Using more pure water from offshore aquifers rather than ocean water has the potential to reduce desalination costs, the authors argue — with reverse osmosis, desalination costs for ocean water run between 53 cents and $ 1.50 per cubic meter, while the cost to process brackish water from offshore aquifers runs between 10 cents and $ 1.

Unlike the existing reverse - osmosis membranes responsible for more than half of the world's current water desalination capacity, the new membrane process dehydrates ions as they pass through the membrane channels and removes only select ions, rather than indiscriminately removing all ions.

Most of the 15,000 desalination plants in the world employ a technology known as reverse osmosis.

Existing desalination plants rely on reverse osmosis, vacuum distillation, or a combination of the two.
