DuPont announced that FilmTec LiNE-XD nanofiltration membrane elements, the company's first offering dedicated to lithium brine purification, was named a finalist in the 2024 Edison Awards in the Resource Recovery & Environmental Conservation category.

Lithium brine purification is critical to producing batteries needed for electrification to help combat climate change. FilmTec LiNE-XD elements can help enable lithium production from resources such as salt lake brine, geothermal brine, and surface and sub-surface clay. FilmTec LiNE-XD nanofiltration membrane elements are designed to withstand harsh conditions while also yielding high recovery of both lithium and water; requiring less energy than other methods.

"With a future powered by batteries, the demand for lithium continues to rise rapidly—and so does demand for cleaner and more efficient extraction methods that can be made possible by membranes," said Verónica Garcia Molina, Global Marketing Leader, Industrial Water & Energy, DuPont Water Solutions. "We're excited and honored for this recognition of our team's dedication to innovation and sustainability."

The durability, selectivity and permeability of FilmTec LiNE-XD nanofiltration membrane elements can help enable lithium mining operations, including emerging applications such as direct lithium extraction (DLE), to help enhance lithium yield, reduce energy consumption and increase membrane lifetime compared to conventional nanofiltration membranes. Additionally, cleaning, chemical usage and disposal can be reduced in downstream lithium concentration thanks to its efficient removal of scaling impurities.

The Edison Awards is an annual competition honoring excellence in new product and service development, marketing, human-centered design, and innovation. The gold, silver and bronze winners will be announced at the 2024 Edison Awards Gala in Fort Myers, Florida, on April 18, 2024.
