Trevi develops renewable hyper-saline brine concentration with optional energy and critical mineral recovery. Founded in 2010, the company pioneered low-energy forward-osmosis desalination and now delivers complete treatment trains for the most challenging water on earth.
Trevi Systems, Inc. is a Sonoma County, California technology developer that first pioneered the development and commercialization of low-energy, sustainable forward-osmosis water purification: desalinating seawater and brackish water, and cleaning industrial and municipal wastewater.
Building on that experience, Trevi has evolved into a provider of renewable hyper-saline brine concentration for minimum and zero liquid discharge, with optional energy and critical mineral recovery, across a range of markets and industries.
Trevi is funded by insiders and corporate partners.
An innovative team of scientists and engineers committed to delivering sustainable desalination and brine-concentration technology to market, with backgrounds spanning membrane science, industrial water systems, manufacturing, and finance.
Trevi maintains a significant portfolio of granted, pending, published, and licensed patents across the United States and internationally, centered on osmotic fluid purification and solvent recovery. The portfolio protects the company's proprietary methods and the investment behind them.
Trevi's flagship 500 m³/day solar-powered forward-osmosis seawater desalination plant operates at the Natural Energy Laboratory of Hawaii Authority site at Keahole Point, Kona.
