The standard and influence of PH value in swimming pool

The change of the pH value of the swimming pool will directly affect the change of the water quality. High or low will not work. The national standard for the pH value of the swimming pool is 7.0~7.8. . Next, let’s take a look at the impact of the pH value of the swimming pool.

The PH value of the swimming pool is mainly affected by the following points:

1: PH value affects the disinfection effect

If the ph value of the swimming pool is lower than 7.0, it means that the water quality is acidic. Then the Disinfectant in the swimming pool will decompose quickly and the residual chlorine will remain for a short time. In acidic medium, the reproduction speed of microorganisms will be accelerated. If the pH value of the swimming pool is too high, it will inhibit the efficacy of chlorine and reduce the disinfection and sterilization effect. Therefore, adjusting the pH value of the water to the national standard can greatly reduce the chances of bacteria and microorganisms multiplying and reduce the chance of pool water deterioration.

2: Affect swimmer comfort

When swimmers swim in water, a high or low pH value will affect human health, irritate swimmers’ skin and eyes, affect vision, and cause discomfort such as sticky hair.

3: reduce the effect of flocculation and sedimentation

If the pH value in the swimming pool is lower than the standard, which will affect the activity of the disinfectant in the water, the pH should be adjusted to 7.0-7.8 before adding the flocculation agent, so that the accelerated flocculation effect can be fully exerted and the speed of water purification can be accelerated.

4: corrosion equipment

If the pH value of swimming pool water is too low, it will affect the hardware structural equipment of the swimming pool, such as filters, heating equipment, water pipes, escalators, etc., which are highly corrosive or damaged by scaling, which will affect the appearance and service life of swimming pool equipment.

The bactericidal effect of swimming pool disinfectants depends on the pH value of the pool water. When your pH value is on the verge of testing, you need to add a pH balancer to adjust it in time. At present, there are pH regulators for swimming pools: PH plus and PH Minus. When adding, we should calculate the dosage first, and then add it several times, and detect the change of the pH value of the pool water.
