What is chlorination and how does it work?
Chlorination destroys disease-causing bacteria, nuisance bacteria, parasites and other organisms. It also removes soluble iron, manganese and hydrogen sulfide from water. One of the main advantages to chlorination is that it is a proven technology, and chlorine provides residual protection which can protect against re contamination. Devices which continuously chlorinate a home s water supply are available, these use an injector to introduce chlorine into the system, water must be in contact with chlorine for 15 minutes to completely kill all bacteria Chlorine must be maintained at a level at which it can be tasted in water to ensure disinfection. Further treatment is often undergone in order to remove particulate matter and to de-chlorinate the water immediately before drinking using carbon filters to remove the taste and odour effects.
