Quenching Chlorination D.B.P.’s With Hydrogen Peroxide

Hydrogen Peroxide Reduces Chlorine Disinfection By-Product Formation In Drinking Water.

Most public water is treated with chlorine. The number one reason we want you to know about our company is to ensure you and your family have access to safe clean water. We need plenty of water to drink, shower and bathe.

During showering our bodies can absorb up to sixty percent of the liquid that comes in contact with our skin. The following article outlines research performed demonstrating the ability of Hydrogen Peroxide to reduce disinfection by products created by chlorine.

Hydrogen Peroxide Combating DBP’s.

Reactions between chlorine disinfectants, dissolved organic matter and other chemicals in water form a series of disinfection by-products (DBPs). These toxic DBP’s include trihalomethanes (THMs) and haloacetic acids (HAAs), and are being increasingly regulated.

….Thus, H2O2 acts as a quenching agent

Recent research experiments explored the effects Hydrogen Peroxide and silver has on D.B.P. formation.  During the experiment chlorine was used as a primary disinfectant and a secondary disinfectant solution comprised of Silver and Hydrogen Peroxide (Ag+/H2O2) was also administered.

The Hydrogen Peroxide/Silver solution was designed to provide long-lasting residual disinfection. Based on a series of laboratory experiments using simulated treatment and distribution systems, post-chlorination additions of the Hydrogen Peroxide/Silver disinfectant dramatically reduced the formation of halogenated DBP’s.

Testing The Source Water.

Five source waters were tested over a range of conditions, including various levels of chlorine, bromine, organic carbon, pH and temperature. For surface and ground waters, DBP reductions at 24 hours with the secondary disinfectant averaged 7229% for THMs and 67211% for HAA’s.

The dramatic reduction in halogenated DBPs occurred for all tested source waters and all disinfection conditions.

The likely mechanism is the reduction of chlorine to chloride by H2O2, which halts further reaction of chlorine with dissolved organic matter and other DBP precursors. Thus, H2O2 acts as a quenching agent, in addition to its residual disinfectant properties in combination with Ag+.

The research shows a benefit of mixed disinfectants that provide a potentially viable option for controlling the formation of DBPs while maintaining effective disinfection.
