The main purpose:

As the most commonly used swimming pool disinfection desk at home and abroad, it is effective against intestinal pathogenic bacteria, densococcus and A, B

Hepatitis B virus has a strong inactivation effect, which can prevent bacteria from exceeding the standard in the water and the water body from turning green.


To use this product as a swimming pool disinfectant, it is best to divide it into two doses, one after the end of the day and the other one or two hours before the opening. This product is a chlorine-containing disinfectant and is volatile. The speed of volatilization is directly related to sunlight and temperature. In summer, the sun is violent and the disinfectant is easy to volatilize in hot weather. If the disinfectant is added after the end of the day, the temperature at night is relatively low and there is no sunlight, which can keep the disinfectant longer effective, which can more thoroughly and effectively disinfect the water of the swimming pool; the next day Depending on the opening time of each swimming pool, the residual chlorine can be detected 1-2 hours before the opening. If the residual chlorine is low, an appropriate amount of disinfectant can be added to make the residual chlorine meet the sanitary requirements. If the disinfectant is added prematurely, the volatilization will be finished soon, and the residual chlorine will not reach the standard by the opening time.

How to use swimming pool disinfection tablets:

The chlorine content of the disinfection tablets is ≥50%, which is a fast-dissolving tablet, which means that it can be dissolved in about 10 minutes after being spilled into the swimming pool. In order to make the residual chlorine in the swimming pool reach the standard and maintain good water quality more effectively, 2 to 4 grams of disinfectant tablets should be added to each cubic meter of water. (2-4kg/1000 cubic meters). After the disinfection tablets are added to the swimming pool, the calculation formula for residual chlorine: (take 1 cubic meter to cast 2 grams--1 disinfection tablets as an example) 2gX 50%X 1000=1000mg (available chlorine contained in 2 grams of disinfection tablets, Unit: milligrams); 1000mg 6 1000L (1 cubic) = 1mg/L (also known as 1ppm).That is to say, if 1 cubic water is added to a disinfectant tablet, if it is not consumed, its theoretical concentration is: 1mg/L. Generally speaking, after adding a disinfectant, the disinfectant will definitely interact with bacteria and algae in the water ( It will also be partly consumed by organics in the water). Because the water quality of each swimming pool is different, the measurable residual chlorine concentration of different swimming pools after adding the same number of disinfection tablets is also different. The water quality is good, and the remaining chlorine If the water quality is high, the remaining chlorine should be low.Therefore, we recommend that at least 2 kg/1000 cubic meters should be added at night:If the water quality has turned green or white, it is best to add more.When adding disinfectant tablets 1-2 hours before the swimming pool opens, it’s best to detect residual chlorine first, and thenAdding 2 kg of disinfectant tablets to 1000 cubic meters can increase the ratio of 1 mg/L to calculate the dosage. For example, if a 500 cubic swimming pool needs to increase by 0.5 mg/L, then 0.5 kg of disinfectant tablets should be added.
