The principle of dechlorination boiler is to boil water and then boil it for a few minutes, so that the residual chlorine in the water becomes gas to reduce the residual chlorine content in the water.
As an effective sterilization method, residual chlorine is still adopted by more than 80% water plants in the world. Therefore, a certain amount of residual chlorine must be kept in municipal tap water to ensure the safety of microbial indicators of drinking water.
However, water pollution has become more and more serious in recent years, which directly leads to the increase of residual chlorine content in tap water. Therefore, drinking boiled water directly from tap water is not a healthy choice, and re-purification of tap water is the key.

Harm of problem tap water
Many halogenated compounds produced by the combination of organic substances in water and chlorine-containing disinfectants have been proved to be carcinogens, among which volatile trihalomethane and non-volatile haloacetic acid are the main ones, and the latter is 50- 100 times more dangerous than the former.
The waterworks should be disinfected with chlorine and supplied to every household, in order to ensure hygiene and safety. But once chlorine is added, if there is more organic matter in the water of the water source, it will combine with chlorine to form nitrate. Nitrate can also be reduced to nitrite in human body. Nitrite reacts with secondary amines inside and outside the human body to produce nitrosamines, which have carcinogenic, teratogenic and mutagenic effects when reaching a certain dose in the human body.
