What is a common chemical oxidizer used in water treatment?

Chlorine dioxide
Potassium permanganate
Hydrogen peroxide
Sodium hypochlorite

The correct answer is: Potassium permanganate

Potassium permanganate is a common chemical oxidizer used in water treatment for several reasons. It is effective in oxidizing a range of contaminants, including iron and manganese, which are naturally occurring in water sources and can cause staining or undesirable tastes and odors. Additionally, potassium permanganate facilitates the disinfection process by breaking down organic compounds and microorganisms, improving overall water quality. This oxidizer is particularly valued for its strong oxidizing properties, allowing it to react and neutralize pollutants effectively, making it an essential component in both wastewater and drinking water treatment processes. Its ability to work at varying pH levels makes it versatile, and it can be used in both pre-treatment and post-treatment processes in water treatment facilities. While other chemicals, such as chlorine dioxide, hydrogen peroxide, and sodium hypochlorite, are also oxidizers and are commonly used in water treatment, potassium permanganate stands out due to its specific applications in degrading manganese and iron and its capability to oxidize organic materials selectively without the production of harmful by-products that are sometimes associated with other chemical treatments.
