2. Add TCCA (sodium trichloroisocyanurate), and add disinfectant at the ratio of 3-5Kg per thousand tons of water (twice the amount of fresh water). Sprinkle evenly and start the circulating pump. After two hours, the residual chlorine was detected. If the residual chlorine is less than 0.5ppm, add disinfectant. Add and test disinfectants every day. When the residual chlorine in the pool water is not up to standard, disinfectant should be added in time. The new national standard is (0.2- 1.0ppm)(CJ244-2007).
3. Adjust the PH value of water (it is best to control the PH value between 7.4 and 7.6), and the dosage should be measured to PH7.8-8.5 through hydration test (because the result measured by hydration test is higher than the actual value). When the PH value is low, simply dissolving ozone powder can improve the pH value.
4. If the water quality is turbid or colored, and the turbidity of the water can't reach the standard, it is necessary to add an enzyme clarifier for absorption, which can be added through dosing pump (the effect is not fast). If the problem needs to be solved quickly, it can be directly added to the pool water at the ratio of 200g per100t of water. When enzyme clarifier is added, dilute it with 50- 100 times of water, directly sprinkle it into the pool, start the circulating pump 1-2 hours and let it stand for 8 hours. If long-term preservation is needed, it can be added daily at the rate of 50g per 100t of water. Enzyme clarifier is a biological extractant, which is non-toxic and free from secondary pollution, and can be added at any time, thus solving the problem that A and B solutions are not completely flocculated and need to be absorbed manually. (The turbidity NTU of the new national standard is less than 1)
5. Adding ozone powder can quickly kill bacteria, spores and viruses in water. It can also degrade various organic substances, deodorize, decolorize, remove chlorine odor and decompose chloramine, and at the same time, it can also decompose oil stains in water and solve the problems of pool wall sticking and slipping. The dosage is 50g per100t of water. (The half-life of ozone powder in water is 20 minutes, so it is recommended to add it 1 hour before opening. )
Note: A: Angel Blue and disinfectant cannot be added at the same time, otherwise copper precipitation will occur.
B: Disinfectant and alkali can't be put in at the same time, otherwise the disinfection effect will be reduced.
C: High concentration of ozone is harmful to human body. It is recommended that the dosage should be small, and it is best to add it 1 hour before opening the bottle.
First aid method when swimming pool water becomes turbid: add 500g of enzyme clarifier and 500g of disinfectant to every 100t of water, and circulate for 2 hours to stand.
