The dosage of reverse osmosis scale inhibitor depends on multiple factors, including water quality, membrane type, and operating conditions. Generally speaking, the dosage should be adjusted according to the specific situation to ensure the best scale inhibition effect and membrane performance.
Usually, the dosage can be determined according to the following steps:
1. Preliminary determination of drug dosage: Based on the results of water quality analysis, determine the types and concentrations of pollutants that may exist in the water. Based on the performance indicators of the scale inhibitor and the recommended dosage range provided by the manufacturer, the dosage of the agent is preliminarily determined.
2. Conduct small-scale experiments: Before actual operation, conduct small-scale experiments to verify the preliminarily determined dosage of chemicals. Based on the experimental results, evaluate the scale inhibition effect and the water quality after treatment, and further optimize the dosage of the agent.
3. Monitoring and adjustment: During actual operation, regularly monitor water quality parameters and membrane performance, such as water flux, recovery rate, and pressure changes. According to the monitoring results, adjust the dosage of the agent in a timely manner to maintain the ideal scale inhibition effect and membrane performance.
It should be noted that the determination of dosage should comprehensively consider multiple factors such as the characteristics of scale inhibitors, water quality conditions, and operating conditions. It is recommended to communicate with professionals or scale inhibitor suppliers before using scale inhibitors, and determine the optimal dosage based on the specific situation. In addition, when using scale inhibitors, attention should be paid to safe operating practices and comply with relevant legal and regulatory requirements.
