At Trevi Systems Japan, we are committed to pioneering sustainable water solutions that address some of the most pressing challenges facing industries and communities today. Our advanced Forward Osmosis (FO) technology enables highly efficient water treatment and resource recovery, setting new standards for environmental responsibility and operational performance. By leveraging waste heat through Thermal FO, we deliver innovative approaches to green water desalination and resource recovery with Zero Liquid Discharge (ZLD) and Minimal Liquid Discharge (MLD) systems. Our systems help industries minimize wastewater, recycle valuable resources, valorize lower grade waste heat, and reduce their environmental footprints. We aim to partner with Japanese industry leaders, research institutions, and government agencies to accelerate the adoption of next-generation water recycling and reuse systems. Through collaboration and compliance with Japan’s rigorous standards, we strive to contribute to the nation’s Green Transformation (GX) and global efforts toward a circular economy. Thank you for your continued trust and support as we work together to make clean water and resource recovery a reality for all.

Trevi Systems Japan G.K. is the Japanese subsidiary of Trevi Systems Inc., a U.S. based developer of Forward Osmosis technology powered by renewable energy.
​
Our Technology
Trevi's FO system uses natural osmotic pressure to separate freshwater from seawater or wastewater, reducing energy consumption by up to 80% compared to traditional reverse osmosis.
​
Technical Advantages:
- Higher waste capacity (TDS allowance)
- High Osmotic Pressure (4000psi)
- Less membrane fouling and scaling
- Off-Grid Capable & Rapidly Deployable Systems


Why Forward Osmosis?
80% Lower Energy
FO systems are very low energy as well as ultra-low pressure. That means a safer working environment and lower CapEx & OpEx.
Renewable Ready
Trevi's patented draw solutions are food grade safe and activated by low grade heat like solar thermal, geothermal, or industrial waste heat.
Up To 98% H20 Recovery
Trevi's recent inland brackish water recovery system demonstrated up to 98% recovery acroass multiple sites and varying feed sources.
