Dupont Facilitates Subsea Desalination

DuPont has entered into a collaboration with Waterise to provide seawater reverse osmosis membranes and expertise to the company’s subsea desalination plants.

Subsea reverse osmosis (RO) desalination presents a sustainable and more economical new way to turn seawater to freshwater. As subsea desalination leverages the natural hydrostatic pressure found at the depths of the sea to run the reverse osmosis, it reduces the energy requirements of conventional RO desalination by 40%. It also requires 80% less coastal land than land-based plants, presenting a viable option for communities with limited space.

From an environmental perspective, subsea desalination requires lower amounts of pretreatment chemicals and eliminates the discharge of concentrated brine into coastal waters.
