What is chlorination primarily used for in water treatment processes?

Chlorination in water treatment processes is primarily used to eliminate pathogens. The addition of chlorine to drinking water is a critical step in ensuring the water is safe for consumption. Chlorine is a powerful disinfectant that effectively kills or inactivates bacteria, viruses, and other microorganisms that may be present in the water supply. This process significantly reduces the risk of waterborne diseases, making chlorination an essential component of public health measures related to drinking water.

While there are other water treatment processes designed to adjust pH levels, enhance mineral content, or reduce odor, these functions are not the primary purpose of chlorination. The main goal is to provide a safe, pathogen-free water supply, ensuring that it meets health and safety standards for public consumption.
