Eden Tech Licenses NAWI-Supported Aqueous Separation Technology

Eden Tech recently licensed two aqueous separation technologies developed by researchers at Idaho National Laboratory (INL), one of which is supported by NAWI. NAWI Alliance member and INL researcher, Aaron Wilson, is leading the vital NAWI project, which pioneers the use of dimethyl ether (DME) as a solvent to concentrate brines for zero-liquid discharge (ZLD).

The second technology, which was supported by DOE’s Critical Materials Institute, also leverages a condensable gas solvent to drive low-cost dewatering and selective precipitation of target products from aqueous feed streams. Eden plans to deploy both technologies in solution mining applications related to the Circular Water project in Saudi Arabia, and is marketing the technology under the CircularH2O brand.

Wilson is the principal investigator of NAWI task Solvent-Driven Zero Liquid Discharge for Production of Synthetic Gypsum. NAWI’s goal with this project is to ultimately advance DME-Driven ZLD desalination for treating water associated with brine management. By addressing the challenge of fugitive solvent loss, the DME-based process can bring significant improvements to brine concentration, including increased water recovery, reduced capital and energy costs, reduced land requirements, and reduced environmental impacts.
