What is used for swimming pool disinfection?
This is a problem that many swimming pool managers are struggling with. If no treatment agent is used, the pool water will need to be replaced frequently, otherwise germs will easily breed, and a layer of slippery and dirty microbial algae will adhere to the pool wall. May emit an unpleasant odor. So what? Swimming pool sterilization and disinfectant can be said to be an essential protective measure for swimming pools. People are paying more and more attention to the water quality and environment of swimming pools. According to market demand, our company has developed several formulas for swimming pool sterilization, including sodium dichloroisocyanurate for swimming pool disinfection: Wide organic chlorine disinfectant, containing 60% to 64.5% available chlorine, has the advantages of high efficiency, broad spectrum, stability, high solubility and low toxicity. As a swimming pool sterilizing and disinfecting solution, an aqueous solution can be used for spraying, soaking, and wiping. The usage is the same as that of bleaching powder. Mixed with paraformaldehyde dry powder and ignited, the gas can be fumigated and sterilized. It is used for disinfection of swimming pool changing rooms, swimming tools and towels used by swimmers, etc.
Sodium dichloroisocyanurate (SDIC) is a common chemical used in swimming pools as a disinfectant and sanitizer. It is a type of chlorine compound that is effective at killing bacteria, viruses, and other harmful microorganisms that can be found in swimming pool water.
When SDIC is added to water, it dissolves and releases chlorine, which then reacts with contaminants in the water to destroy them. It is often used in conjunction with other chemicals like pH balancers and algaecides to maintain the proper balance of chemicals in the water.
How to dilute sodium dichloroisocyanurate?
Dissolve in warm water first, then dilute with water.
Sodium dichloroisocyanurate powder is a white powder or granular solid, which is a broad-spectrum, high-level, and low-toxicity disinfectant among oxidative fungicides. Generally, this substance is commonly used in clinical practice to sterilize instruments, such as gastroscopes, colonoscopes, and catheters, as well as to clean operating panels. Now swimming pools often use this substance to sterilize.
Because the toxicity of sodium dichloroisocyanurate is relatively low, but the dust is irritating to the nose and throat, and inhalation of high concentrations can cause bronchospasm.
SDIC is available in granular or tablet form, and it is important to follow the manufacturer's instructions carefully when using it. Overuse can lead to an excess of chlorine in the water, which can cause skin and eye irritation, as well as damage to pool equipment and surfaces.
Disinfection principle of sodium dichloroisocyanurate
Sodium dichloroisocyanurate, also known as Youchlorojing, is a white crystalline powder with a strong chlorine smell, containing 60% to 64.5% of available chlorine, stable in nature, and its available chlorine content decreases by 0.16% after half a year of indoor storage. It is easily soluble in water, the solution is weakly acidic at 25°C, and the pH of its 1% aqueous solution does not exceed 6.4. Dissolved in water to produce hypochlorous acid, poor stability in aqueous solution. As the temperature rises or the time prolongs, the loss rate of available chlorine increases.
Sodium dichloroisocyanurate usage and dosage
An appropriate amount of sodium dichloroisocyanurate is used for disinfection, which can achieve the desired effect without causing waste of materials.
Cleaning the pond: Splash the whole swimming pool with a concentration of 10-15 g/m3.
The dosage of chlorine in the swimming pool is 1 kg of chlorine for every increase of 1PPM1000 tons of water in the residual chlorine content. The content of sodium dichloroisocyanurate is about 60%, that is, 1/0.6=1.6 kg.
Due to chlorine volatilization consumption and other factors, the daily dosage of 1000 tons of water is about 3-5 kg.
The international standard is to maintain residual chlorine at 0.3-0.5.
Pay attention to the use of sodium dichloroisocyanurate
Store sodium dichloroisocyanurate in a dry and ventilated place.
It cannot be used concurrently or mixed with acid-base drugs.
Sodium dichloroisocyanurate should be prepared and used immediately.
The toxicity of sodium dichloroisocyanurate should be controlled at the lower limit of the effective dose when the water temperature rises.
It is also important to store SDIC in a cool, dry place, away from other chemicals, and to keep it out of the reach of children and pets. Additionally, it is recommended to wear protective gloves and goggles when handling SDIC to avoid contact with skin or eyes.
Sodium dichloroisocyanurate can quickly kill viruses, bacteria and their buds, and can effectively prevent hepatitis and other infectious diseases. Make your swimming pool and bathroom have a fresh and clean environment
Overall, when used properly, SDIC can be an effective and convenient way to keep swimming pool water clean and safe for swimmers.
Q: What is Sodium Dichloroisocyanurate (SDIC)?
A: Sodium Dichloroisocyanurate (SDIC) is a chemical compound commonly used as a disinfectant in swimming pools and water treatment systems. It contains chlorine and cyanuric acid, making it an effective way to sanitize water.
Q: How does SDIC work for swimming pool disinfection?
A: When SDIC is dissolved in water, it releases chlorine, which acts as a powerful disinfectant. The chlorine effectively kills bacteria, viruses, and other microorganisms present in the pool water, helping to maintain a safe and clean swimming environment.
Q: Is SDIC suitable for all types of pools?
A: SDIC is commonly used in a variety of pool types, including residential and commercial pools. However, its usage might vary depending on the pool size, usage frequency, and water conditions. It's recommended to consult with a pool professional to determine the appropriate dosage for your specific pool.
Q: How is SDIC added to a swimming pool?
A: SDIC is usually available in granular or tablet form. Granules can be broadcasted directly into the pool water, while tablets can be placed in a pool skimmer, floater, or chlorinator. It's important to follow the manufacturer's instructions for the proper dosage and application method.
Q: What is cyanuric acid, and why is it in SDIC?
A: Cyanuric acid is a stabilizer that helps to protect chlorine from degradation due to sunlight (UV rays). When added to the pool, cyanuric acid forms a protective layer around the chlorine molecules, extending their lifespan and effectiveness. SDIC contains both chlorine and cyanuric acid, making it a convenient all-in-one product.
Q: How often should SDIC be added to a pool?
A: The frequency of SDIC addition depends on factors such as pool usage, temperature, and water quality. Generally, chlorine levels should be monitored regularly (ideally daily) and adjusted as needed. Pool professionals often recommend maintaining a free chlorine level of 1-3 ppm (parts per million).
Q: Are there any safety precautions when using SDIC?
A: Yes, there are important safety precautions to consider. SDIC and chlorine-based products should be stored in a cool, dry, well-ventilated area away from direct sunlight and sources of heat. When handling SDIC, it's advisable to wear appropriate protective gear like gloves and goggles. Additionally, never mix SDIC with other pool chemicals directly.
Q: Can SDIC be used in hot tubs or spa pools?
A: SDIC can be used in hot tubs and spa pools, but the dosage and application method might differ from those used in larger swimming pools. It's crucial to carefully follow the manufacturer's recommendations for these smaller water systems.
Q: Are there any alternatives to SDIC for pool disinfection?
A: Yes, there are alternative pool disinfection methods, such as using liquid chlorine (sodium hypochlorite), calcium hypochlorite, bromine-based products, ozone generators, UV sterilizers, and saltwater chlorination systems. Each method has its own pros and cons, and the choice often depends on factors like pool size, maintenance preferences, and local regulations.
