For routine maintenance of swimming pools, ensuring the cleanliness and safety of the water is essential. Therefore, chlorinated disinfectant tablets have become the first choice for many swimming pool operators. But why are chlorine-based bactericidal tablets so popular? Starting from the advantages of pool disinfection, this article analyzes their impact on the swimming pool water environment and highlights their protective role.
Basic Introduction to Chlorinated Disinfectant Tablets
The main ingredients of chlorinated disinfectant tablets are usually trichloroisocyanuric acid (TCCA) or dichloroisocyanuric acid (DCCA). This product has a high active chlorine content, which rapidly decomposes upon contact with water, releasing chlorine that can sterilize and purify the water quality. Chlorine disinfectant tablets are divided into fast-dissolving and slow-dissolving types. The fast-dissolving type is used for rapid adjustment of water quality, such as in cases of sudden water pollution. The slow-dissolving type is suitable for long-term stable maintenance of water quality and is applicable for routine swimming pool water quality management.
Advantages of Using Chlorinated Disinfectant Tablets
1.As the preferred swimming pool disinfectant, chlorinated tablets have unique chemical properties and bactericidal action. Firstly, they are highly stable organic chlorine disinfectants that do not easily degrade in the environment. After dry storage, their active chlorine content decreases only slightly, ensuring the product’s long-term disinfecting and storage stability.
Hydrolysis in Water:
2.In the hydrolysis process in water, chlorinated tablets exist almost entirely in the form of hypochlorous acid (HClO). Hypochlorous acid, a powerful oxidizing agent, kills bacteria by oxidatively degrading the proteins of pathogens. Experiments have shown that, at the same concentration, the bactericidal ability of hypochlorous acid is far greater than that of hypochlorites (such as sodium hypochlorite and calcium hypochlorite). The unique molecular structure of chlorinated disinfectants allows them to gradually decompose in water, releasing stable hypochlorous acid that other disinfectants cannot provide.
Ease of Use:
3.Compared to TCCA, which needs to be made into a solution, chlorinated tablets can be directly added to the swimming pool and fully dissolve within about 10 minutes, greatly simplifying the disinfection process. When adding the tablets, open the circulation system to evenly disperse the solution in the water, enhancing the sterilization efficiency. If combined with an automatic dosing device, the operation process becomes even more streamlined, achieving more precise control.
Proper Dosage and Application Control
The required amount of disinfectant should be determined based on the pool’s capacity and current water quality conditions. Generally, disinfecting the water with 1 to 3 grams of chlorinated tablets per cubic meter of water can achieve good bactericidal effects. For new water or pools that haven’t been used for a long time, the initial disinfection dosage may be larger.
Add the measured disinfectant directly to the pool. To ensure even distribution of the medicine in the water, it should be evenly sprinkled across the surface. In larger pools, automatic or semi-automatic dosing devices can be used to ensure even and quantifiable distribution of the solution.
pH Level Checking:
Before and after adding the disinfectant tablets, check the pH level of the pool water to ensure it is within the ideal range (usually 7.2 to 7.8) for effective disinfection. After adding the disinfectant, wait for a while (usually 30 minutes to 1 hour) to allow the medicine to fully dissolve and take effect.
From the above research, it is evident that chlorinated disinfectants have many advantages in the swimming pool water environment. They not only effectively kill bacteria and viruses in the water but also are favored for their convenience, economical practicality, and ease of use. However, to prevent adverse effects on swimming equipment and athletes’ health, it is essential to correctly select and use chlorinated tablets while ensuring effective sterilization. From various perspectives, chlorinated disinfectants are an excellent choice for swimming pool water environment management.
