Break point chlorination: It may be defined as the chlorination of water to such an extent that not only living organism but also other organic impurities in water are destroyed. When chlorine is added to water, it is used for different reactions like oxidation of oxidizable substance, chlorination of organic substance, destructive oxidation of organic substances and disinfection of pathogens. Initially all the chlorine added is consumed and there is no free chlorine. This is due to complete oxidation of oxidizable substances. As the applied chlorine increases, there is steady increase in amount of residual chlorine. This stage corresponds to formation of chloro-organic compounds and chloramines when the dose of chlorine increase, destruction of chloro organic and chloramines takes place. Addition of chlorine in such dosages is known as break point or free residual chlorination. The breakpoint chlorination ensures complete destruction of organic compounds, which give colour, unpleasant odour and bad taste. In addition to it a complete destruction of disease producing micro-organisms is also ensured.
