Abstract
Placa de filtración rígida para deshidratar lodos, caracterizada porque comprende al menos una primera capa y una segunda capa, constituyendo la primera capa un elemento plano filtrante constituido esencialmente por partículas irregulares y constituyendo la segunda capa un soporte particulado para la primera capa, siendo las partículas de la primera capa de un material o materiales cuya dureza en la escala de Moh es al menos de 7 y que están aglomeradas entre sí mediante un aglutinante adhesivo, siendo al menos la mayoría de las partículas de al menos dos tamaños cuyo diámetro medio está comprendido substancialmente entre 0, 01 cm y 0, 23 cm, teniendo la segunda capa partículas que son mayores que las partículas más grandes de la primera capa y estando las partículas de la segunda aglomeradas entre sí y con la superficie inferior de la primera capa por un aglutinante adhesivo.
