SODIUM DI CHLOROISOCYANURATE
SDIC available in granular, powder, and tablet forms. It releases active chlorine when dissolved in water, making it suitable for disinfection and microbial control in swimming pools, industrial water systems, wastewater treatment, sanitation, and other applications.
Sodium Dichloroisocyanurate (SDIC), also known as Sodium Dichloro-s-triazinetrione, is a widely used chlorine-based disinfectant and water-treatment chemical. It is valued for its high available chlorine content, good water solubility, and effectiveness against a broad range of microorganisms.
Sodium Dichloroisocyanurate (SDIC) – Product Overview
Sodium Dichloroisocyanurate is commonly available in granular, powder, and tablet forms. It releases active chlorine when dissolved in water, making it suitable for disinfection and microbial control in swimming pools, industrial water systems, wastewater treatment, sanitation, and other applications.
Sodium dichloroisocyanurate is the sodium salt of a chlorinated hydroxytriazine and is used as a source of free available chlorine, in the form of hypochlorous acid, for the disinfection of water. It is widely used as a stable source of chlorine for the disinfection of swimming pools and in the food industry.
Major Applications
1. Swimming Pool Water Treatment
SDIC is widely used for maintaining microbiological control in swimming pools, spas, and recreational water systems.
2. Drinking Water & General Water Disinfection
Appropriately specified SDIC grades can be used for water disinfection where permitted by applicable regulations and treatment standards.
3. Industrial Water Treatment
It is used for controlling microorganisms, algae, and biofilm in selected industrial water systems.
4. Wastewater Treatment
SDIC can be used as a chlorine-based disinfectant in wastewater treatment processes to reduce microbial contamination.
5. Marine & Shipboard Applications
SDIC is used in selected marine sanitation and water-treatment applications, subject to the vessel's treatment system and operating requirements.
6. Institutional & Surface Disinfection
Suitable formulations are used for sanitation and disinfection of hard surfaces, equipment, and facilities.
SDIC disinfectant (powder/granular/tablet) provides fast active chlorine control for swimming pools, drinking water, industrial systems, wastewater, marine sanitation, and institutional surface disinfection.
Sodium dichloroisocyanurate possible to use as a disinfectant for drinking-water in emergency situations, and for routine use in some water supplies.
