Abstract

DICHO PROCESO COMPRENDE EL TRATAMIENTO DE UNA CORRIENTE DE AGUA DE ALIMENTO ACONDICIONADA CON ANTI-ESCORIANTE PROVENIENTE DE UNA FUENTE QUE CUENTA CON UN SISTEMA DE MEMBRANA POR OSMOSIS INVERSA PARA PRODUCIR UNA CORRIENTE PERMEADA DE AGUA PURIFICADA Y UNA CORRIENTE DE PURGA QUE CONTIENE LOS IONES RETENIDOS O RECHAZADOS Y MATERIA ORGANICA. LA CORRIENTE DE PURGA LUEGO ES TRATADA PARA RECONOCER ESPECIES DISUELTAS Y SUSPENDIDAS. LA CORRIENTE DE PURGA ES DIRIGIDA A UN PROCESO DE DESATURACION/CLARIFICACION. UN PROCESO QUE TIENE PREFERENCIA INCLUYE UN REACTOR DE TANQUE AGITADO CONSTANTE DONDE SE AGREGA AGENTE DE CO-PRECIPITACION, SEGUIDO POR UN CLARIFICADOR. EL AGUA RECICLADA DEL REBOSE DEL CLARIFICADOR ES MEZCLADA CON LA CORRIENTE DEL AGUA DE ALIMENTACION. LOS SOLIDOS REMOVIDOS SON RECOLECTADOS COMO UN LODO O UNA SUSPENSION, Y DISPUESTOS DE MANERA ACORDE CON LAS REGULACIONES APLICABLES
