Every desalination technology fights osmotic pressure. Trevi's platform recruits it — then regenerates with cheap heat instead of expensive electricity.
Impaired water and a highly concentrated draw solution meet across a semi-permeable membrane.
Natural osmotic pressure pulls pure water across the membrane under low pressure — below 60 psi, no high-pressure pumps.
Low-grade heat triggers a phase separation, splitting the draw solute cleanly out of the fresh water.
The concentrated draw solute returns to the membrane in a closed loop — continuously, with nothing consumed.
Product water passes a nano-filter to meet WHO, NSF, and international drinking-water standards.
For streams saltier than the draw itself: Pressurized Forward Osmosis (PFO) — a hybrid of FO and RO that treats hypersaline brines at far lower hydraulic pressure than conventional reverse osmosis.
Trevi's proprietary retrograde thermolytic draw solution — the engine of the loop. High osmotic pressure to desalt the hardest feeds, phase-separating on low-grade heat, and FDA-approved as food-safe, biodegradable, and non-toxic in aquatic environments.
Brine concentration and resource recovery. Pressurized forward osmosis (PFO) keeps concentrating where reverse osmosis stalls — toward zero liquid discharge, holding lithium, rare earths, and other minerals in a recoverable concentrate.
Low-grade heat capture that drives draw regeneration — industrial waste heat, concentrated solar thermal, or geothermal sources conventional desalination can't use. Roughly 80% less energy than conventional systems, with a path to net-zero operation.
Feed water meets the FO membrane; clean water crosses into the AquaDraw™ solution while salts, minerals, and contaminants stay behind and concentrate. Because the membrane is never forced, fouling and pretreatment demands collapse — and the concentrate becomes the product, not the disposal problem.
Critical minerals, water security, and data center growth converge on one platform — secure the supply before it's scarce.
