Areas of use, handling and where to get it from.

Sodium Dichloroisocyanurate (SDIC or NaDCC) is a sodium salt derived from chlorinated hydroxy triazine. It’s used as a free source of chlorine in the form of hypochlorous acid commonly used to disinfect water. 

As a stable source of Chlorine, NaDCC is used in the disinfection of swimming pools and sterilization of food. It has been used to purify drinking water in cases of emergencies, thanks to its steady supply of chlorine.  

It’s steadily finding adoption in house-holds for purifying drinking water.

Sodium Dichloroisocyanurate Uses

  •  Fabric Bleaching 

In the fabric sector Sodium Dichloroisocyanurate is used to bleach textiles as well as prevent wool from shrinking. It can also be used to disinfect air and tableware in homes and restaurants. 

  • Medical Field 

As a disinfectant, it has amazing cleaning and sterilization properties. This makes NaDCC suitable for medical purposes. It can be used to disinfect and sterilize hospital equipment for surgical and minor operations. Recent tests have indicated that it can be used in killing Hepatitis A and B viruses. 

  • Science 

NaDCC is used in scientific research to show chemiluminescence. It emits a red light when it is decomposed by concentrated hydrogen peroxide. When concentrated NaDCC is mixed with a diluted copper (II) sulfate solution, it gives an intense lilac precipitate of sodium copper Dichloroisocyanurate. 

  • Swimming Pools 

NaDCC is used for clearing any bacteria, viruses, algae, and any other pathogens from swimming pools. Its slow release of chlorine makes it ideal for such purposes. Since it comes in tablets, handling and using it is simple and easy. 

  • Drinking-Water 

As previously stated, NaDCC has been used in the purification of drinking water in emergency cases. This includes places that have been hit by an earthquake/tornado or experienced extensive flooding. In tablet form, it’s also used to sterilize drinking water in homes. 

  • Farming And Agriculture 

Since NaDCC gradually releases chlorine for a prolonged period of time, it’s also used in farming. Here it is used to kill any microbes off fruits, thereby making it easier to transport produce across lengthy distances. It’s also used in: 

    • Dairy products 
    • Rice seed treatment 
    • Fruit preservation 
    • Animal husbandry 
    • Silkworm rearing 
  • Fishery 

Fish diseases may result in severe losses on the farm. This is mainly in the form of reduced fish growth, fish death, increased feeding cost due to lack of appetite, and increased vulnerability to predators. 

As a water purifier, this compound can completely kill and reduce bacteria and fungi commonly found in circulating water systems. Thus, it can significantly reduce cases of diseases on fish farms. 

Pros Of Using NaDCC  

  • No bad odour after use. 
  • No after-taste in the water. 
  • Easy to handle 
  • Comes in several forms, i.e., tablet and crystallin. 

How To Purchase NaDCC

Currently, the production of NaDCC on a small-scale level isn’t viable. But what you can do is purchase large volumes of the compound and then divide it into smaller portions. 

The material and equipment for such an operation aren’t expensive. With a bit of training, you can comfortably perform this task. Despite not posing a significant danger to humans, ensure to follow safety procedures while handling NaDCC. This includes using gloves in each operation. 

Numerous manufacturers are dealing with the production, selling, and distribution of NaDCC. To get in touch with one, all you need to do is go online and do a quick check. Compare several quotes as well as additional perks such as free shipping before settling on one. 

When not in use, store Sodium Dichloroisocyanurate in watertight containers far from heat sources and humidity.
