Statii de deferizare cu granulat "Birm"

Time controlled iron remover equipment with BIRM media.                                                                                                                                                                                                                                       .

Iron equivalent (mg/l) = 1 x Fe index (mg/l) + 2 x Mn index (mg/l)

Determination of the Filtration velocity according to iron equivalent:

              Iron equivalent                              Filtration velocity

              <0.2 mg/l                                       18 m/h

                0.5 mg/l                                       15 m/h

                1.0 mg/l                                       12 m/h

                1.5 mg/l                                       10 m/h

                2.0 mg/l                                         8 m/h

                3.0 mg/l                                         6 m/h

Required filtering surface (m2) = Flow rate (m3/h) / Filtration velocity (m/h)

Birm capacity: 1,4gFe/l

Backwash: 25-30m/h

Bed depth: 75-90cm

Water pH-range: 6,8 – 9,0

The solve oxigene index has to be 15% of the iron index.

The free chlorid index has to be lower than 0,5 mg/l.

The sulphurhydrogene has to be removed before the filter.
