Abstract

LA INVENCIÓN SE REFIERE A UN DISPOSITIVO DE ELECTRODESIONIZACIÓN QUE COMPRENDE UN COMPARTIMIENTO DE REDUCCIÓN CONECTADO DE FORMA FLUIDA A UNA FUENTE DE AGUA QUE CONTIENE SÓLIDOS DISUELTOS. ESTE COMPARTIMIENTO ESTÁ CONECTADO A TRAVÉS DE UNA MEMBRANA CATIÓNICA SELECTIVA A UN COMPARTIMIENTO DE CONCENTRACIÓN, EL QUE ESTÁ CONECTADO EN FORMA FLUIDA EN SENTIDO DESCENDENTE DESDE UNA FUENTE DE UN PRIMER LÍQUIDO ACUOSO QUE TIENE UNA CONCENTRACIÓN DE SÓLIDOS DISUELTOS. ESTE COMPARTIMIENTO A SU VEZ ESTÁ COMUNICADO CON UN SEGUNDO COMPARTIMIENTO DE REDUCCIÓN CONECTADO DESDE UNA FUENTE DE LÍQUIDO ACUOSO, QUE POSEE UNA CONCENTRACIÓN DE SÓLIDOS MAYOR AL DE¡ COMPARTIMIENTO DE CONCENTRACIÓN; UN SISTEMA DE BAJO CONSUMO ENERGÉTICO Y EL CORRESPONDIENTE MÉTODO ADECUADOS PARA DESALINIZAR AGUA DE MAR O SALOBRE, LOS CUALES COMPRENDEN ETAPAS DE ELECTRODIÁLISIS Y ELECTRODESIONIZADO, QUE TIENEN PARES DE MEDIAS CELDAS DE POTENCIAL BASADAS EN LA CONCENTRACIÓN.THE INVENTION REFERS TO AN ELECTRODESSIONIZATION DEVICE INCLUDING A REDUCTION COMPARTMENT FLUIDLY CONNECTED TO A SOURCE OF WATER CONTAINING DISSOLVED SOLIDS. THIS COMPARTMENT IS CONNECTED THROUGH A SELECTIVE CATIONIC MEMBRANE TO A CONCENTRATION COMPARTMENT, WHICH IS CONNECTED IN A FLUID WAY DOWNWARDS FROM A SOURCE OF A FIRST AQUEOUS LIQUID THAT HAS A CONCENTRATION OF SOLIDS. THIS COMPARTMENT IN TURN IS COMMUNICATED WITH A SECOND REDUCTION COMPARTMENT CONNECTED FROM A SOURCE OF AQUEOUS LIQUID, WHICH HAS A CONCENTRATION OF SOLIDS GREATER THAN THE CONCENTRATION COMPARTMENT; A LOW ENERGY CONSUMPTION SYSTEM AND THE CORRESPONDING APPROPRIATE METHODS TO DESALINATE SEA OR BRACKET WATER, WHICH INCLUDE ELECTRODIALYSIS AND ELECTRODESSIONIZED STAGES, WHICH HAVE PAIRS OF HALF CELLS OF CONCENTRATION BASED ON CONCENTRATION.
