Cetos Water is a Columbia University spinout building the infrastructure layer to turn the world’s most concentrated industrial wastewater into clean water and critical minerals — helping heavy industry reduce disposal, unlock new water supply, and keep production running in water-constrained environments. Our core breakthrough is a membrane-less, non-evaporative extraction process that treats hypersaline brines conventional systems can't handle, including streams far beyond the salinity limits of membrane systems. By avoiding boiling corrosive brines, we deliver a solution that is 70% more energy efficient and 50% more capital efficient than state-of-the-art technologies.
Our customer acquisition strategy is focused on production-critical industries where water is becoming a direct operational and permitting constraint, including oil & gas, mining, power generation, and data centers. We are partnering with operators through paid pilots and testing engagements, using early technical validation, rising disposal costs, and tightening regulatory pressure to drive commercial adoption.
