With the improvement of people’s requirements for health and quality of life, swimming has become a popular sport. However, the safety of swimming pool water quality is directly related to the health of users, so swimming pool disinfection is an important link that cannot be ignored. This article will introduce the main classification of swimming pool disinfectants and their optimal application scenarios to help readers better choose and use suitable products.
Main classification of swimming pool disinfectants
Swimming pool disinfectants are mainly divided into the following categories:
1. Chlorine-based disinfectants
Chlorine-based disinfectants are the most widely used swimming pool disinfection products at present, mainly including the following:
- Trichloroisocyanuric Acid (TCCA)
Trichloroisocyanuric acid is a highly efficient and stable chlorine-based disinfectant with excellent bactericidal effect and long stability, suitable for outdoor swimming pools.
- Sodium Dichloroisocyanurate (SDIC)
This disinfectant dissolves quickly and can be used as a pool shock. It is suitable for scenarios that require rapid treatment, such as emergency disinfection or swimming pools with poor water quality.
Calcium hypochlorite has strong oxidizing ability and dissolves quickly. But attention should be paid to safe storage and transportation.
2. BCDMH （ Bromochlorodimethylhydantoin）
Bromochlorodimethylhydantoin can continuously release active Br and active Cl by dissolving in water to form hypobromous acid and hypochlorous acid. The generated hypobromous acid and hypochlorous acid have strong oxidizing properties and oxidize the biological enzymes in microorganisms to achieve the purpose of sterilization.
3. Ozone
Ozone is a powerful oxidant that can effectively kill microorganisms and is suitable for high-end swimming pools and spas.
4. Ultraviolet disinfection
Ultraviolet technology kills bacteria by destroying the DNA of microorganisms, but it needs to be used in conjunction with other disinfectants to maintain the residual disinfection ability in the water.
The best disinfectant selection in different scenarios
The choice of disinfectant should be different depending on the usage scenarios and conditions of the swimming pool.
1. Family swimming pool
Family swimming pools are usually small in size and have limited frequency of use, so a disinfectant that is simple to operate and safe to store should be selected.
-Recommended products: trichloroisocyanuric acid tablets or sodium dichloroisocyanurate granules.
- Reasons:
- Easy to control the amount of release.
- Good continuous disinfection effect and reduced maintenance frequency.
- Cyanuric acid components can effectively protect the activity of chlorine.
2. Outdoor public swimming pools
Outdoor public swimming pools are frequently used and have a large flow of people, requiring efficient and economical disinfection solutions.
- Recommended products:
- Trichloroisocyanuric acid (suitable for daily maintenance).
- SDIC and (suitable for rapid adjustment during peak periods).
calcium hypochlorite with cyanuric acid
- Reasons:
- Stable chlorine release capacity meets high load requirements.
- Relatively low cost, suitable for large-scale application.
3. Indoor swimming pools
Indoor swimming pools have limited ventilation conditions, and the volatilization of chlorine may cause health problems, so low-volatility or non-volatile products need to be selected.
- Recommended products:
- Calcium hypochlorite.
- SDIC
- Non-chlorine disinfectants (such as PHMB).
- Reasons:
- Reduce chlorine odor and irritation.
- Maintain cleanliness while improving user experience.
4. Spas or high-end swimming pools
These places focus on water purity and user experience, and usually choose more environmentally friendly and efficient solutions.
- Recommended products: SDIC, BCDMH, ozone
- Reasons:
- Highly effective sterilization while reducing chemical residues.
- Improve user comfort and trust.
5. Children’s swimming pools
Children’s swimming pools need to pay special attention to low irritation and safety.
- Recommended products:SDIC, PHMB
- Reasons:
- Chlorine-free disinfectants can reduce irritation to the skin and eyes.
- Ultraviolet light reduces the formation of harmful by-products.
Precautions for swimming pool disinfection
When selecting and using disinfectants, you should also pay attention to the following points:
1. Follow the product instructions
The dosage and usage methods of different disinfectants vary. You must strictly follow the instructions to avoid overdosage or underdosage.
2. Monitor water quality regularly
Use pool test strips or professional testing equipment to regularly check the pH value, residual chlorine concentration and total alkalinity in the water to ensure that the water quality meets the standards.
3. Prevent mixing of chemicals
Different types of disinfectants may react chemically, so compatibility must be confirmed before use.
4. Safe storage
Disinfectants should be stored in a dry, well-ventilated place, away from high temperatures and direct sunlight, and out of the reach of children.
The selection and use of pool disinfectants are the key to maintaining pool water quality. Choosing the right disinfectant according to the needs of different scenarios can not only effectively ensure water quality safety, but also reduce maintenance costs and improve user experience.
