In the process of treating sewage, disinfectants are indispensable. Of course, there are various disinfectants, but the most commonly used one is chlorine disinfectant. Then why is it necessary to monitor the total residual chlorine when using a large amount of disinfectants? The reason is very simple. Please read on!

The amount of chlorine disinfectant added to water is directly proportional to the amount consumed in the water and the content of pollutants. That is to say, the amount of disinfectant consumed corresponds to the amount of pollution in the water. After the disinfection treatment is completed, the disinfectant will no longer be consumed, and what remains is the total residual chlorine. If this residual chlorine exceeds the standard, it will also be harmful to the human body. It has toxic and carcinogenic effects. Therefore, while using a large amount of disinfectants, it is also essential to monitor the total residual chlorine properly. Do not cause unnecessary consequences due to excessive total residual chlorine in water that has been disinfected and treated!

What Instrument is Used to Monitor the Total Residual Chlorine in Water?

An instrument called “Total Residual Chlorine Online Analyzer” produced by Hangzhou Modi is used to monitor the content of total residual chlorine in water in real time. The working principle is that water samples and anti-interference agents are automatically injected into the reactor. It will automatically add characteristic chromogenic agents to carry out the chromogenic reaction and measure the absorbance of the reactants. The instrument then detects the total residual chlorine content in the water through the habituation value.
