Echivalent fier (mg/l) = 1 x continut Fe (mg/l) + 2 x continut Fe (mg/l)
Determinarea vitezei de filtrare pe baza echivalentului de fier:
            Echivalent fier              Viteza de filtrare
              < 0.2 mg/l                       20 m/h
                0.5 mg/l                       18 m/h
                1.0 mg/l                       15 m/h
                1.5 mg/l                       12 m/h
                2.0 mg/l                       10 m/h

Suprafata de filtrare necesara(mp) = Debit(mc/h) / Viteza de filtrare (m/h)
Intervalul de pH al apei: 6,2 - 8,5
Continutul clorului liber trebuie sa fie mai mic de 0,5 mg/l
Strat filtrant: 600-900mm
Volum liber min. 50% din inaltimea filtrului
Interzis continutul de ulei si polifosfati.

Regenerare: 2,5 - 3 g KMnO4 / litri strat filtrant

Dizolvare KMnO4:                                                                                          
In apa de 10oC: 30g KMnO4 / litri H2O
In apa de 22oC: 60g KMnO4 / litri H2O
