The dosage of reverse osmosis scale inhibitor depends on multiple factors, including water quality, scale and design of RO system, operating conditions, and specific scale inhibitor products. Generally speaking, the correct dosage should be determined based on the actual situation, and it is best to follow the following steps:
Determination of initial dosage: Based on the manufacturer’s suggestions or empirical formulas, determine the appropriate initial dosage of scale inhibitor. This is usually calculated based on the production water flow rate, inlet water quality, and expected scale inhibition effect of the RO system.
Monitoring water quality and scale inhibition effect: according to the actual water quality, evaluate the scale inhibition effect by periodically detecting water quality parameters (such as Total dissolved solids, hardness, alkalinity, etc.) and RO membrane performance. Adjust the dosage based on the monitoring results to achieve the expected scale inhibition effect.
Pay attention to moderate dosing: Excessive or insufficient dosing may have adverse effects on the RO system. Excessive dosage may lead to residual scale inhibitors or membrane fouling issues, while low dosage may not provide sufficient scale inhibition effect. Therefore, when adjusting the dosage, attention should be paid to moderate dosing.
Continuous monitoring and adjustment: Regularly monitor the operation status and water quality parameters of the RO system, and adjust the dosage of scale inhibitors in a timely manner according to the actual situation. Over time, adjustments may need to be made based on seasonal, water source changes, or other factors.
It should be noted that the specific dosage should be determined based on the actual situation and the manufacturer’s recommendations. It is best to operate under the guidance of a professional and use the correct amount according to the product manual. Correct and quantitative dosing can maximize the effectiveness of the RO system and extend the service life of the equipment.
