Disinfecting swimming pools is crucial for maintaining clean water quality and ensuring the health of swimmers. Bleach is a commonly used and effective disinfectant, and its dosage is key to controlling water quality. This article delves into the optimal ratio of bleach in swimming pool disinfection, providing practical suggestions for pool managers and maintenance personnel to ensure the safety and cleanliness of swimming pool waters, offering visitors a pleasant swimming experience.

The active ingredient in bleaching powder is primarily calcium hypochlorite, which also contains calcium chloride. The low content of calcium hypochlorite in bleaching powder means that, in specific scenarios, larger amounts of bleaching powder may be required to achieve the desired disinfection effect.
In comparison, bleach has a higher calcium hypochlorite content, making it more effective for disinfection. Because it contains more calcium hypochlorite, less bleach is needed to effectively disinfect and clean the water.
Bleach is a white and powdery disinfectant whose main component is a calcium complex salt. The active ingredient is calcium hypochlorite (Ca(OCl)₂). When dissolved in water, this substance produces calcium oxide precipitation and hydrochloric acid, simultaneously releasing new ecological oxygen with powerful bactericidal properties. Bleach plays a crucial role in swimming pool water treatment.
The sterilization mechanism of bleach primarily works by releasing chloride ions in calcium hypochlorite to generate hypochlorous acid, effectively removing harmful microorganisms in the water. Its potent bactericidal power makes bleach a widely used choice for swimming pool disinfection.
However, bleach has some disadvantages. Due to its granular and easily soluble nature, it is relatively inconvenient during storage and transportation. Additionally, bleach leaves residue in the pool water after use, requiring additional treatment steps to ensure the water is clear and transparent.
The proportion of bleach powder
To determine the quality of swimming pool water, choosing the appropriate dosage ratio is essential. The recommended dosage is 20-30 kilograms per 1,000 cubic meters of water. This ratio directly influences the concentration of bleaching water, affecting its sterilization and disinfection effects.
Adding 20 kilograms of bleaching powder is suitable for relatively clean water with very few microorganisms or for daily regular maintenance. This maintains basic sanitary conditions in water bodies without compromising water quality.
Sprinkling 30 kg of bleaching powder is appropriate for crowded water bodies with numerous microorganisms or when a strong bactericidal effect is needed. However, caution is needed to avoid excessive impact on water quality.
Regardless of the amount added, ensure that the bleaching powder is evenly mixed and dissolved in the water to avoid affecting water quality due to uneven concentration. Regularly monitor water quality after release to ensure that the use of bleach does not negatively impact the chemical balance in the water. Considering water conditions, disinfection needs, and economic costs, a reasonable selection of the amount of bleach can help ensure the cleanliness of swimming pool waters and the health of swimmers.
