The National Science Foundation (NSF) awarded a $250,000 Project Grant under the Engineering program (CFDA 47.041) to Arizona State University's Division (doing business as Orspa) to explore the role of ion dehydration in regulating transport and selectivity of monovalent ions in polyamide nanofiltration membranes. The 3-year project will investigate the fundamental mechanisms governing ion separation in nanofiltration membranes, with the goal of advancing separation technologies for water purification, desalination, and resource recovery. The research effort includes computational modeling, lab experimentation, and membrane fabrication to understand how membrane surface properties impact ion dehydration and selectivity. The project will also incorporate outreach activities to enhance STEM education and public awareness around sustainable water and resource management. No subawards are planned under this grant.
