    Iron removal plants can be based on different filtration media, depending on the iron and manganese concentration, the oxygen level, CO2 content and hardness of the water.

    Plant principle:
    First, air is injected in order to oxidize the iron. The oxidized iron will then precipitate on a sand filter. An MnO2 layer in the sand bed will catalyze the oxidation of residual iron. Backwash will be done by water and by air.

    Filtration media choice are:
    - Sand + MnO2 for high iron concentrations
    - Calcite for acidic waters
    - Birm
    - Greensand

    -Katalox Light


    Other oxidation chemicals can be used for highly contaminated waters
    - Ozone
    - Chlorine
    - Chlorine dioxide
    These chemicals also have a biocide effect but might interact with other component.

    Typical deironing plant includes:

    - Feed / backwash pump
    - Pressure vessel filled with deironing media
    - Valves, fittings and instrumentation

    Plant general specifications may vary with WA reports,customized solutions are available
