Taking the Salt Out of the Sea

A novel R&D Award–winning membrane technology developed by Lawrence Livermore National Laboratory in partnership with Porifera, Inc., in Hayward, California could lead to more cost-effective filtration processes for water desalination and reclamation than are available today. The highly permeable, chemically inert membranes are composed of carbon nanotubes, which are hollow, seamless cylinders. Extremely smooth interior walls allow liquids and gases to rapidly flow through the nanotubes, while rejecting larger molecules. Development of this technology derived early support from LDRD researcher Olgica Bakajin’s “Carbon-Nanotube Permeable Membranes."
