Wholesale TCCA in Bulk: Efficient Disinfection for Water Treatment
Introduction
In an era where water quality management has become paramount across industries, selecting the right disinfection solution is critical for operational efficiency, regulatory compliance, and public health protection. Trichloroisocyanuric Acid (TCCA) has emerged as one of the most reliable and cost-effective disinfectants for water treatment applications worldwide. This comprehensive technical guide explores the advantages of purchasing TCCA in bulk quantities, providing B2B buyers with essential information to make informed procurement decisions.
For water treatment facilities, swimming pool operators, municipal water authorities, and industrial processors, understanding the technical specifications, performance characteristics, and application protocols of TCCA is essential. This article delivers in-depth analysis backed by industry standards and real-world performance data.
1. Understanding TCCA: Chemical Composition and Properties
1.1 Chemical Identity
Trichloroisocyanuric Acid, commonly abbreviated as TCCA, is an organic compound with the following fundamental characteristics:
| Parameter | Specification |
|---|---|
| Chemical Name | Trichloroisocyanuric Acid |
| CAS Number | 87-90-1 |
| Molecular Formula | C₃Cl₃N₃O₃ |
| Molecular Weight | 232.41 g/mol |
| EINECS Number | 201-782-8 |
| Alternative Names | Symclosene, TCICA, Trichloro-s-triazinetrione |
1.2 Physical Properties
TCCA presents as a white crystalline powder or granular solid with distinctive characteristics:
- Appearance: White crystalline powder or granules
- Odor: Characteristic chlorine-like刺激性气味
- Density: 2.191 g/cm³ at 25°C
- Melting Point: 247-251°C
- Solubility in Water: 1.2 g/100g at 25°C
- Solubility in Acetone: 36 g/100g at 30°C
- pH Value (1% Solution): 2.6-3.2
1.3 Chemical Behavior
TCCA functions as a powerful oxidizing and chlorinating agent. Upon contact with water, it undergoes hydrolysis to release hypochlorous acid (HOCl), the active disinfecting species:
C₃Cl₃N₃O₃ + 3H₂O → C₃H₃N₃O₃ + 3HOCl
This controlled release mechanism provides sustained disinfection capability, making TCCA superior to many alternative chlorine sources for extended treatment cycles.
2. Technical Specifications and Quality Standards

| Moisture Content | ≤0.5% | ≤0.8% |
| pH Value (1% Solution) | 2.6-3.2 | 2.6-3.2 |
| Water Insolubles | ≤0.1% | ≤0.2% |
| Particle Size (20-200 mesh) | ≥95% | ≥90% |
