syria, facing the same drought of 2008, just kept drilling deeper and deeper until the wells and farmland collapsed, causing an exodus to cities and creating the current unrest and crisis.

So maybe, juts maybe, the solution isn’t to “bomb the hell out of ISIS” but to have the world build them as Israeli-invented Desalination plant, get refugees back to their farms and take away the desperation that drives so many to join ISIS in the first place.

Just saying…
