Abstract
Impianto per depurazione di acque reflue industriali essenzialmente composto da tre stadi modulari:uno stadio (16) di prefiltrazione o microfiltrazione, uno stadio(30) di ultrafiltrazione effettuata con membrane di poliammide ed uno stadio (62) di osmosi inversa con membrane di polisolfone in grado di lasciar passare solo acqua pura al 100%. Viene descritto anche un metodo per far funzionare l'impianto che utilizza vantaggiosamente acque estratte da punti intermedi dell'impianto per provvedere lavaggi e rigenerazioni degli stadi di filtrazione e di osmosi inversa.
