TCCA 90% (Trichlor)
High-purity Trichloroisocyanuric Acid supplying >90% active available chlorine. Available in powder, 8-30 mesh granules, and slow-release 200g tablets for cooling water towers, commercial swimming pools, and sewage disinfection.
Technical Specification Target
Continuous Sanitization & UV Stabilization
Upon dissolving in water, TCCA hydrolyzes into hypochlorous acid (HOCl) and cyanuric acid. Cyanuric acid acts as a natural UV stabilizer, preventing the breakdown of active chlorine by sunlight in outdoor pools and open cooling towers.
The 200g slow-dissolving tablet provides constant, controlled release chlorine residual (1.0 to 3.0 ppm free chlorine) for up to 7 to 14 days per tablet in erosion feeders or skimmers.
Standard Industrial Dosage
| Application | Recommended Dosing |

| Cooling Tower Water Disinfection | 2.0 – 5.0 ppm residual |
| Sewage / ETP Effluent Sanitization | 10.0 – 20.0 ppm |
| Textile Bleaching & Anti-Shrink | 0.5 – 2.0 g/L |

Frequently Asked Questions: TCCA 90% (Trichlor)
Expert technical answers on dosing, chemistry, handling, and application performance.
Q1. What is TCCA 90% and what physical forms are available?
TCCA (Trichloroisocyanuric Acid, CAS 87-90-1) is an efficient dry organic source of available chlorine (≥90.0%). Available in 200g slow-dissolving tablets, 8–30 mesh granules, and fine powder.
Q2. What is the recommended dosing of TCCA in swimming pools and cooling towers?
For swimming pools, 1.5 to 3.0 g/m³ daily maintains free available chlorine at 1.0–3.0 ppm. In cooling towers, erosion feeders maintain 0.5–1.0 ppm continuous residual.
Q3. Why is TCCA preferred over sodium hypochlorite (liquid bleach)?
TCCA has >90% available chlorine, is stabilized with cyanuric acid against UV sunlight breakdown, and does not lose strength during warehouse storage.
