Talking about why the residual chlorine in municipal water should be removed, and why should chlorine be added to the water?

First of all, let's understand, what is chlorine? Chlorine is the most effective and cost-effective bactericide and is widely used in the domestic water treatment industry. After chlorine is put into water, it can be consumed by bacteria, microorganisms, organic matter and inorganic matter in the water. That is to say, if the water in the water plant is not chlorinated, the water quality will not reach the safety level of our drinking water.

Chlorine is added to the water, after a certain period of contact, there will be residual effective chlorine in the water, because a certain amount of residual chlorine must be maintained in municipal tap water to ensure the safety of the microbial indicators of drinking water. But when chlorine reacts with organic acids, many carcinogenic by-products, such as chloroform, are produced. Exceeding a certain amount of chlorine itself will also cause many harm to the human body, and it has an unpleasant odor, that is, the smell of bleaching powder.

Excessive residual chlorine will bring harmful substances such as chloroform, but the residual chlorine dose of municipal tap water is extremely small, and it is more common to harm the skin, such as itching or inflammation.so many showerheads on the market are installed replaceable remove chlorine product filters.
