Reverse osmosis scale inhibitors and circulating water scale inhibitors are two different types of scale inhibitors, with some differences in application scenarios and mechanisms of action:
Application scenario:
Reverse osmosis scale inhibitor: mainly used in reverse osmosis (RO) systems for water quality treatment in processes such as seawater desalination and pure water preparation. It helps reduce the formation and blockage of scale layers on the surface of reverse osmosis membranes, and improves the operational efficiency and lifespan of RO systems.
Circulating water scale inhibitor: mainly used in industrial circulating water treatment such as circulating cooling water systems and boiler water systems, to prevent the generation and accumulation of scale and maintain the normal operation of the circulating water system.
Mechanism of action:
Reverse osmosis scale inhibitor: Reverse osmosis scale inhibitor prevents salt and other solid particles from crystallizing and depositing on the surface of the reverse osmosis membrane by inhibiting the crystallization of dissolved substances in water or slowing down the crystallization rate, thereby reducing membrane blockage and scale formation.
Circulating water scale inhibitor: Circulating water scale inhibitors form stable complexes or soluble salts by combining with hardness ions (such as calcium, magnesium, etc.) in water to prevent the formation and deposition of hard scale. In addition, circulating water scale inhibitors can also inhibit the formation of scale layers by chelating, dispersing, or changing the pH value of the water body.
It should be noted that the specific formulas and usage methods of reverse osmosis scale inhibitors and circulating water scale inhibitors may vary depending on different application requirements and system conditions. When selecting and using scale inhibitors, reasonable selection should be made based on specific circumstances, and the correct use should be carried out according to the product manual or professional guidance.
