Introduction: Why Iron in Borewell Water Is a Serious Problem
In many parts of India, especially rural and semi-urban areas, borewell water is a primary water source. However, it often contains high levels of iron, leading to problems like:
Reddish stains on sinks and clothes
Foul metallic taste
Clogged pipes and fixtures
Reduced efficiency of RO systems
Negative impact on health
To solve this, choosing the right iron removal media is critical.
What Causes Iron Contamination in Borewell Water?
Iron is naturally present in underground rock layers. When water passes through these layers, soluble ferrous iron (Fe²⁺) dissolves in it. Once this water comes in contact with air, the iron oxidizes to ferric iron (Fe³⁺), forming reddish-brown particles.
Common Types of Iron Found in Borewell Water
| Iron Type | Appearance | Removal Method |
|---|---|---|
| Ferrous Iron | Clear (soluble) | Oxidation + filtration |
| Ferric Iron | Reddish (insoluble) | Filtration |
| Organic Iron | Yellowish | Oxidation + adsorption |
| Bacterial Iron | Slimy reddish | Chlorination + filtration |
Each type requires specific media or treatment combinations.
What Is Iron Removal Media?
Iron removal media are specialized filter materials designed to oxidize, adsorb, or trap iron particles in borewell or groundwater. These are installed in:
Pressure sand filters
Multigrade filters
Dual media filters
Iron removal units (IRUs)
Types of Iron Removal Media for Borewell Water
1. Manganese Dioxide (MnO₂) Media
Most effective for oxidation of ferrous to ferric iron.
Works without added chemicals (if pH is right).
Ideal for high iron levels up to 10 ppm.
Starke’s StarMnox offers >85% MnO₂ content for high performance.
2. Coated Sand Media
Low-cost option.
Lower MnO₂ content (5–10%).
Suitable for iron <3 ppm.
Needs more frequent replacement.
3. Manganese Greensand
Coated sand with manganese.
Requires potassium permanganate (KMnO₄) regeneration.
Good for combined iron + manganese removal.
4. Activated Alumina (for Fluoride + Iron Combo)
Can remove fluoride along with iron.
Needs periodic regeneration.
✅ Factors to Consider While Choosing Iron Removal Media
| Factor | Importance |
|---|---|
| Iron concentration | Higher concentrations need pure MnO₂ media |
| Type of iron | Soluble vs. insoluble vs. organic |
| pH of water | MnO₂ performs best at pH 6.5–8.5 |
| Flow rate | Media selection depends on contact time |
| Backwash capability | Ensure proper setup to avoid clogging |
| Local availability & support | Choose a supplier with technical expertise |
