Trevi Systems is the recipient of three grants, awarded for the development of low energy desalination processes. Trevi intends to use these opportunities to demonstrate scalability and ensure water quality of its forward osmosis process.
Orange County, CA, USA
Trevi was awarded a California Energy Commission PIR Grant of $1.7 million to pilot a system to desalinate reverse osmosis concentrate at Orange County Water District (OCWD). OCWD is a world leader in waste water reuse since the 1970s. The old Water Factory 21 was recently replaced by the Ground Water Replenishment System, a 100 mgd facility that treats secondary wastewater effluent with microfiltration, reverse osmosis then advanced oxidation before pumping the clean water to the Talbert barrier and to several recharge basins.
Port Huenema, CA, USA
The system has completed its laboratory trial period, demonstrating energy savings and capital costs. Trevi has now completed field trials at the US Navy NFESC facility in Port Hueneme. These trials validated energy savings, monitored the long term water quality and verified that thermal operating parameters of the FO system remain within acceptable ranges.
Tiburon, CA, USA
The Romberg Tiburon Center offers opportunities for SFSU undergraduate and graduate students to gain field experience, laboratory training, and practice skills in a variety of environmental research areas. Courses are offered at the center through the departments of biology, chemistry, geography and geosciences.
Trevi installed a 10m3/day System at the Romberg Facility in Tiburon in October 2013. The Romberg offered access to untreated seawater, enabling Trevi to determine the bio- fouling potential of the process as well as identify the best pre-treatment for seawater FO systems.
Abu Dhabi, U.A.E.
Masdar awarded four companies – Abengoa, Degrémont, Sidem/Veolia and Trevi Systems – with contracts to each start the construction of a desalination plant as part of Masdar’s pilot project in Abu Dhabi. First announced in January 2013, the project aims to develop, demonstrate and assess energy-efficient seawater desalination technologies efficient enough to be powered by renewable energy. The pilot program sets the ground work for the potential implementation of domestic commercial scale seawater desalination plants powered by renewable energy.
Kuwait City, Kuwait
Trevi has completed the construction of a 10 m3/day pilot system and will be building an additional 5 systems to be installed within the next two years. The intent of the pilot is to demonstrate the energy saving and scaling potential in the Gulf region. Results from this trial will be added to this page.
Kailua-Kona, Hawaii, USA
Trevi has commenced construction of its 4th generation Forward Osmosis plant to be built in Kona, Hawaii at the NELHA campus. The system will use a low temperature CSP array (repurposed from electricity production to thermal energy), including thermal energy storage using volcanic rock and/or water. The FO plant will run at high recovery (up to 60%) and produce 130,000 gallons per day (500m3/day) of potable water. An off-take customer has been selected that will use the water for algae production. The water will be evaluated for potable use with plans to increase the capacity to over 6000m3/day at the same site once the semi-commercial plant is operational. The plant is expected to start its commissioning phase in Q1, 2020 and when fully operational, it will use only renewable energy for operation and emit no CO2 while desalinating seawater. The high recovery also points to its use as a technology for zero liquid discharge and longer term brine concentration for mineral recovery. These technologies will be evaluated during the test period.
We will partner with existing desalination companies to promote the widespread adoption of the technology through licensing and joint venture partnerships. Trevi believes that this is the best use of the technology in order for it to have a global impact in reducing hunger and water shortages in the world.We have collaborated with many leaders in the water industry in order to bring our technology to market. If you have expertise in the water sector, please consider partnering with us.
