[Chemical Knowledge]:Residual chlorine and total residual chlorine, do you understand?

In daily life, we often hear discussions about water quality, and residual chlorine and total residual chlorine are one of the important indicators. So, what is the difference between them?
What is residual chlorine and total residual chlorine. Residual chlorine refers to the amount of residual chlorine or hypochlorous acid in the water, which is the unused part of the water after the water treatment plant adds disinfectants (such as chlorine or sodium hypochlorite) to the water. The total residual chlorine refers to the total chloride content in water, including residual chlorine, free chlorine and chloramines. Simply put, residual chlorine is the residual amount of disinfectant, while total residual chlorine is the total chloride content of the water. The effects of
residual chlorine and total residual chlorine on water quality are different. Residual chlorine is an index to measure the disinfection effect. When the content of residual chlorine is within the appropriate range, it can effectively kill bacteria and viruses in the water and ensure the health and safety of the water. However, too high or too low residual chlorine content will affect human health. Too high residual chlorine content may produce carcinogens, and too low residual chlorine content cannot be effectively disinfected. The total residual chlorine more reflects the pollution in the water, in which chloramines are harmful to the human body, so the high content of total residual chlorine will also affect health. In
daily life, the tap water we drink will contain residual chlorine and total residual chlorine, which is to ensure the health and safety of water. However, long-term drinking of water containing too high total residual chlorine may have adverse effects on health, so we should choose water sources treated by professional water purification equipment to reduce the content of total residual chlorine. In addition, it is also very important to monitor the water quality of public places such as swimming pools to ensure that the water quality meets the standards and protects public health. At the same time, government departments should also strengthen the supervision of water quality to ensure the safety of public water.
In short, understanding the difference between residual chlorine and total residual chlorine and its importance in daily life can help us better protect the health of ourselves and our families. We should not only pay attention to the quality of drinking water in our own homes, but also pay attention to the safety of water quality in public places. Actively support and participate in water quality supervision, and jointly create a healthy and safe living environment.
