Daily management and maintenance of swimming pool water
Routine management and maintenance are equally crucial and key to ensuring pool water quality. Therefore, pool managers need to test and record key indicators multiple times daily.
(1) Free Residual Chlorine: This is an immediate indicator of disinfection effectiveness. National standards stipulate that the residual chlorine content in pool water should be maintained between 0.3 and 1.0 mg/L. Below the lower limit, disinfection is incomplete; above the upper limit, it can irritate the skin and eyes.
(2) Foot Bath Residual Chlorine: The foot bath, which must be passed through before entering the pool, has a much higher concentration of disinfectant. National standards require it to be maintained between 5 and 10 mg/L to achieve instant sterilization.
(3) Urea Content: This reflects the degree of pool water renewal and the flow of people. The standard is ≤3.5 mg/L; exceeding this indicates the need to add more fresh water.
(4) Insufficient Fresh Water Replenishment: Even with the best circulation system, fresh tap water must be added daily to dilute contaminants and refresh the water quality. The daily replenishment volume of indoor public swimming pools should generally be no less than 5% to 10% of the total pool water.
Online monitoring provides greater peace of mind: Nowadays, many reputable swimming pools are equipped with online water quality monitoring systems that can monitor data such as residual chlorine, pH value, and turbidity in real time. If any abnormalities are detected, an alarm will be automatically triggered or the dosage of chemicals will be adjusted, making water quality management more precise and timely.
