In what fields can SDIC be used?

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.
