conforme alla norma UNI EN 858-1
con Filtro a Coalescenza
Caratteristiche e Funzionamento
L'Impianto di Prima Pioggia in continuo è in realtà un sistema che viene installato per il trattamento delle acque di dilavamento, chiamate così perchè dilavando il materiale immagazzinato sull'area di rifermento, queste continuano a produrre un refluo da depurare anche successivamente alla prima parte dell'evento meteorico. In questo tipo di impianto non è presente il pozzetto scolmatore pertanto le acque entrando in vasca vengono immediatamente trattate. Nel primo comparto avviene la dissabbiatura-separazione fanghi, successivamente le acque vengono convogliate nel secondo scomparto dove avviene la flottazione gravimetrica degli oli e nel comparto finale le restanti micro particelle vengono intrappolate grazie all'effetto per coalescenza dei filtri installati.
