What type of disinfectant is often used for temporary water systems?

Chlorine dioxide is a commonly used disinfectant for temporary water systems due to its effectiveness in eliminating a wide range of pathogens, including bacteria, viruses, and some protozoa. It operates effectively over a broad pH range and is less affected by the presence of organic materials compared to other disinfectants. This makes it especially suitable for temporary water systems, which may experience variations in water quality and sampling conditions.

Chlorine dioxide has a rapid reaction time and provides residual disinfection, which helps in maintaining water quality during temporary use. Its ability to minimize the formation of harmful disinfection byproducts, such as trihalomethanes, also makes it an appealing choice for managing water safety.

In contrast, other disinfectants may have limitations in effectiveness, suitability, or safety profiles when applied in temporary systems, making chlorine dioxide the preferred option in such scenarios.
