How does chlorine disinfect drinking water?
ChemistryPublic Health
Quick Answer
Chlorine kills or disables many harmful microbes by reacting with their cell structures and enzymes. Small controlled amounts are used so water stays safe while remaining drinkable.
The Full Story
Chlorine has been used in municipal water treatment for more than a century because it is effective against bacteria and many viruses. In water, it forms disinfecting species such as hypochlorous acid, which damage microbial cells. Cities adopted chlorination widely in the early 1900s after outbreaks of waterborne disease. Modern systems carefully monitor chlorine levels to balance safety and taste.
Key Facts
1.Chlorination became widespread in the early 1900s
2.Hypochlorous acid is the active disinfecting species
3.Dose must be carefully controlled
