Arab–Israeli peace projects regional problems of acute shortage of clean fresh water in Jordan, and the rapid contraction of the Dead Sea. A new desalination plant to be built near the Jordanian tourist resort of Aqaba would convert salt water from the Red Sea into fresh water for use in southern Israel and southern Jordan; each region would get eight billion to 13 billion gallons a year. This process would produces about as much brine as a waste product; the brine would be piped more than 100 miles to help replenish the Dead Sea, already known for its high salt content. This would
Brine is purified to a desired level. Resin is then regenerated by sequentially backwashing the resin bed to remove accumulated solids, flushing removed ions from the resin with a concentrated solution of replacement ions, and rinsing the flushing solution from the resin. After treatment, ion-exchange resin beads saturated with calcium and magnesium ions from the treated water, are regenerated by soaking in brine containing 6–12% NaCl. The sodium ions from brine replace the calcium and magnesium ions on the beads. In lower temperatures, a brine solution can be used to de-ice or reduce freezing temperatures on roads. Brine is a byproduct
