The National Science Foundation awarded Waterus LLC a $1.234 million cooperative agreement on August 1, 2026, under the NSF Technology, Innovation, and Partnerships program (CFDA 47.084) to develop a continuous, salt-free water softening system using a scalable redox-mediated electrochemical architecture. The project advances a novel electrochemical approach that replaces conventional salt-based ion exchange with a continuous, electricity-driven process to selectively remove hardness ions without chemical regenerants. Phase II research and development scales the concept from laboratory validation to a household-capable system operating under realistic residential flow rates and pressures. Work includes iterative design, fabrication, and testing of multi-stack electrochemical cells to improve mechanical robustness and sealing reliability; advanced modeling and experimental validation to optimize flow distribution, electrical performance, and material durability; full-scale prototype integration and evaluation through laboratory testing and extended residential field trials; and design for manufacturability, long-term operational stability, and safe handling of mineral byproducts. The system uses minimal electricity, requires almost no maintenance, and eliminates the need for harsh chemical additives. Performance occurs in Irmo, South Carolina, with a period of performance from August 1, 2026, through July 31, 2028. The $1.234 million represents the obligated amount under the cooperative agreement.
