A comprehensive analysis of the difference between circulating water scale inhibitor and reverse osmosis scale inhibitor?



Those who have experienced dry water treatment know the systems used in industrial water treatment. The circulating water system is to send cooling water (sea water) to the high and low pressure condenser to cool the exhaust steam of the low pressure cylinder of the steam turbine, so as to maintain the vacuum of the high and low pressure condenser, so that the soda circulation can continue. Water is also supplied to open water systems and ash flushing systems. Circulating water scale inhibitor mainly reacts with calcium and magnesium salts in water through chemical reaction to generate water slag precipitation, which is discharged out of the circulating water system through sewage discharge to reduce calcium in water. The concentration of magnesium ions makes it impossible to scale.




Reverse osmosis system is composed of reverse osmosis membrane (RO), high pressure pump and security filter set to protect the RO membrane. Using special high pressure pump, raw water is added to the pressure of 6-20 kg, so that raw water seep through the RO membrane with a diameter of only 0.0001 micron under the action of pressure. Chemical ions and bacteria, fungi, and virions cannot pass through, and are discharged with the wastewater. Only water molecules and solvents smaller than 0.0001 micron are allowed to pass through. After dissolving in water, reverse osmosis scale inhibitor ionizes and generates electronegative molecular chains. It forms water-soluble complexes or chelates with Ca2+, thus increasing the solubility of inorganic salts and playing a role in scale inhibition. At the same time, some functional groups in the reverse osmosis scale inhibitor molecules occupy a certain position on the crystal nuclei or microcrystals of inorganic salts, which hinders and destroys the normal growth of inorganic salts, slows down the growth rate of crystals, and thus reduces the formation of salt scale.




Secondly, the product raw materials are not the same. The circulating water scale inhibitor mostly uses acrylic acid - acrylic ester copolymer, organic phosphorus, zinc salt, and other industrial raw materials. The reverse osmosis scale inhibitor uses natural dispersant, phosphonic acid, phosphonic acid, phosphonic acid and high polymer quality raw materials.




Therefore, reverse osmosis scale inhibitor is different from circulating water scale inhibitor and corrosion inhibitor, so it cannot be used as a substitute. If the reverse osmosis system is added with circulating water scale inhibitor and corrosion inhibitor, the reverse osmosis membrane components will be directly blocked, and the membrane components will be scrapped and the loss will be incalculable. Please pay attention to this. Finally, the price of reverse osmosis scale inhibitor is much higher than that of corrosion and scale inhibitor. Usually, the price of reverse osmosis scale inhibitor is 20,000 yuan/ton, and the imported price is higher, while the circulating water corrosion and scale inhibitor is much cheaper.




Scale inhibitor is an important member of circulating water reagent and reverse osmosis reagent, plays a pivotal role in the system operation, and is an essential protector for the normal operation of the system.
