In the vast landscape of disinfection chemicals, choosing the right product can be a complex task for procurement managers, R&D scientists, and formulators. Sodium Dichloroisocyanurate (SDIC) granular stands out as a highly effective and versatile option. As a leading manufacturer and supplier, we often get asked about how SDIC granular compares to other common disinfectants. This guide will help you understand its unique benefits and make an informed decision for your needs.

Understanding the Core of Disinfection: Available Chlorine

Most chlorine-based disinfectants work by releasing hypochlorous acid (HOCl) when dissolved in water. HOCl is the active agent that kills microorganisms. The efficiency and stability of how a chemical releases HOCl significantly differentiate them. SDIC granular, with its typical 56% available chlorine, offers a potent and stable source.

SDIC Granular vs. Other Disinfectants: A Comparative Look

1. SDIC Granular vs. Sodium Hypochlorite (Liquid Bleach):

  • Stability: SDIC granular is far more stable than liquid bleach, which degrades rapidly over time, especially when exposed to heat and light. This means SDIC granular has a longer shelf life and provides more consistent disinfection.
  • Handling and Safety: Liquid bleach is corrosive and prone to splashing. SDIC granular, in its solid form, is safer and easier to transport, store, and dose, minimizing handling risks for personnel.
  • pH Impact: Liquid bleach is highly alkaline, which can affect water pH and require more pH adjustments. SDIC granular has a more neutral impact.
  • Convenience: For many applications, particularly in granular or tablet form, SDIC is more convenient to measure and apply.

2. SDIC Granular vs. Calcium Hypochlorite:

  • Solubility: SDIC granular generally exhibits better and faster solubility compared to calcium hypochlorite.
  • Residue: Calcium hypochlorite can leave behind calcium deposits, especially in hard water areas, which can cloud water or affect equipment. SDIC granular typically leaves fewer solid residues.
  • Stability: While both are relatively stable, SDIC granular often demonstrates superior stability under various storage conditions.

3. SDIC Granular vs. Trichloroisocyanuric Acid (TCCA):

  • Chlorine Content: TCCA typically has a higher percentage of available chlorine than SDIC.
  • Release Rate: TCCA can offer a slower, more prolonged release of chlorine, making it popular for continuous disinfection in pools.
  • Solubility: SDIC granular generally dissolves more quickly than TCCA.
