Abstract

EN UN PROCEDIMIENTO PARA LA DESALACION PARCIAL DEL AGUA, EN PARTICULAR DE AGUA POTABLE, CON UNA MEZCLA DE INTERCAMBIADORES DE CATIONES DEBILMENTE ACIDOS E INTERCAMBIADORES DE ANIONES FUERTEMENTE BASICOS SE REGENERAN LOS INTERCAMBIADORES CARGADOS DE IONES MEDIANTE AGUA QUE CONTIENE CO 2 OPCIONALMENTE CON ADICION DE CACO 3 , CACO 3 /MGO, CA(OH) 2 Y OT ROS. SIMULTANEAMENTE SE REDUCEN CON LA DESALACION PARCIAL LOS COMPUESTOS DE CARBONO ORGANICOS QUE HAY PRESENTES EN EL AGUA, REGENERANDO LOS INTERCAMBIADORES DE IONES CARGADOS DE MANERA DISCONTINUA CON HCL, NACL, NAOH O CON UNA MEZCLA FORMADA POR NACL Y NAOH.
