Acid reverse osmosis membrane scale inhibitor is a chemical additive used in reverse osmosis systems, mainly used to prevent and reduce scale accumulation and pollution on the surface of reverse osmosis membranes, in order to maintain the efficient operation of reverse osmosis systems. Its main functions include the following aspects:
Preventing carbonate scale: In reverse osmosis systems, calcium carbonate and other soluble salts in water may deposit on the membrane surface to form scale, known as carbonate scale. The acidic substances in acidic reverse osmosis membrane scale inhibitors can interact with carbonate crystals to inhibit or disperse their deposition, thereby reducing the fouling on the membrane surface.
Inhibition of sulfate scale: In some areas, water sources contain high concentrations of sulfate, which can easily deposit on the surface of reverse osmosis membranes to form sulfate scale. The acidic components in the acid reverse osmosis membrane scale inhibitor can react with sulfate substances such as calcium sulfate, prevent its crystallization and deposition, and prevent blockage of the membrane surface.
Clean the membrane surface: The acidic components in the acidic reverse osmosis membrane scale inhibitor can dissolve and remove pollutants on the membrane surface, such as rust, organic matter, and microbial residues, maintain membrane cleanliness, and improve water flux and desalination efficiency.
PH regulation: Acid reverse osmosis membrane scale inhibitors can regulate and maintain the pH value of water in the reverse osmosis system to meet the working requirements of the membrane. High or low pH values can cause damage to the membrane material, so it is necessary to balance and control the pH value by adding acidic scale inhibitors.
It should be noted that when using acidic reverse osmosis membrane scale inhibitors, it is necessary to follow the manufacturer’s recommendations and instructions for the correct ratio and usage method. At the same time, attention should be paid to the safe operation and storage of chemicals to avoid adverse reactions with other substances, and regular system cleaning and maintenance should be carried out to ensure the long-term stable operation of the membrane.
