Abstract

Procedimiento a instalación para filtrar agua de una corriente de modo que se reduzca al mínima la eliminación de vida acuática y detritos de la corriente, procedimiento caracterizado porque comprende las etapas de guiar una corriente de agua para que fluya en una dirección predeterminada dentro de un canal, tomar una cantidad de agua para que diverja lateralmente de la corriente del canal a una boca de admisión de agua, filtrar la cantidad divergente de agua, con una superficie cribadora de un colador de cinta sinfín, someter a rotación el cribador de cinta sinfín para desplazar la superficie cribadora desde un lugar a través del cual fluye el agua divergente hasta un lugar adyacente el flujo de agua divergente, y dirigir una corriente de retrolavado o contracorriente a través de la superficie cribadora en un lugar adyacente en dirección a la corriente de agua que fluye en el canal y a una altura situada por debajo de la superficie de la corriente, por lo que el material retenido sobre lasuperficie cribadora se puede desalojar por la corriente de retrolavado y verse obligado a retroceder de la superficie cribadora pasando a la corriente de agua que fluye en el canal para ser arrastrado por la misma.
