Saltworks Deploys Two FusionRO Plants for Lithium and Water Reuse Applications

August 5th, 2025

Saltworks Technologies (“Saltworks”) has successfully deployed two FusionRO plants to international clients, marking another milestone in advancing ultra-high membrane brine concentration (MBC) technologies.

FusionRO, a form of low-salinity rejection reverse osmosis (LSRRO), achieves a brine concentration of sodium chloride exceeding 220,000 mg/L at 50% lower capital expenditure (CapEx) and operating expenditure (OpEx) than evaporators.

One plant was sold to a dominant lithium refiner and is concentrating lithium before conversion at a lower cost and energy than evaporators. The second plant was shipped to an industrial site to treat and reuse water while producing a minimal liquid discharge (MLD) brine. Both modular plants were rapidly installed and are operating as expected.

FusionRO hybridizes ultra-high-pressure reverse osmosis (UHP-RO) with UHP nanofiltration to concentrate brines 175% higher than conventional seawater RO.

Unlike lower-pressure RO systems, FusionRO requires half the number of high-pressure stages owing to its ultra-high pressure cascading loop design. The system features intelligent membrane monitoring, protection, and preservation controls to maintain membrane health, delivering significant energy and cost savings compared to evaporators on suitable fluids.

All Saltworks’ full-scale and pilot solutions are modular, factory-built, and fully commissioned before shipping. Our plug-and-play design reduces installation time, cost, and complexity in the field compared to conventional stick-built options.
