Title
(ES) PROCESO PARA ELIMINAR ESPECIES DE NITROGENO DE UN SISTEMA DE RECIRCULACION DE AGUA DULCE (RAS), Y PROCESO PARA ELIMINAR AMONIACO DE SISTEMA DE RECIRCULACION DE AGUA SALADA, DE MANERA DE MANTENER CONCENTRACION DE NITROGENO AMONIACAL TOTAL MENOR A 50MGN/L, QUE COMPRENDE MANTENER EL PH DEL AGUA EN EL RAS BAJO 7,5.
Abstract
(ES)

UN PROCESO PARA ELIMINAR ESPECIES DE NITRÓGENO DE UN SISTEMA DE RECIRCULACIÓN DE AGUA (RAS) DULCE MIENTRAS SE MANTIENE UNA CONCENTRACIÓN DE NITRÓGENO AMONIACAL TOTAL (TAN) DE¡ AGUA EN DICHO SISTEMA ENTRE 15 Y 50 MGN/L, QUE CONTEMPLA LOS PASOS DE: A. MANTENCIÓN DE¡ PH DE¡ AGUA EN EL RAS BAJO UN PH DE 7,5 MEDIANTE LA ADICIÓN DE UN ÁCIDO; B. EXTRACCIÓN DE UNA PARTE DE¡ AGUA DE¡ RAS; C. PASO DE LA PARTE DE AGUA DE¡ RAS POR UNA RESMA DE INTERCAMBIO DE IONES DE MANERA DE ELIMINAR LOS IONES NH4 ; D. REGENERACIÓN DE LA RESMA DE INTERCAMBIO DE IONES ENRIQUECIDA CON NH4 OBTENIDA EN EL PASO (C) USANDO UNA SOLUCIÓN QUE COMPRENDE ALTAS CONCENTRACIONES DE CATIONES DE INTERCAMBIO Y CLORURO COMO EL CONTRA ANIÓN A CONCENTRACIONES SOBRE 50 G CIIL; E. CONVERSIÓN DE IONES NH4 ACUMULADOS EN LA SALMERA OBTENIDA DURANTE EL PASO (D) A NITRÓGENO GASEOSO (N2) GENERANDO ESPECIES DE CLORO ACTIVO CAPACES DE REALIZAR LA OXIDACIÓN DE AMONÍACO EN GAS NITRÓGENO ELECTROQUÍMICAMENTE; Y F. OPCIONALMENTE, REPETICIÓN DE LOS PASOS (A) A (E) DE MANERA CONTINUA, SEGÚN SEA NECESARIO.
