Forward Osmosis · 82 Patents · Validated by DOE
One platform concentrates hyper-saline brine for critical-mineral recovery and produces fresh water at the same time. Proven in the field, driven by low-grade heat.
Forward osmosis concentrates lithium-bearing brines using low-grade heat instead of evaporation ponds, recovering the water and delivering a concentrated mineral stream. Domestic supply from water we currently throw away.
AI data centers are colliding with local water limits. Trevi's FO platform turns seawater, brackish groundwater, and reuse streams into high-purity cooling water, driven by the waste heat the facility already produces.
One brine-concentration platform, six water problems. Every sector below has a stream too salty, too dirty, or too expensive for conventional treatment.
High-purity cooling make-up water from seawater, brackish, and reuse streams, driven by the facility's own waste heat.
Evaluating conditioned mine and tailings-derived water for site-specific water recovery, dissolved-solids concentration, and residual management.
Heat-driven FO and PFO for pretreated, high-salinity produced water, recovering water and reducing residual brine through a site-specific treatment train.
Concentrating RO residuals to recover water and reduce the liquid stream that remains.
Brackish and drainage water recovery for irrigation, run as NAWI mobile pilots across California.
Chemistry-specific treatment trains for saline effluent, RO concentrate, boron, and organics.
Batteries, magnets, and grid storage are multiplying demand for lithium and rare earths while refining stays concentrated in a handful of countries. Every new hard-rock mine takes a decade to permit. Every new evaporation pond takes square miles of land and one to two years of sun before it yields product.
Meanwhile, geothermal plants, oilfields, desalination plants, and mines bring mineral-bearing brine to the surface every day, then pay to dispose of it. Trevi treats that brine as the orebody: concentrate it with low-grade heat, hold the minerals, give the water back.
Recoverable value depends on chemistry. It is confirmed by assay, not assumption.
4th-generation FO seawater plant with a concentrated-solar thermal array. The largest documented forward-osmosis plant, running 60% recovery on open-ocean seawater.
High-recovery thermal FO treating oil & gas produced water. Solar-driven, minimal liquid discharge.
Two-year, $3M renewable desalination study for Masdar's energy-efficient desal program. FO proven on Gulf seawater.
Solar-powered forward osmosis with molten-salt thermal storage. Desalination that keeps running after sundown.
Mobile FO unit treating agricultural and oil & gas wastewater across California sites under the National Alliance for Water Innovation.
Standard FO system operating at KISR's desalination research laboratory in one of the world's hottest, saltiest environments.
Forward osmosis only works if you control the parts that make it work. Trevi designs and manufactures its own draw chemistry, its own heat exchangers, and its own brine train, so each one is matched to the feed and the heat a site already has instead of specified out of a catalog.
The draw solution does the pulling. AquaDraw is a thermo-responsive polymer that holds an osmotic gradient across the membrane, then separates into two phases under low-grade heat, releasing clean water and re-concentrating itself for the next pass.
Metal exchangers corrode in the acidic streams mining and heavy industry produce. ThermoSnare moves heat through thin polymer walls instead, with countercurrent geometry making up for what polymer gives away in conductivity. Capacity grows by adding modules.
Concentrating hyper-saline brine far enough that critical-mineral recovery pays is a sequencing problem, not a single machine. SaltVault is Trevi's rapidly deployable brine platform: five technologies chosen and sized against the feed chemistry and the discharge target.
Critical minerals, water security, and data center growth converge on one platform. Secure the supply before it's scarce.
