Trichloroisocyanuric Acid — An Indispensable Water Treatment Chemical for Industry

In the field of industrial water treatment, Trichloroisocyanuric Acid (TCCA) is a widely applicable treatment chemical. Thanks to its high available chlorine content and good stability, it is used in circulating cooling water, industrial wastewater, process water and other stages.

1. Bactericidal and Algae Control in Circulating Cooling Water

Industrial circulating cooling water systems operate continuously, and bacteria, fungi and algae can easily proliferate, forming biofouling that attaches to heat exchangers and pipe walls, reducing heat exchange efficiency and potentially causing under-deposit corrosion. TCCA can be used as a bactericidal and algae-control agent to inhibit microbial growth and improve system operation.

2. Disinfection of Industrial Wastewater

Some industrial wastewater requires disinfection before discharge to reduce microbial indicators. The hypochlorous acid produced by TCCA hydrolysis has broad-spectrum bactericidal capability and can be applied to such disinfection stages.

3. Process Water and Cleaning Water Treatment

In the textile, paper and food processing industries, process water and equipment cleaning water need to be sterilized to reduce the impact of microorganisms on product quality. TCCA can be used for disinfection in these scenarios.

4. Key Points of Use

• Dosage should be determined by water volume, system operating conditions and target residual chlorine. A bench test is recommended first.
• Pay attention to compatibility with other water treatment chemicals such as scale and corrosion inhibitors to avoid interference.
• Strong oxidizing agents are corrosive to some metal materials, so equipment materials and dosing methods should be considered.
• Storage and handling should comply with the product Safety Data Sheet (SDS).

In summary, TCCA has broad applicability in industrial water treatment. Proper selection and standardized dosing are key to realizing its effectiveness and ensuring stable system operation.
