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.
