Swimming is a popular sport for people in summer, but bacteria and other plants grow easily in swimming pools in summer, which not only affects people's visual effects, but also poses a threat to swimmers' physical health. But in order to ensure that the pool does not affect health, it is important to pay extra attention to the safety of the pool water. Just like in the 2016 Rio Olympics, the swimming pool turned green overnight, and it was found that the reason was actually caused by moss and floating algae in the swimming pool.
To remove algae in swimming pools, copper sulfate or clear water should be added first. Generally, the amount of algae added in the algal stage is 1-2 times that of the usual time. Because algae in the non-algal stage swimming pool are few, and algae are abundant after the pool water turns green, sufficient algicides must be added to kill algae well. After adding the algicide (copper sulfate or clear water algicide), the circulation system should be opened, so that the agent in the water better mix evenly, better play its effect. About 2 hours, then add cross-linked with different cyanuric acid disinfectant (disinfection powder or sterilization), to join the standard per 1000 cubic metres of water plus 4 kg dosing, and plus 2 kg per 1000 cubic metres of water at ordinary times is different, this also is we often say to the impact of treatment or super chlorine treatment, this will make the water in the swimming pool for sterilization and disinfection.
After about 2 hours, test the PH of the pool water. Generally, the PH value of water treated with rain and trichloroisocyanuric acid disinfectant will be low, so the PH value of water can be increased by using a PH regulator, and the PH regulator is calculated by adding 10kg of water per 1000 cubic meters to increase 1 degree. It is best to adjust the PH to 7.5.
In the evening add a precipitant: polyaluminium chloride. The addition of polyaluminium chloride at a rate of 5-8kg per 1,000 cubic metres of water allows the exterminated algae and other suspended substances to settle to the bottom of the pool. The next day use a suction machine to remove sediment from the bottom of the pool. Through the above several processes can solve the problem of swimming pool moss.
