Chlorination is a water treatment process that involves the addition of chlorine or chlorine compounds to water in order to disinfect it and make it safe for drinking. Chlorine is a highly effective disinfectant that can kill a wide range of pathogens, including bacteria, viruses, and protozoa. It is commonly used in municipal water treatment systems around the world to ensure the safety of drinking water. The process of chlorination can also help to control the growth of algae and other microorganisms in water storage and distribution systems. However, there are some concerns about the potential health risks associated with the byproducts of chlorination, such as trihalomethanes, which have been linked to certain health issues. Researchers continue to study the effects of chlorination on drinking water quality and explore alternative disinfection methods to address these concerns.
