Iron Removal Plant

An Iron Removal Plant is designed to remove excess iron and impurities from groundwater or raw water sources to make the water clean, safe, and suitable for domestic, commercial, and industrial use. By removing iron, the system improves water taste, odor, and clarity while protecting pipelines, RO systems, and household equipment from rust and clogging.

🌊 Why Iron Removal is Needed

• High iron in water (greater than 0.3 mg/L) causes:
  • Reddish-brown stains on clothes, utensils, and plumbing
  • Metallic taste and unpleasant odor
  • Clogging of pipes and RO membranes
  • Promotes iron bacteria growth and slimy deposits
  • Not suitable for drinking or industrial applications

🏭 Iron Removal Plant – Basic Process

An Iron Removal Plant removes dissolved and precipitated iron from water. The treatment technology depends on the form of iron (ferrous or ferric) and the concentration present in the water.

1. Aeration and Filtration (Most Common)

• Water is exposed to air using aerators or cascade systems
• Ferrous iron converts into ferric iron and forms particles
• Particles are removed through sand or dual media filters
• Best for iron levels below 10 ppm

2. Manganese Dioxide Media

• Greensand, Birm, or Pyrolox media oxidize iron on contact
• Regeneration using potassium permanganate or chlorine
• Effective for iron and manganese removal
• Suitable for higher iron concentration

3. Chemical Dosing and Filtration

• Chlorine, ozone, or sodium hypochlorite added to oxidize iron
• Iron precipitates and removed through filtration
• Suitable for industrial and high iron water treatment

4. Pressure Filter System

• Water passes through sand, anthracite, and media layers
• Removes oxidized iron and turbidity
• Compact and efficient system

5. Biological Iron Removal

• Uses natural bacteria to oxidize iron
• Eco-friendly and low chemical usage
• Suitable for municipal and rural systems
