What is the primary purpose of sodium hypochlorite in water treatment?

Sodium hypochlorite is primarily used in water treatment for disinfection purposes. It serves as an effective chlorine-based disinfectant that helps eliminate harmful bacteria, viruses, and other pathogens present in the water. The disinfection process is crucial because it ensures that drinking water is safe for consumption, reducing the risk of waterborne diseases.

In addition to its disinfection properties, sodium hypochlorite can also aid in oxidizing certain organic and inorganic substances, but its primary role remains focused on ensuring microbiological safety in water supplies. By providing a reliable method of disinfection, sodium hypochlorite helps maintain public health standards and protect water quality.
