Iron catalyst
Water Purification Chemicals
Iron catalyst is a high surface area catalytic media which is used to remove excess concentration of iron from drinking water. It is designed to remove both ferrous & ferric forms of iron.
Where is it used?
It is used in community or industrial water filters where water is heavily contaminated with iron salts.
How does it work?
Iron removal consists of a 3-stage media system – Iron catalyst, pH Correction & Sediment Filtration. Ferrous iron is soluble in water at any pH. Ferric iron is soluble at a lower pH of about 3.5. Thus, at higher pH, the ferric form becomes insoluble & precipitates.
When iron contaminated is passed through Iron Catalyst, it oxidizes the ferrous form of iron to ferric form in presence of dissolved oxygen in water. This increases the pH of water resulting in formation of ferric hydroxide precipitate. It appears like a dark brown color powder which is then filtered using sediment filter.
What are its unique features?
- Uses Advanced Catalytic Technology (ACT) to remove iron from water
- Removes both ferrous & ferric forms of ions
- Works at minimum replacement cost
- Ecologically safe, Non-toxic
- 1 kg treats about 50,000 litres of water, thus offering a long life
