Definition of Good ro Membrane by Revers
Updated about August 19, 2019
In today's society, the rapid economic development has led to the continuous deterioration of water pollution, and has also promoted the promotion and popularization of household water purifiers. RO reverse osmosis membrane is the core filter accessory of domestic water purifier. However, in the water purification market, there are many brands of RO membrane, and the quality is good and bad. There are always some inferior RO membranes that make up a small number, thus reducing consumers' sense of experience. Reverse Osmosis Systems Supplier(KOKOELECTRIC) tell everyone what kind of RO membrane can be called a good membrane. Reverse osmosis membrane is, after all, a semi-permeable membrane for filtering impurities. Impurities in water have different sizes, many even exist as ions. These ions are all classified as "salt substances" in chemical concepts. High quality reverse osmosis membrane products can remove these ionic substances. This process is called "desalination". "Desalination Rate" indicates the effect of desalination. Desalination rate of reverse osmosis membrane = (total salt content of feed water-total salt content of produced water)/total salt content of feed water ×100%. The average desalination rate of RO membrane is above 96%. This means that impurities in the water will basically be filtered by ro membrane, and the effluent can be directly drunk. The high desalting rate is related to the membrane element and membrane manufacturing process used in ro membrane. The pore diameter of ro membrane is only 0.0001 micron, which can filter heavy metals, viruses, bacteria, calcium and magnesium ions and other tiny substances that are difficult to remove by common filter elements. At the same time, the application of the roll-type structure makes the ro membrane filter a large amount of water in a unit area to ensure that the water yield meets the actual demand. It is worth noting that the change of desalination rate of reverse osmosis membrane is parabolic. The greater the inlet pressure, the higher the desalination rate. However, after reaching the peak, the desalting rate will not rise again. Therefore, don't blindly pursue too high water inlet pressure. In addition, as the usage time increases, the RO membrane becomes increasingly polluted, the desalination rate will gradually decrease, and the water yield will also decrease. Therefore, attention should be paid to cleaning and replacing the reverse osmosis membrane. Click Reverse Osmosis Systems Manufacturer to learn about more information.
