What Does Water Chlorination Mean?

Water chlorination is an important procedure to disinfect water before consumption or other purposes. Chlorination of water is a relatively simple process of adding chlorine to the water to disinfect it. This procedure helps to kill bacteria and certain microorganisms that may cause waterborne diseases.


Corrosionpedia Explains Water Chlorination

Because chlorine is a halogen, it is considered a highly effective disinfectant when added to water that is stored in water tanks, pipelines and water supply reservoirs. These containers are susceptible to the growth of bacteria and other microorganisms that, if not treated, may lead to waterborne diseases such as typhoid, dysentery and cholera.

High chlorine levels are corrosive to some of the metals used for storing chlorinated water because chlorine tends to reduce the pH level below 7. Alternatively, water with a high pH value may create flakes of calcium carbonate that can clog the pipe system and in turn reduce the water flow rate.
