Our Specialities
Draw
Solutions
AquaDraw™
Over 300 food-grade safe thermo-responsive draw solutions that are capable of 4000psi (>260bar). Highly customizable for varied waste streams and optimizable for rare earth element recovery. Our draws lower the system energy requirements while also improving sustainability and help encourage regulatory approval. These draws are also recoverable and optimized for rare earth solvent extractions so you can reduce, reuse, and recycle.
Hypersaline Brine Processing
BrineVault™
BrineVault is the answer for rapidly deployable and highly tailored brine concentration to enable economical rare earth extractions from mining waste streams. It easily integrates with existing mining operations and electrochemical water softening to eliminate lime softening. BrineVault is optimized for near zero liquid discharge applications and is the perfect solution to minimize and extract valuable metals from brines.

Waste Heat Recovery
ThermoSnare™
Trevi’s polymeric ribbed tube heat exchangers combines high-performance engineering thermo-plastics (PEEK or PPSU) with a proven tube-in-tube design to deliver reliable heat transfer in corrosive and high-purity applications where metal exchangers fail or where acid mine drainage brines can be heated for more efficient rare earth mineral extraction.
Brine Tech Menu
Forward Osmosis & Pressurized Forward Osmosis
FO uses osmotic gradients for higher recovery and can be completely waste-heat driven, making it ideal for off-grid seawater desalination. PFO is enhanced FO for higher flux and a more compact design, applicable for myriad feed waters.
Recovery ranges from 70%-90%.
Brackish Water Reverse Osmosis
BWRO is a desalination process that removes salts and impurities from brackish water sources. This technology provides a sustainable solution for freshwater, especially in arid regions and can be used to replenish groundwater reserves.
Recovery ranges from 60%-85%.
Advanced Oxidative Processes
AOPs utilize powerful oxidants to degrade organic pollutants in water. They enhance treatment efficiency, and are effective in addressing challenging contaminants that traditional methods struggle to remove thus promoting sustainability.
Electro-Deionization Metathesis
EDM combines ion exchange and electrochemical processes to efficiently remove ions from water. This technology enhances water purification, reduces energy consumption, and minimizes chemical usage, promoting sustainable practices.
Seawater
Reverse Osmosis
SWRO is a desalination technology that uses semi-permeable membranes to remove salts and contaminants from seawater. It provides a reliable source of potable water, addressing global water scarcity challenges.
Recovery ranges from 35%-50%.
Ultrafiltration
UF is a membrane filtration process that separates particles, bacteria, and macromolecules from liquids. It effectively purifies water, enhances food and beverage processing, and supports wastewater treatment applications.
System Configurations
The aforementioned technologies can be used in many combinations to satisfy any water purification needs. Trevi offers containerized, skid-mounted, and modular systems that adapt to diverse client needs, ensuring flexibility. These energy-efficient options, including fully electric, thermal-drive, or hybrid designs, minimize environmental impact and operational costs.
Engineered for rapid deployment, these scalable systems can expand as demand increases, promoting long-term sustainability. Seamless integration with existing infrastructure enhances water treatment capabilities without extensive modifications, supporting efficient resource management. This approach addresses immediate challenges while contributing to a sustainable future by optimizing energy use and resource allocation.
Key Advantages
Our systems offer several key advantages, including high recovery rates of up to 98%, even with challenging water sources. They consume less energy than conventional reverse osmosis, enhancing efficiency. The design minimizes membrane scaling and fouling, resulting in longer membrane life.
Additionally, our technology effectively treats extremely high salinities of 200,000 mg/L TDS or less, making it suitable for diverse applications. Furthermore, flexible integration with other technologies allows for customized solutions tailored to specific client needs, ensuring optimal performance and sustainability.
Brine is a major barrier to the widespread adoption of seawater desalination and a source of issues for new industrial permitting. Trevi offers unique brine solutions to mitigate environmental impact through brine concentration, recycling, and reuse.
Recoverable resources can include lithium, nickel, salt, zinc, calcium, magnesium, and potassium. With the right extraction and treatment these can be turned into valuable commodities of their own. Our systems are custom-tailored so you can get the most out of your brine and energy source whether it's PV, geothermal, or gas turbine waste heat.
