Abstract

La invención se refiere a un dispositivo de filtración de agua que comprende un piso (2) sobre el cual se proporciona una primara capa (5) de un primer medio (A) que contiene granos de alta densidad con un diámetro medio Da, y una segunda capa (6) de un segundo medio (B) que contiene granos que tienen un diámetro medio Db y una densidad menor a la del primer medio (A), estando Db más alto que Da. En la porción superior se proporciona una entrada (7) para el agua que se va a filtrar y bajo la segunda capa se proporciona una salida (8) para el agua filtrada. El diámetro medio Db es tal que las partículas del segundo medio (B) están separadas por espacios que tienen un tamaño que resulta suficiente para permitir el flujo por gravedad de las partículas del primer medio (A). El segundo medio (B) tiene una velocidad de fluidización que es mayor que la del primer medio (A), y en el piso (2) se proporcionan los medios (I) para inyectar un fluido limpiador, para inyectar un fluido a una velocidad tal que el segundo medio (B) se expande por un valor de entre 1 y 10%.
