Recovery of Regenerant Electrolyte

Recovery of Regenerant Electrolyte
Inventors: Tom Davis
Patent No. 9,776,137

This patent addresses the current problem of recycling spent waste from salt regeneration. While utilizing electrodialysis to reduce the amount of discarded salt, the device helps treatment of aqueous solutions. Hard water is softened with minimal addition of salt, thus reducing the amount of discarded waste.

Methods, systems and compositions for recovery of regenerant ions from spent regenerant solution by utilization of electrodialysis are provided. For example, in certain aspects methods for separating spent regenerant using an electrodialysis system comprising selective membranes are described. Furthermore, the invention provides methods for treating a friable solid ion-removal material to prevent fragmentation during regeneration.
