Residual chlorine and total residual chlorine are two concepts often mentioned in water treatment processes, both of which are related to water quality and disinfection by-products. Residual chlorine refers to chlorine that has not fully reacted during the disinfection process of water treatment, while total residual chlorine refers to the sum of free chlorine and chloramine disinfection by-products in water. Although both are related to chlorine, their meanings and effects are different

The meaning of residual chlorine is different from that of total residual chlorine. Residual chlorine refers to the chlorine added during the disinfection process of water treatment, which is used to eliminate bacteria and viruses in water and ensure water quality safety. And total residual chlorine includes free residual chlorine and chloramine disinfection by-products, which is a comprehensive indicator that reflects the action of chlorine and the generation of by-products in the water treatment process

The impact of residual chlorine and total residual chlorine on water quality is also different. Residual chlorine within a certain range can ensure the safety of water quality, but excessive or insufficient residual chlorine content can have a negative impact on water quality. Excessive residual chlorine content can produce irritating odors and odors, affecting human health, while low residual chlorine content cannot effectively disinfect, increasing the risk of bacteria and viruses in water. However, total residual chlorine more reflects the disinfection by-products that may be generated during the water treatment process, such as chloroform, dichloromethane, etc., which can have a certain impact on human health

For household drinking water, understanding the meaning and impact of residual chlorine and total residual chlorine is crucial. When choosing household water purification equipment, it is not only necessary to consider its removal effect on residual chlorine, but also the removal effect on total residual chlorine. Because the impact of disinfection by-products in total residual chlorine on health is equally important and cannot be ignored

In summary, residual chlorine and total residual chlorine are two important water quality indicators, both of which play important roles in water treatment processes. Understanding their differences and their impact on water quality can help us better ensure the safety of household drinking water. I hope everyone can pay attention to water quality issues in their daily lives, choose safe and reliable drinking water, and ensure the health of themselves and their families.
