Reverse osmosis scale inhibitor is a chemical agent used in reverse osmosis (RO) systems to reduce and prevent the formation of hardness deposits in water on the RO membrane. Their main functions are:
Preventing the deposition of size molecules: Reverse osmosis scale inhibitors can prevent the formation of large-sized deposits on the surface of RO membranes by coordinating with soluble salt ions in water (such as calcium, magnesium, iron, etc.). These sediments will reduce the efficiency of the RO system and increase energy consumption.
Inhibiting particle aggregation: Scale inhibitors can also inhibit particle aggregation by changing the salt solubility in water and the gravitational interaction between particles. This can prevent particles from depositing on the surface of the RO membrane, thereby maintaining the normal operation of the RO system.
Cleaning and removing existing deposits: Some scale inhibitors also have the ability to remove already formed deposits. They can coordinate or dissolve with sediment to clean the surface of the RO membrane and improve the performance of the RO system.
By using reverse osmosis scale inhibitors, the service life of the RO membrane can be extended, pollution and blockage issues on the membrane surface can be reduced, and the treatment efficiency of the RO system can be improved. However, for different water quality and specific RO systems, it is crucial to choose appropriate scale inhibitors and correct usage methods to ensure optimal performance and long-term stable operation.
