Water chlorination is the process of adding chlorine (Cl 2) or hypochlorite to water. This method is used to kill certain bacteria and other microbes in tap water as chlorine is highly toxic. In particular, chlorination is used to prevent the spread of waterborne diseases such as cholera, dysentery, and typhoid.
Chlorine chemistry helps keep drinking water and swimming pools safe. Before cities began routinely treating drinking water with chlorine-based disinfectants, thousands died every year from waterborne diseases such as cholera, typhoid fever, dysentery and hepatitis A. Chlorine-based pool and spa disinfectants help keep recreational waters safe by destroying waterborne pathogens that can result in illnesses, such as diarrhea, swimmerÃ¢â‚¬â„¢s ear or skin rashes, including athleteÃ¢â‚¬â„¢s foot.
Chlorine chemistry is used to manufacture bullet-resistant vests worn by soldiers and police officers. Chlorine chemistry is also used to produce parachutes and night vision goggles as well as cockpit canopies and missile guidance technologies.
