2. Turn ocean water into drinking water.

Solution found through reverse osmosis membranes and desalting technology.

Many countries around the world, including island nations and desert nations, have no drinkable water, or population growth is exceeding their supply of potable water. On the Mediterranean Island of Malta, as far back as 1536, the water was salty and sedimentary and drinking water came from rainfall captured in ditches and cisterns. The age-old problem of how to provide the basic necessity of drinking water for a population persists and DuPont has helped provide a solution.

DuPont is the global leader in reverse osmosis desalting technology. Reverse-osmosis systems use specialized membranes which reject dissolved impurities and salts to provide clean water.  DuPont was a pioneer in developing "permeation" membranes starting with fundamental membrane research in 1962. Using decades of experience since its invention of nylon polyamide polymers in 1938, DuPont invented the basic aramid polymers widely used by membrane suppliers today. DuPont was also the first to commercialize reverse osmosis membranes, based on durable Permasep® hollow fibers, for brackish water desalting in 1969 and seawater desalting in 1974. 

Saudi Arabia's newest desalination plants in Al Jubail will operate with more than 3,000 permeators made from a tough DuPont aramid polymer to desalt 24 million gallons of drinkable water every day from Arabian Gulf seawater
