Reverse osmosis scale inhibitor is a chemical agent used in reverse osmosis water treatment systems, mainly used to prevent and reduce membrane surface fouling and pollutant deposition. Their main functions include:
Preventing scaling: After prolonged use, reverse osmosis membranes can form scaling due to dissolved substances in water, which can reduce membrane flux and efficiency. Reverse osmosis scale inhibitors can prevent the formation of scale by chemical reaction or physical adsorption with scaling substances, thereby maintaining the performance of the membrane.
Inhibition of pollutant deposition: Water contains various organic and inorganic pollutants, which can cause blockage of membrane pores, reduce flux, and increase cleaning frequency when deposited on reverse osmosis membranes. Reverse osmosis scale inhibitors can reduce the deposition of pollutants on the membrane surface through chemical reactions or physical adsorption, thereby extending the service life of the membrane.
Cleaning the membrane surface: Reverse osmosis scale inhibitors can also be used as chemical agents to clean the membrane surface. After long-term use, a certain amount of dirt will accumulate on the surface of the membrane, affecting its performance. Reverse osmosis scale inhibitors can clean the membrane surface and improve the efficiency of the system by removing dirt and restoring membrane flux.
In summary, reverse osmosis scale inhibitors play a role in preventing scaling, reducing pollutant deposition, and cleaning membrane surfaces in reverse osmosis water treatment systems, helping to improve the performance of water treatment systems and extend the service life of membranes.
