Abstract

Un filtro de flujo radial (120) empleando particulas granuladas no ligadas (56) para filtrar impurezas de un afluente. y que se puede relavar por medio de la fluidificacion de las particulas granuladas (56) para liberar las impurezas de estas. Durante la operacion de relavado, un liquido de relavado aplica una fuerza de arrastre dirigida hacia arriba sobre una porcion superior de las particulas granuladas (56) para levantar las mismas hacia una camara de relavado (62) para la fluidificacion. Una vez que la porcion superior de las particulas granuladas (56) de el yacimiento de filtracion es fluidificada, el liquido de relavado aplica una fuerza hacia arriba en la porcion subsiguiente de el yacimiento granular, asi fluidificando las particulas granulosas (56) en la camara de relavado (62). Secciones subsiguientes de el yacimiento granular son fluidificadas en una manera similar para asi completamente limpiar las particulas granuladas (56). Despues de la operacion de relavado, las particulas granuladas (56) caen de regreso a la camara de filtracion (156) y forman un yacimiento de filtracion para llevar a cabo la operacion de filtracion.
