Abstract

E' descritto un filtro (1) per la separazione solido-liquido di fanghi ed altri fluidi derivanti da processi di lavorazione industriali, il quale presenta una notevole compattezza che lo rende particolarmente vantaggioso rispetto ad altri analoghi filtri della tecnica nota. Nella sua forma preferita, il filtro (1) comprende un contenitore (5) esterno dotato di una parete laterale (5c) con fori (8), all'interno del quale è alloggiato un corpo filtrante (10); quest'ultimo, a sua volta, comprende un sacco (12) di tessuto filtrante avvolto da una rete (15) di drenaggio, ed una membrana (25) deformabile. Più in particolare, tale membrana definisce un volume (V) all'interno del contenitore (5), chiuso e di dimensioni variabili in relazione con le deformazioni subite dalla membrana (25) a causa di acqua che viene pompata all'interno del volume (V) da mezzi (30) convenzionali. Secondo una forma preferita, la membrana (25) è formata da un tubo flessibile ripiegato ad "U" e chiuso ad una estremità (25a).
