TCCA granules and tablets in industrial and pool water treatment applications

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:

Active Chlorine90%12-15%
Duration5-7 days24-48 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.
