What is the reasonable content of total residual chlorine?

When it comes to total residual chlorine, it refers to the content of total residual chlorine, which includes free ion residual chlorine and combined Sexual residual chlorine. So how much total residual chlorine content in water is reasonable? How do we know it's reasonable? In this chapter, the manufacturers of water quality online monitors come to understand this problem with you! What is the reasonable content of total residual chlorine? my country's standard for residual chlorine content is: free residual chlorine in factory water should not be lower than 0.3mg/L after 30 minutes of contact, and should not be lower than 0.05mg/L at the end of the pipe network. That is to say, if we do not purify tap water, then the drinking water we drink every day will contain at most 0.05MG/L residual chlorine. Once the total residual chlorine in water exceeds the standard, it will have an impact on human health. Drinking tap water with high residual chlorine content for a long time may cause cancer risk. Taking a bath can also increase symptoms such as skin itching. So how do we know that the total residual chlorine in the water exceeds the standard? The total residual chlorine in water can be monitored in real time by the total residual chlorine online analyzer. The monitoring process is: after the water sample and anti-interference agent are automatically injected into the reactor, then the characteristic chromogenic agent is automatically added for color reaction, and the reaction is measured. The absorbance of the substance; the online analyzer can directly measure the content of total residual chlorine in the effluent through the absorbance value. Therefore, don't think that drinking water will be safe after being disinfected with a disinfectant. You should also consider whether the residual chlorine in the water after using the disinfectant exceeds the standard, so as to avoid unnecessary harm!
