Sodium dichloroisocyanurate for swimming pool disinfection

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
