Two markets — one platform

Two Expensive Problems. One Loop.

The same forward-osmosis loop that concentrates critical minerals also produces high-purity water — two programmes of work running concurrently on one proven platform.

Critical Minerals · 01 / 02

Lithium From the Brine We Already Have

Forward osmosis concentrates lithium-bearing brines using low-grade heat instead of evaporation ponds — recovering the water and delivering a concentrated mineral stream on a footprint measured in acres, not square miles. Domestic supply from water we currently throw away.

Feed: Salar · Geothermal · Produced Brine
Output: Mineral Concentrate + Clean Water
Driver: Low-Grade Heat · 65–85 °C
Footprint: Acres — Not Evaporation Ponds

Cooling Water Without the Watershed

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.

Feed: Seawater · Brackish · Municipal Reuse
Output: High-Purity Cooling Make-Up Water
Driver: Facility Waste Heat
Status: Platform Proven at 500 m³/Day — NELHA

Where the loop runs

Sectors Served

One forward-osmosis platform, six water problems. Every sector below has a stream too salty, too dirty, or too expensive for conventional treatment.

S-01

Data Centers

High-purity cooling make-up water from seawater, brackish, and reuse streams — driven by the facility's own waste heat.

S-02

Mining Wastewater

Concentrating tailings and process water to recover minerals and return clean water to the site.

S-03

Oil & Gas Produced Water

High-recovery thermal FO with minimal liquid discharge — proven with Petroleum Development Oman.

S-04

Municipal Reuse

Concentrating municipal waste and reuse streams past the limits of conventional membrane treatment.

S-05

Agricultural Water

Brackish and drainage water recovery for irrigation — NAWI mobile pilots across California.

S-06

Boron & Organics

Rejecting the small, hard-to-stop molecules that pass straight through reverse osmosis.
