Hydrogen peroxide is a strong oxidizer. In fact, it is more potent than chlorine (Cl2), chlorine dioxide (ClO2), and potassium permanganate (KMnO4). Also, through catalysis, hydrogen peroxide can be converted into hydroxyl radicals (OH). This is not to say that one technology is better than the other, but rather to make you aware of what chlorine can and cannot do and understand what role the use of hydrogen peroxide can play in water treatment.

On major advantage that H2O2 has over chlorine is that it does not form Disinfection By-Products (DBP’s) like trihalomethanes (THM) which are known carcinogens. Whenever chlorine is used, you must follow it with the correct amount of granular activated carbon (GAC) to remove the DBP’s effectively. Hydrogen Peroxide, on the other hand, does not seem to produce such DBP’s.

Water treatment professionals may have to change their thinking when comparing hydrogen peroxide to chlorine because they are two different animals. One is an excellent disinfectant (chlorine), but the other is a great oxidizer (hydrogen peroxide) and how they are utilized is dramatically different.

Chlorine requires contact time, which is typically 20 minutes for every gallon per minute of flow. Therefore, if you are flowing 10 GPM, you need 200 gallons of contact time (10 GPM x 20 minutes = 200 GPM). On the other hand, hydrogen peroxide is not a good disinfectant but rather an excellent oxidizer. It does not require contact time. Contact time only dilutes its ability to oxidize. Therefore, you do not want to use hydrogen peroxide with a retention tank.

High Iron Removal

Hydrogen peroxide excels at iron oxidation, enabling the effective removal of high iron concentrations. This makes it a superior choice for treating water in areas with significant iron contamination.

No Disinfection By-Prod

Unlike chlorine-based treatments, hydrogen peroxide doesn’t create harmful disinfection by-products (DBPs) such as trihalomethanes (THMs), which are known carcinogens.

Strong Oxidizer

As a potent oxidizer — stronger than chlorine, chlorine dioxide, and potassium permanganate — hydrogen peroxide can effectively break down many organic contaminants in water.

No Residual Chemicals

Hydrogen peroxide decomposes into water and oxygen, ensuring that no residual chemicals affect the taste or safety of your treated water.

Versatile Application

From mitigating microbial contaminants to treating sulfur and manganese, the versatile application of hydrogen peroxide provides an encompassing solution for diverse water treatment needs.
