Abstract

LA INVENCION SE REFIERE A UN METODO PARA DEPURAR LIQUIDOS CON PARTICULAS SOLIDAS EN SUSPENSION, P. EJ., AGUAS RESIDUALES O AGUA POTABLE, EN EL CUAL EL LIQUIDO ES CONDUCIDO A TRAVES DE UN RECIPIENTE (1) QUE CONTIENE PARTICULAS FILTRANTES SUELTAS. PARA EVITAR QUE ESTAS PARTICULAS FILTRANTES SE ESCAPEN POR LA SALIDA (3) DEL RECIPIENTE, SE INCLUYE UN DISPOSITIVO DE RETENCION (8). A PARTIR DE UNA CIERTA CARGA SUPERFICIAL DEL LIQUIDO SE CREA EN UNA ZONA DE BAJO FLUJO (6) SITUADA ANTES DEL DISPOSITIVO DE RETENCION (8) UNA CAPA DE FILTRADO ESTACIONARIA DE BUENA PERMEABILIDAD QUE RETIENE LAS PARTICULAS SOLIDAS CON UNA ELEVADA CAPACIDAD DE FILTRADO SIN QUE ELLO AFECTE AL DISPOSITIVO DE RETENCION (8). EN LA DIRECCION DEL FLUJO DEL LIQUIDO Y ANTES DE ESTA ZONA DE BAJO FLUJO (6) SE CREA UNA ZONA DE TURBULENCIA (5) QUE TAMBIEN PUEDE SER UTILIZADA COMO BIORREACTOR. PARA REGENERAR LA CAPA DE FILTRADO SE CIERRAN LA ENTRADA (2) Y LA SALIDA DEL LIQUIDO. DE ESTA FORMA LA CAPA ESTACIONARIA DE FILTRADO SE SEPARAPOR SI MISMA Y SE FLUIDIZA EN LA ZONA DE TURBULENCIA (5) EN PARTICULAS INDIVIDUALES, LIBERANDO LAS PARTICULAS SOLIDAS ALMACENADAS. UNA VEZ RETIRADA LA SUSPENSION ENRIQUECIDA CON PARTICULAS SOLIDAS, SE VUELVE A LLENAR EL RECIPIENTE (1) CON LIQUIDO Y CUANDO SE ALCANZA UNA CIERTA CARGA SUPERFICIAL SE VUELVE A FORMAR UNA NUEVA CAPA DE FILTRADO.
