What Are The Methods Of Using Industrial Circulating Water Disinfectants?

The dosing of bactericides in industrial circulating water systems must follow standardized procedures to ensure treatment effectiveness and maintain stable system operation. The general operating procedures are as follows:

I. System Pretreatment
Before adding the bactericide, the circulating water system should be thoroughly cleaned to remove scale, biofilm, and impurities from pipes, heat exchangers, etc. Appropriate cleaning agents and processes should be selected based on the system's contamination level.

II. Chemical Preparation and Dosing
1. Before dosing, the bactericide should be fully dissolved and stirred evenly to form a homogeneous solution.

2. Accurately calculate the required dosage based on the system's water volume and the target concentration (usually 50–100 mg/L).

3. Slowly inject the solution into the circulating water system using a dosing pump or dedicated dosing device, ensuring even distribution in the water.

III. Operation Control and Monitoring
1. After dosing, maintain normal system circulation to ensure the bactericide fully contacts and inhibits microorganisms.

2. Key indicators such as residual chlorine, pH, and total bacterial count need to be monitored regularly. The dosing frequency and dosage should be adjusted according to water quality changes and seasonal characteristics (such as high temperatures in summer or water quality deterioration). If necessary, the frequency can be increased to once a week or the concentration can be increased.

3. It is recommended to establish daily records to track the sterilization effect and system status.

IV. Precautions for Co-treatment Bactericides are often used in combination with water treatment agents such as corrosion inhibitors and scale inhibitors. Compatibility tests should be conducted before mixing to avoid adverse reactions such as precipitation, decomposition, or mutual cancellation between agents, ensuring the synergistic effectiveness of the overall treatment plan.

V. Safety and Operating Procedures Operators must wear appropriate protective equipment; agents should be stored in a cool, ventilated place; waste packaging and residual agent solution must be disposed of in accordance with environmental protection requirements.

Through scientific agent dosing and system management, the proliferation of microorganisms in the circulating water system can be effectively controlled, ensuring the long-term stable operation of equipment and improving water resource utilization efficiency.
