Why chlorine is used in water treatment?
Chlorination is the process of adding chlorine to drinking water to kill parasites, bacteria, and viruses. Using or drinking water with small amounts of chlorine does not cause harmful health effects and provides protection against waterborne disease outbreaks.
Why is chlorine used in pools?
The most common chemical used in the treatment of swimming pool water is chlorine. It not only eliminates bacteria and algae by disinfecting (killing) action, it also oxidizes (chemically destroys) other materials such as dirt and chloramines.
Is chlorine used in drinking water?
Drinking water chlorination is the addition of chlorine to drinking water systems. It is the most common type of drinking water disinfection. Disinfection kills bacteria, viruses, and other microorganisms that cause disease and immediate illness.

What are some interesting facts about chlorine?
– Only fluorine is a lighter halogen than chlorine. It is the second most common halogen on Earth. Chlorine has been in use for thousands of years in other forms, but it wasn’t named until 1810 by Sir Humphry Davy.[1] – Around 1.9% of the ocean’s mass is composed of chlorine atoms. Chlorine gas was used by the Germans in WWI to poison the Allied soldiers. It has a high density for a gas of 3.21 grams per liter (air is around 1.29 grams per liter). Chlorine is used to make chlorofluorocarbons or CFCs.[2] – Chlorine is classified as an element in the ‘Halogens’ section which can be located in group 7 of the Periodic Table. The term “halogen” means “salt-former” and compounds containing halogens are called “salts”.[3]
