ASTERIx-CAESar project partner Apria is responsible for the design and development of the reverse osmosis pilot plant. The below final design allows for combining the project’s power plant concept with water desalination. Throughout the process, close collaboration with CIEMAT-PSA has been valuable in refining key aspects of the design.
- The prototype is designed to treat 1 m3/h of brackish water, and it’s able to achieve high recovery rates.
- The pressure required to drive the RO is provided by a Gas-Liquid-Pressure-Exchanger (GL-PX), which uses pneumatic air from the CAES system.
- This theoretically allows the RO system to be able to work 24/7 using the renewable energy supply from CAES pressure energy storage, making it independent from the electricity grid.
- The prototype is also designed to avoid brine discharge and reduce consumption of water resources, reducing the environmental footprint of the RO desalination validation within the framework of the ASTERIx-CAESar project.
