Abstract

E' descritta una sezione di filtrazione terziaria per affinamento acque reflue da disporsi in particolare a valle di un impianto di depurazione, comprendente una pluralità di pannelli filtranti (13) disposti in file parallele (12) all'interno di una vasca di trattamento (11), sulla quale è previsto un carroponte a va e vieni (14) portante un sistema di controlavaggio per la pulizia dei filtri e per l'aspirazione dal fondo della vasca (11), nonché un sistema di sollevamento (16) per lo sfilamento dei pannelli (13) che sono montati su tubi verticali forati (21), solidali ad una tubazione di fondo (20) che collega i pannelli di ciascuna fila e attraverso la quale vengono evacuate le acque filtrate.
