Here are some key points about residual chlorine control in swimming pools:
Standards for residual chlorine According to the regulations of the national health supervision department, the residual chlorine in swimming pool water should be kept between 0.3mg/L-1.5mg/L. This range can not only ensure effective disinfection, but also avoid irritation to swimmers' skin and eyes caused by excessive residual chlorine. Too low residual chlorine will lead to incomplete disinfection and increase the risk of bacterial growth; while too high residual chlorine may cause human discomfort and even poisoning.
The role of residual chlorine
Residual chlorine is a residual disinfectant in swimming pool water, usually in the form of sodium hypocrite (NaClO). It has strong oxidizing properties and can effectively kill bacteria, viruses and other microorganisms in water, thereby ensuring the health of swimmers. In addition, residual chlorine can eliminate harmful substances such as organic matter and ammonia in water to keep the water clean.Residual chlorine detection method The method of detecting residual chlorine in swimming pools usually uses test strips or test kits for qualitative or quantitative detection. In addition, online monitoring instruments can be used to monitor the residual chlorine in the swimming pool in real time. These methods can help managers promptly detect and deal with situations where the residual chlorine content is too high or too low, ensuring that the water quality of the swimming pool meets the standards.
Methods for controlling residual chlorine Reasonable addition of disinfectants: According to the water quality of the swimming pool and the number of swimmers, reasonable addition of disinfectants to control the residual chlorine content within the specified range.
Regular testing: Regularly test the residual chlorine in the swimming pool to promptly detect and deal with situations where the residual chlorine content is too high or too low.
Maintain swimming pool equipment: Regularly check and maintain swimming pool equipment to ensure the water treatment effect and circulation filtration are normal, and reduce residual disinfectants and other harmful substances in the water.
Do a good job in swimmer hygiene management: Strengthen swimmer hygiene management, require swimmers to shower and rinse their feet before entering the pool, and reduce pollution sources entering the swimming pool.
Solution for excessive residual chlorine If the residual chlorine content in the swimming pool exceeds the standard range, the following measures can be taken:
Use decorating agent: Use decorating agent to quickly restore the excessive residual chlorine in the swimming pool to the normal range (0.3~0.5mg/L). This method is applicable to excessive residual chlorine caused by excessive addition of chlorine disinfectant.
Adjust the water treatment process: According to the water quality, adjust the water treatment process appropriately, such as selecting the appropriate type and dosage of disinfectant, and adjusting operating parameters such as flow rate, pH value, etc., to reduce the generation of residual chlorine.
Strengthen equipment maintenance: Regularly maintain and maintain the water treatment equipment of the swimming pool to ensure its normal operation and disinfection effect.
Through the above methods, the residual chlorine content in the swimming pool can be effectively controlled to ensure water quality safety and protect the health of swimmers.
