Ratio of reverse osmosis scale inhibitor

Reverse osmosis (RO) scale inhibitors are chemical additives used to clean and prevent scale accumulation on the surface of reverse osmosis membranes. The ratio of scale inhibitors needs to be determined based on specific applications and membrane types. The following are common examples of reverse osmosis scale inhibitor ratios in general:

Ratio of phosphite scale inhibitors:

Phosphate based scale inhibitors (such as HEDP, ATMP, etc.): 30-50 ppm

Buffer (such as sodium bicarbonate): 100-200 ppm

Other auxiliary agents (as needed): appropriate amount

Ratio of polyhydroxy acid scale inhibitors:

Polyhydroxy acid scale inhibitors (such as citric acid, acetic acid, etc.): 100-500 ppm

Buffer (such as sodium bicarbonate): 100-200 ppm

Other auxiliary agents (as needed): appropriate amount

Please note that the above ratios are for reference only and are not applicable to all situations. The ratio should be adjusted based on specific water quality, system conditions, and guidelines provided by the manufacturer. In addition, when using scale inhibitors, attention should be paid to safe operation and follow the safety data sheet and instructions provided by the manufacturer. It is best to mix and use under the guidance of professionals.
