Question

Quizplus · Accepted Answer

Chlorine is commonly used in both water purification and sewage treatment to provide long-term disinfection. It is a powerful disinfectant that can kill harmful bacteria, viruses, and other microorganisms. It is added to water or sewage in small amounts to ensure that it remains safe to use or dispose of. Copper sulfate is sometimes used in water treatment but not typically for disinfecting purposes, while fluorine is not commonly used for either water or sewage treatment. Activated charcoal is useful for removing certain impurities but is not a disinfectant.
