- The iron content of the water can be as high as 15 mg/litre as Ferrous Carbonate.
- This is several times higher than the acceptable concentration of 0.2 to 0.3 mg/litre in potable water. Excess iron in water is undesirable for human consumption.
- Ferrous iron 1s soluble in water at any pH
- At a pH less of about 3.5, ferric iron is soluble in water. But, if the pH is higher than 3.5, the ferric iron becomes insoluble and precipitates (form a solid) as an orange/yellow compound.
NICHEM offers an Iron Catalyst to facilitate iron removal (both ferrous & ferric forms) from drinking water.
