It can effectively kill bacteria, viruses and other microorganisms in water, thereby reducing the risk of waterborne diseases. The following is a detailed description of the application of chlorine in water treatment:
Disinfection As an effective disinfectant, chlorine is usually added to water during the water treatment process in the form of chlorine gas, chlorophyll acid or chlorine. This process is called chlorination, which ensures that pathogens in the water are effectively eliminated. Chlorine's disinfection ability comes from its strong oxidizing properties, which can destroy the cell structure of microorganisms to achieve the purpose of disinfection.
Disinfection By-products Despite the obvious benefits of chlorine in disinfection, there are also some negative effects. Chlorine disinfection may lead to the formation of disinfection by-products such as chloroform and chloroform, which may pose potential health risks in high concentrations. Therefore, when using chlorine for water treatment, the chlorine content needs to be strictly controlled to ensure the safety of the water.
Chlorine Measurement and Control Monitoring and controlling the chlorine content in the water treatment process is very critical. Total chlorine is the total amount of all forms of chlorine in water, including free residual chlorine, combined residual chlorine and other forms of chlorine such as chlorinated hydrocarbons. Available chlorine refers specifically to the part of chlorine in water that has bactericidal ability, including free residual chlorine, some combined residual chlorine (such as monochromatic and diamorphine) and chlorine dioxide. The measurement of available chlorine is crucial for evaluating the disinfection effect of water.
In summary, the application of chlorine in water treatment is mainly as a disinfectant to kill pathogens in water through its strong oxidizing properties. However, the use of chlorine also needs to be cautious to avoid the generation of harmful disinfection by-products, and other safer disinfectants such as chlorine dioxide can be selected when necessary.
