Using Hydrogen Peroxide to Remove Iron from Water

Using Hydrogen Peroxide to Remove Iron from Borehole Water

Hydrogen peroxide (H₂O₂) is a powerful oxidizing agent that can be used to effectively remove iron from borehole or well water. Iron is a common problem in groundwater and can cause unpleasant discoloration, staining, and a metallic taste, while also damaging pipes, fittings, and appliances. Fortunately, hydrogen peroxide offers a simple and environmentally friendly solution.

How Hydrogen Peroxide Removes Iron

When hydrogen peroxide is added to water containing dissolved iron, a chemical reaction occurs between the iron ions and the hydrogen peroxide. This process converts soluble ferrous iron (Fe²⁺) into insoluble ferric iron (Fe³⁺), forming tiny iron oxide particles. These particles can then be easily filtered out, leaving your water clear, fresh, and free of any metallic taste or odor.

Advantages of Using Hydrogen Peroxide

✅ Effective Oxidation: Hydrogen peroxide quickly reacts with iron, providing fast and efficient removal.
✅ Eco-Friendly: It breaks down into water and oxygen after the reaction, leaving no harmful chemical residues.
✅ Improved Taste & Clarity: The result is cleaner, clearer, and better-tasting water.
✅ Affordable Solution: Hydrogen peroxide systems are cost-effective and easy to maintain compared to more complex filtration setups.

Important Considerations

While hydrogen peroxide works exceptionally well for removing dissolved (ferrous) iron, it may not be as effective for ferric (oxidized) iron, which is already insoluble. For water with high ferric iron content or a mix of iron types, combining hydrogen peroxide with additional filtration methods—such as sediment or oxidation filters—may be necessary.

The correct dosage and contact time depend on the iron concentration in your water. It’s best to have your borehole water professionally tested to determine the appropriate treatment levels.

Conclusion

Hydrogen peroxide offers a reliable, natural, and cost-effective method for removing iron from borehole water. By converting iron into easily filterable particles, it helps eliminate discoloration, unpleasant tastes, and potential plumbing issues. Always test your water and consult a professional to ensure you’re using the right approach for your specific water conditions.

Clean, clear water is only a few drops away—with the power of hydrogen peroxide.
