DOE's National Alliance for Water Innovation selected a Global Water Innovations-led team, with Trevi Systems as project partner, to demonstrate high-recovery desalination at five California sites with one transportable unit.
The mobile testbed pairs scale-ion removal with brine concentration at five California sites: Cambria, San Luis Obispo, Oxnard, Ventura County, and South Beach County.
Trevi's 25 m³/day FO/PFO mobile unit handles varied RO brines, including agricultural and oil-and-gas wastewater feeds.
Field results from all five demonstrations are peer-reviewed (Webley, Greene & Easter, AJRSP, 2026).
A transportable train lets the team characterize each feed and evaluate the complete system at the water source.
Scaling risk and residual routes begin with the existing treatment train.
Salinity and scale-forming ions vary with source and season.
Oil-and-gas wastewater is among the intended mobile-unit applications.
The program combines scale-ion removal with brine concentration in one integrated train.
Measure flow, salinity, hardness, silica, organics, temperature, and variability.
Tune upstream softening for the ions that limit membrane recovery.
Apply Trevi PFO and monitor the concentrate as conditions change.
Finish recovered water to specification and define the residual outlet.
Record performance across conditioning, PFO, polishing, and residual handling.
The range describes integrated, site-specific treatment trains; it does not establish standalone-PFO performance or guarantee another feed's result.
Results belong to the integrated treatment trains and feeds reported in the paper; they do not guarantee another site's performance.
