TCCA Offers Strong Bactericidal and Bleaching Capability

Trichloroisocyanuric acid (TCCA) is an organic chlorine disinfectant with high available chlorine content and strong oxidizing capability, performing well in both disinfection and bleaching. It is widely used in water treatment and industrial processing.

Bactericidal Capability

TCCA hydrolyzes to produce hypochlorous acid (HClO), which penetrates microbial cell walls and destroys intracellular enzyme systems and protein structures through oxidation, thereby eliminating bacteria, fungi, algae and other microorganisms. Compared with some inorganic chlorine agents, its available chlorine release is relatively steady and its action lasts longer.

Bleaching Capability

Due to its strong oxidizing property, TCCA can oxidize and destroy the chromophoric groups of colored substances, achieving a bleaching effect. It is therefore also used in the bleaching processes of the textile and paper industries.

Common Applications

• Swimming pool disinfection: controlling residual chlorine and inhibiting algae growth.
• Industrial circulating water: bactericidal and algae control in cooling water systems.
• Wastewater treatment: disinfection of industrial and domestic wastewater.
• Textile and paper: bleaching processes and process water sterilization.
• Aquaculture: bactericidal treatment and water quality maintenance.
