How often does the indoor swimming pool change water?

Almost all indoor swimming pools use 24-hour circulating filtration, disinfectant sterilization or ozone sterilization, but the cycle of completely changing water is different.

The standard swimming pool is equipped with a complete water circulation treatment system, which ensures the water quality to meet the standard through the treatment processes such as sedimentation, filtration, disinfection and heating.

According to the current regulations of the state, the swimming pool should be replenished with fresh water regularly every day, which is mainly the water lost by the swimming pool every day, generally accounting for only 5% to 65,438+00%. It is not necessary to completely change the water every day and add disinfectant (or ozone) for 24-hour circulation filtration. The state has relevant regulations on the water quality of swimming pools. As long as the pH value, free residual chlorine, combined residual chlorine, total coliform bacteria and urea are within the specified range, it will not endanger people's health. Among them, the residual chlorine content is very important. If it is low, it will affect the disinfection effect, and if it is high, it will irritate the skin and eyes.
