Abstract

EL PROCEDIMIENTO SE BASA EN UN PROCEDIMIENTO DE ELECTRODIALISIS. CON MEMBRANAS APROPIADAS SE OBTIENE UNA MIGRACION DEFINIDA DE LOS IONES NO3- Y CON ELLO UNA SEPARACION SELECTIVA DE LOS NITRTATOS NOCIVOS. SE DESCRIBEN MEMBRANAS INTERCAMBIADORAS DE ANIONES CON UNA SELECTIVIDAD >1 PARA EL TRANSPORTE DE CLORUROS FRENTE AL DE SULFATOS Y MEMBRANAS INTERCAMBIADORAS DE CATIONES CON UNA SELECTIVIDAD >1 PARA EL TRANSPORTE DE NA+ FRENTE A CA2+. LAS MEMBRANAS SON DE MATERIAL PLASTICO CON TRATAMIENTO SUPERFICIAL.
