The National Institute of Environmental Health Sciences (NIEHS) awarded a $138,738 Project Grant under the Superfund Hazardous Substances Basic Research and Education program (CFDA 93.143) to Chemfinity Technologies, Inc., a minority-owned small disadvantaged business. The project aims to develop and demonstrate the feasibility of Chemfinity's patented membrane-based Ion-Capture Electrodialysis (IC-ED) technology for the remediation of acid mine drainage (AMD). The key objectives are to optimize the fabrication of Chemfinity's metal-harvesting membranes for pilot-scale production, incorporate these materials into a continuous lab-scale IC-ED system, and test the system's performance in treating both ideal and synthetic/real AMD solutions. The project targets achieving at least 90% copper capture and desalination rates at a minimum flow rate of 1 liter per day, while also demonstrating the reusability of the membranes through in-situ and ex-situ regeneration methods. Successful completion of these aims will validate the feasibility of Chemfinity's technology for AMD treatment applications and support their long-term goals of mitigating the environmental impact of this mining byproduct.
