Trevi Systems develops sustainable water-treatment technologies centered on forward osmosis desalination and brine concentration. The company prioritizes using low- and renewable-energy inputs to drive treatment and to recover value from saline streams. Its work spans seawater and brackish groundwater, as well as industrial wastewater, including mining-related effluents. Based in Rohnert Park, California, the firm operates in the climate technology product manufacturing space as a small to mid-sized organization. In 2025, Trevi announced an integration with MediSun to combine forward osmosis with MediSun's technologies, a move described as reducing energy demand and increasing value recovery from brine.
