Which chemical is an effective oxidant for controlling iron and manganese, as well as addressing taste and odor issues?

• A. Chlorine
• B. Potassium permanganate
• C. Sodium hypochlorite
• D. Hydrogen peroxide

Answer: (B)

Potassium permanganate is widely recognized as an effective oxidant for controlling iron and manganese in water treatment applications. Its strong oxidizing properties allow it to effectively convert dissolved iron and manganese into their solid forms, which can then be removed through filtration. This process is crucial in ensuring water quality by reducing the potential for staining and establishing a more favorable aesthetic profile. Additionally, potassium permanganate is also utilized to address taste and odor issues commonly associated with various compounds in water. By oxidizing these compounds, it helps to improve the overall palatability and smell of the water, making it more acceptable for consumption. In contrast, while chlorine and sodium hypochlorite are effective disinfectants and can also help manage some taste and odor issues, they are not as specialized as potassium permanganate when it comes to directly targeting iron and manganese. Hydrogen peroxide acts as an oxidizing agent but is less commonly used for iron and manganese removal compared to potassium permanganate, making the latter a superior choice for these specific water treatment challenges.
