Swimming pool management in order to meet national pool water quality standards, commonly used chemicals are: chlorine tablets, chlorine powder, algaecide, pH+, precipitating agent. A separate chlorine test box is available to test pH and chlorine content. According to the flow of people in the pool, this article will give suggestions on the amount of chlorine in different places, and the use of other pool cleaning agents and the amount of use in accordance with the principle of saving the cost of chlorine tablets.
The amount of chlorine in different places
Foot soaking basin
The residual chlorine of the foot dip tank should reach 5-10ppm, and add 2 grams of chlorine tablets to the pool chlorine floater each time, 5-10 tablets/ton of water (generally change the water every four hours before re-dosing).
Wash room floor disinfection.
The residual chlorine should reach 250-500ppm. Add 2 grams of chlorine tablets, 1-2 tablets, into 4 liters of water every night to prepare a disinfectant, and then use a mop to remove the venom and wipe the surface to be sterilized.
Public swimming pool water disinfection
For 2091 tons per day, 4-8 kg of chlorine tablets are needed. Generally choose to be put at night, can be evenly put into the pool water or through the pool chlorine floater into the pool water. The chlorine content and pH value should be monitored half an hour before the opening of the park on the next working day. If the residual chlorine is less than 0.3mg/ L, 2 kg of chlorine tablets should be added. In the afternoon, half an hour before the opening of the museum and then monitor the residual chlorine and pH value, if the residual chlorine is less than 0.3mg/ liter, it is appropriate to add 2 kilograms of chlorine tablets (the specific dosage can refer to the usual number of swimmers, the more people, the more easy to lose chlorine, generally 1000 people, 1 hour will lose 0.1ppm chlorine), and then continue to add 4-8kg chlorine tablets to the pool chlorine floater before closing the park.
Clarification treatment
The water needs to be clarified with an enzyme clarifier every 3-5 days. Every 3-5 days, 3 bottles of enzyme clarifying agent need to be added, and after backwashing the filter, the circulating filtration system is started, and the water quality begins to be clarified. When the pool water appears serious turbidity treatment, the dosage is doubled; When there is discoloration such as algae, the rule should be doubled. It is recommended that every half month to a month, the precipitation agent is added to the water for precipitation suction treatment.
The use of algaecides.
Under normal circumstances, if the chlorine content is always maintained at 0.3-1.0ppm, or if the chlorine tablets and enzyme clarifying agents are doubled in time after rain, algae problems will not occur. There are two kinds of algaecide, traditional copper sulfate algaecide and non-bubble algaecide, which can be selected. What if the water turns green after the rain? It turns green because the swimming pool grows all kinds of very tiny plants, algae. There are hundreds of different types of algae. Algae can multiply rapidly in the water and turn the clear water into a stagnant pool in a day. Generally, the algae problem is solved by the four-step method of eliminating algae.
- Step 1: No bubble algae removal agent for algae, when the situation is serious, the dosage can be twice the usual.
- Step 2: Apply disinfectant, twice as much as usual.
- Step 3: Inject pH regulator to adjust the pH between 7.0 and 7.8, you can use the pH test box to detect the pH of water, if the pH is greater than 7.8, you can use pH-; If pH is less than 7.0, you can use pH+.
- Step 4: If there is a slight algae problem, add enzyme clarifying agent, and finally filter and clarify.
In the case of serious algae growth, it is best to use precipitant suction treatment. Pay attention to the order of administration, otherwise precipitation will occur, or the effect of algae eradication will be affected. Generally, the amount of precipitator is 5Kg-10Kg per 1000 tons of water, which is used once every 1-2 months, and it is doubled on rainy days or when the water quality is seriously polluted, if the treatment is new water, it is also doubled. The dosage of bubble-free algaecide is weekly, diluted and evenly sprinkled, which does not affect the disinfectant delivery, and can kill algae in 8 hours without metal ion chemical residue. Non-foaming algaecide is recommended.
The use of pH elevators
Now the acid rain range is relatively large, the acidity is relatively low, and sometimes the pH value of the rain is as low as about 4. The pH value of our swimming pool water should be kept at 7.0-7.8 as far as possible, so as to ensure the disinfection effect and maximize the cost savings. At this point you can use pH+. Add 8 grams of pH+ per ton of water per 1 degree pH increase to solve the problem of low pH. Use when detecting pH deviation from pH 7.0-7.8.
