Chlorine dioxide water treatment has advantages over chlorine, ozone, UV and other methods. Learn about pros, cons, dosing, and compliance.
Chlorine dioxide is an effective and popular water treatment solution. Dissolved into water, it creates a powerful, yet selective oxidant, biocide, and disinfectant used for both treating drinking water and commercial treatment applications.
Powerful Disinfection in Water Treatment. Chlorine dioxide is a disinfectant. When added to drinking water, it helps destroy bacteria, viruses and some types of parasites that can make people sick, such as Cryptosporidium parvum and Giardia lamblia.
Granstrom and Lee (1958) surveyed water treatment plants believed to be using chlorine dioxide. The majority of respondents (956 plants) were using it for taste and odor control. Other uses reported were algal control (7 plants), iron and manganese removal (3 plants), and disinfection (15 plants).
We most commonly see utilities with high TOC source water adding or switching to chlorine dioxide in their treatment programs to reduce chlorine-derived disinfection byproducts (DBPs) such as Trihalomethanes (THM) and Haloacetic acids (HAA5).
Produced a handbook on the state of the science and best practices for chlorine dioxide in drinking water treatment, including U.S. and European experience. Includes information on current regulations, production (generation) technology, and various uses of chlorine dioxide as a disinfectant and oxidant.
Regardless of the generation method chosen, chlorine dioxide offers several key benefits for water treatment: High Disinfection Efficacy : Chlorine dioxide is effective at low concentrations, meaning less chemical is required to achieve the desired level of disinfection.
This chapter contains sections titled: Introduction. Chemical and Biologic Properties. Equipment and Generation. Use in Drinking Water and Wastewater Disinfection. Other Disinfection Applications. Other Uses for Chlorine Dioxide in Water Treatment. Analytic Methods for Chlorine Dioxide and its Oxychlorine.
Chlorine dioxide stands out as a sustainable solution for water treatment, offering effective disinfection, minimal environmental impact, and cost-efficiency. Its ability to control odors, remove biofilms, and enhance water quality makes it a valuable tool in the quest for clean and safe water.
Chlorine dioxide (ClO₂) emerges as a disinfectant that not only provides effective microbial control but also offers significant environmental advantages compared to traditional treatment methods, in line with Environmental Protection Agency (EPA) guidelines for water quality and safety.
