IRON-REMOVAL / MANGANESE-REMOVAL 

Iron-Removal:

Removal of iron from ground water and raw water, applied primarily as pre-filtration before the water is led to an ion-exchange unit.

The iron is oxidized through oxygen by way of adding oxidation substances.

After that the iron-oxide-flakes, which have been formed during this process, are cleaned by a gravel or multi-layer-filter.

Manganese-Removal:

Manganese is very often contained in ground or well water.

It is oxidized through the addition of oxygen.

The flakes forming during this procedure are cleaned through a gravel filter or a special material for filtration, which ensures a biological support through bacteria.
