Abstract

Filtre dans lequel une matière filtrante granulaire est en vrac sur un plateau à tuyères La filtration de liquides souillés a pour conséquence des agglutinations des souillures que le rinçage à contre-courant aux vitesses usuelles ne permet pas d'évacuer. La rive du plateau 11 est conformée en conséquence de manière à augmenter la section de circulation. Le débit d'eau de rinçage augmente ainsi le long de la rive en élevant la vitesse locale de circulation. Cette augmentation peut s'obtenir par une élévation du nombre des tuyeres par unité de surface et/ou par une augmentation de la section de passage par les tuyères se trouvant dans la région de la rive. Application notamment à l'épuration des eaux usées.
