The dosage of reverse osmosis scale inhibitors is influenced by multiple factors, including water quality, equipment scale, and operating conditions. Generally speaking, it is important to determine the appropriate dosage based on the specific situation.
The following are general guidelines for dosage:
Water quality status: The concentration of soluble salts, hardness substances, and other pollutants in water quality has an impact on the amount of scale inhibitors used. When water contains high concentrations of salts and hardness substances, it may be necessary to increase the dosage of scale inhibitors.
Equipment scale: The scale and processing capacity of reverse osmosis equipment also affect the amount of scale inhibitor used. Larger scale devices typically require the use of more scale inhibitors to maintain their performance.
Operating conditions: Operating conditions such as the operating pressure of the reverse osmosis system and the cleaning frequency of the membrane can also affect the amount of scale inhibitor used. In situations of high operating pressure or frequent cleaning, it may be necessary to increase the amount of scale inhibitor used.
Generally speaking, it is recommended to add the scale inhibitor for the first time according to the recommended dosage provided by the manufacturer, and then adjust it according to the actual situation. The appropriate amount of scale inhibitor can be determined by monitoring the performance indicators of the water treatment system, such as hysteresis pressure, water flux, and turbidity. If there are performance degradation or membrane blockage issues in the water treatment system, it may be necessary to increase the dosage of scale inhibitors.
It should be noted that when using scale inhibitors, the manufacturer’s instructions and safety operating procedures should be followed to ensure correct dosing and control of dosage, in order to maintain the stable operation of the reverse osmosis system.
