At Robert Dennis Well Drilling, we use a custom hydrogen peroxide injection system for sulphur and iron removal. All hydrogen peroxide injected in this system is 100% food grade and will be safely removed from the water once it is filtered out leaving you with no smell, no odour, no foul taste and no iron in your water under proper installation.

Hydrogen peroxide (H202) is a powerful oxidizing agent, much more powerful than aeration, chlorine or potassium permanganate. Hydrogen peroxide decomposes into oxygen and water leaving no trace of chemical residues. For problem well water containing iron, iron bacteria, manganese and/or “rotten egg” sulfur odour “H2S” (hydrogen sulfide gas) hydrogen peroxide systems are an excellent choice.

When peroxide is added to water, a large amount of dissolved oxygen is released and a powerful oxidizing effect occurs. Coliform and iron bacteria are killed, and tannins are oxidized. This type of iron filter system handles the absolute worst type of water reliably and effectively. Peroxide oxidizes the iron, manganese and sulfur odours to a solid form that the catalytic carbon can remove.

Benefits of a Hydrogen Peroxide Water Treatment System:

  • Eliminate sulfur odors
  • Remove hydrogen sulfide gas
  • Kill iron and sulfur bacteria
  • No chemical residuals
  • Great tasting water
  • Low maintenance

FAQs About Using Hydrogen Peroxide to Treat Iron:

Q. How does hydrogen peroxide treat very bad water with iron and sulfur odours?

A. When water is underground in most wells, iron is in a clear, also known as ‘ferrous’ or clear water iron. Iron filters must take this clear iron and transform it to rust or ferric iron in the process known as oxidation. Peroxide is a powerful oxidizer, and by adding very small amounts to water before the automatic carbon backwash filter, iron is transformed into a form that the carbon filter can remove.

Q. What is the advantage of hydrogen peroxide as opposed to chlorination?

A. Hydrogen peroxide is made from hydrogen and oxygen and when it’s added to water it rapidly breaks down into hydrogen and water. After the peroxide thoroughly treats the iron, odour and kills iron bacteria, there is no chemical residual left. Chlorine bleach is sodium hypochlorite so there is a small sodium residual added to the water after chlorine interacts with iron and odours.

Q. Won’t I smell and taste the peroxide?

A. No. The carbon backwash filter removes all trace. The metering pump that injects the peroxide is adjustable so very low levels are injected, just enough to treat the water properly.

Hydrogen Peroxide & The Environment

  • Hydrogen peroxide also has a wonderful quality of being good for the environment!
  • This benefit goes deep and wide. It is good for rivers, it is good for plants, and it can be used to replace chlorine bleach, ammonia, and other chemicals which are harmful to rivers and plants.
  • H2O2 is good for people, animals, plants, rivers……and it breaks down into water and oxygen – what could be more nontoxic?
  • H2O2 is part of the earth’s cleaning cycle. It is formed as water (H2O) passes through the ozone layer (O3) where it picks up another oxygen atom (O) becoming H2O2 (hydrogen peroxide). So, a bit of it comes down to us in rain.
  • When you water your plants with the garden hose, there’s no hydrogen peroxide in that water. Adding a little hydrogen peroxide to plant water is great for the garden (indoor plants too).
  • H2O2 is also produced by the human immune system to help fight off infections. White blood cells make it.
