The primary goal of chlorination in water treatment is to disinfect and kill pathogens in the water. Chlorination is a critical process used to maintain the safety and quality of drinking water by effectively targeting harmful microorganisms such as bacteria, viruses, and protozoa. When chlorine is added to water, it reacts with these pathogens, effectively neutralizing them and making the water safe for human consumption. This disinfection process helps to prevent waterborne diseases and is an essential step in ensuring that water meets public health standards.

While some may think of chlorination in terms of taste or other water characteristics, its fundamental purpose remains focused on safeguarding public health through effective disinfection. Enhancing flavor, improving color, or increasing temperature are not the primary functions of chlorination, as these aspects can be addressed by other treatment processes or measures. Thus, the focus remains squarely on using chlorine as a powerful tool for maintaining water safety through disinfection.
