What is Trichloroisocyanuric Acid (TCCA)?
TCCA (Chemical Formula: C3Cl3N3O3) is a white crystalline compound with 90% available chlorine content, making it one of the most potent chlorine-based disinfectants available. Unlike liquid chlorine alternatives, TCCA offers:
- Slow dissolution rate (3-7 days for tablets)
- pH-neutral characteristics when dissolved
- Lower corrosion risk compared to calcium hypochlorite
Industrial & Commercial Applications
1. Swimming Pool Sanitation
200g TCCA tablets are the gold standard for pool maintenance:
| Metric | TCCA Tablet | Liquid Chlorine |
|---|---|---|
| Active Chlorine | 90% | 12-15% |
| Duration | 5-7 days | 24-48 hours |
Case Study: Olympic Pool Maintenance
The Beijing National Aquatics Center reduced chlorine usage by 40% after switching to TCCA tablets, while maintaining 0.5-1.0ppm residual chlorine consistently.
2. Drinking Water Treatment
20g tablets are ideal for emergency water purification:
- Kills 99.99% of bacteria (E.coli, Legionella)
- Effective against viruses including Rotavirus
- WHO-approved for disaster relief operations
Dosage Guidelines
Dissolve 1x 20g tablet per 1,000 liters of water. Wait 30 minutes before consumption.
