PERFECCIONAMIENTOS EN EL PROCEDIMIENTO DE ELECTRODIALISIS MEDIANTE EL TRATAMIENTO DEL AGUA DE ALIMENTACION POR RESINASPERMUTADORAS DE IONES.

摘要

A process for the desalination of salt water employing separate sodium and hydrogen form cation exchange resins to soften, to dealkalize and to partially deionize the said water prior to substantial demineralization by electrodialysis. The salt-concentrated waste stream from the electrodialysis cell may be employed to regenerate the sodium-form exchange resin that becomes exhausted during the softening step.
