Application of NaDCC in Industrial Circulating Water Treatment

Sodium Dichloroisocyanurate (NaDCC or SDIC) is a highly efficient chlorine donor that has been widely used in industrial circulating water treatment. Its strong oxidizing and disinfecting properties make it an indispensable tool for maintaining the quality and efficiency of industrial cooling systems. NaDCC is a stable compound with strong oxidizing properties. It has disinfecting and algae removal effects.

The mechanism of action of SDIC in industrial circulating water treatment

NaDCC works by releasing hypochlorous acid (HOCl) when it comes into contact with water. HOCl is a strong oxidant that can effectively kill a variety of microorganisms, including bacteria, viruses, and algae. Disinfection mechanisms include:

Oxidation: HOCl destroys the cell walls of microorganisms, causing cell death.

Protein denaturation: HOCl can denature proteins and destroy necessary cell functions.

Enzyme inactivation: HOCl can inactivate enzymes and inhibit cell metabolism.

The role of NaDCC in industrial circulating water treatment includes:

Biofouling control: SDIC can effectively prevent the formation of biofilms, which can reduce heat transfer efficiency and increase pressure drop.

Disinfection: Dichloro can disinfect water and reduce the risk of microbial contamination.

Algae Control: NaDCC effectively controls algae growth, which can clog filters and reduce water clarity.

Odor Control: NaDCC helps control odors caused by microbial growth.

Slime Control: NaDCC prevents the formation of slime, which can reduce heat transfer efficiency and increase corrosion.

Specific Applications of Dichloro:

Cooling Towers: Dichloro is widely used to control microbial growth and prevent biofilm formation in cooling towers, thereby improving heat transfer efficiency and reducing energy consumption.

Boilers: By inhibiting the growth of scaling microorganisms, NaDCC helps maintain boiler efficiency and prevent equipment damage.

Process Water: Dichloro is applied in a variety of industrial processes to ensure the quality and purity of process water.

Advantages of Using NaDCC

Efficacy: NaDCC is a strong oxidizing agent that effectively controls microbial growth and biofouling.

Slow Release of Chlorine: The gradual release of chlorine ensures a continuous disinfection effect and reduces the frequency of dosing.

Stability: It is a stable compound that is easy to transport, store and handle.

Economy: It is a cost-effective treatment option.

Safety: SDIC is a relatively safe product when used according to the manufacturer’s instructions.

Ease of Use: Easy to dose and handle.

Precautions

NaDCC is acidic and can corrode certain metal equipment. Therefore, it is important to select the appropriate cooling system construction materials.

While NaDCC is a powerful biocide, it must be used responsibly and in compliance with local regulations. Proper dosing and monitoring are essential to minimize any potential environmental impacts.

Sodium Dichloroisocyanurate has excellent biocidal activity, long-lasting protection, and versatility. SDIC helps improve the efficiency and reliability of industrial cooling water systems by effectively controlling microbial growth and preventing scaling. Consider the potential limitations and safety issues associated with the use of NaDCC. By carefully selecting the appropriate dosage and monitoring water quality, NaDCC can be used to maintain the efficiency and reliability of industrial cooling systems.
