Lockheed Martin has obtained a patent from the U.S. Patent and Trademark Office to commercialize its filter technology, designed to remove salt from water.

The company designed the Perforene material to remove sodium, chlorine and other salt molecules from seawater and other sources to produce drinkable water, Lockheed said Monday.

“The Perforene filtration solution is just one example of Lockheed Martin's efforts to apply some of the advanced materials that we have developed for our core markets, including aircraft and spacecraft, to global environmental and economic challenges,” said Ray Johnson, Lockheed senior vice president and chief technology officer

Perforene comprises of nanometer-sized holes on a graphene membrane that traps ions as water passes through.

Other applications of Perforene include capturing minerals through its size-specific holes, according to Lockheed.

Lockheed is seeking filter manufacturers to commercialize and produce the material at scale.
