About

NEXT TFX, Inc. develops ultra-high-pressure reverse osmosis (UHPRO) membranes for desalination and critical mineral recovery. Its patented three-layer membrane uses a resin-based coating that resists compaction at pressures traditional RO elements cannot reach, so operators can concentrate brine much further in a single pass. The technology was invented by co-founder and CEO Dr. Eric M.V. Hoek at UCLA's Samueli School of Engineering, and the company was founded in 2025 in Los Angeles with co-founder and VP of Operations Pat O'Brien.

A compaction-resistant membrane rated to 120 bar with under 5% compaction loss and stability to 200 bar, delivering roughly double the performance of conventional reverse osmosis at substantially lower energy use, which makes lithium recovery from high-salinity brine and minimum-liquid-discharge desalination practical.

Product

UHPRO membrane platform

Water treatment membrane

Ultra-high-pressure reverse osmosis membranes built on a three-layer structure with a proprietary resin-based coating, for desalination and for extracting lithium and other minerals from high-salinity brine.

  • Operates at pressures up to 120 bar with under 5% compaction losses, stable to 200 bar
  • Greater than 99% rejection at 180,000 mg/L salinity
  • Tolerates temperatures up to 85C (185F)

Built for

Lithium and critical-mineral producers, water utilities and government agencies, and desalination facility operators
