Sodium Dichloroisocyanurate (SDIC), with CAS No. 2893-78-9, is a versatile chlorine-based disinfectant and oxidizing agent. Its broad-spectrum efficacy makes it applicable in multiple fields:
1. Water Treatment
Drinking Water Disinfection:
Kills bacteria, viruses, and protozoa (e.g., E. coli, Legionella).
Dosage: 1–10 mg/L (residual chlorine ≥0.3 mg/L after 30 mins).
Swimming Pools & Spas:
Alternative to sodium hypochlorite, with slower chlorine release for stable residual protection.
Wastewater Treatment:
Controls algae and biofilms in pipelines.
2. Healthcare & Sanitation
Surface Disinfection:
Hospitals, labs (0.1–0.5% solution for equipment and floors).
Medical Instrument Sterilization:
Compatible with endoscopes when used at 500–1000 mg/L.
Household Sanitizers:
Tablet form for toilet/kitchen disinfection.
3. Food Industry
Fruit & Vegetable Wash:
50–200 mg/L to reduce pathogens (Salmonella, Listeria).
Dairy & Brewery Equipment:
Prevents microbial contamination in processing lines.
4. Agriculture & Aquaculture
Livestock Farming:
Disinfects animal housing (0.05% solution for poultry farms).
Fish Pond Sterilization:
0.2–0.5 mg/L prevents bacterial gill disease.
5. Textile & Paper Industry
Bleaching Agent:
Breaks down dyes and organic residues in wastewater.
Antimicrobial Finishing:
Treats fabrics to inhibit mold/mildew.
6. Emergency Disinfection
Epidemic Control:
Used in disaster zones (e.g., post-flood) for rapid water purification.
WHO-approved for emergency drinking water treatment.
Key Advantages of SDIC
Stability: Longer shelf life than liquid bleach.
Convenience: Tablet/granular forms for controlled dosing.
Cost-Effectiveness: High available chlorine (60–65%).
Note: Avoid mixing with acids (releases toxic chlorine gas) or ammonia (forms chloramines).
For specific applications, consult local regulations (e.g., EPA, WHO) for dosage guidelines.
