WATER TREATMENT

2019-1-4 · When iron is not present in the row water feed, its presence in the boiler or cooling system indicates active corrosion, a more serious problem than its presence in scale in which it appears by occlusion. Rust, the reddish form, is fully oxidized. More often, in a boiler with limited oxygen, it is in the reduced or black form (Fe3O4).
