Necessity of compulsory courses for classification of water purifier filter elements

At present, there are various brands of water purifiers on the market. If you look closely at the description of water purifiers, you will always see the terms microfiltration, nanofiltration, ultrafiltration, and reverse osmosis. Remind the public not to let all kinds of filters get dizzy, but to recognize the scientific concept of water purifier consumption. Special classification instructions for water purifier filter elements: Microfiltration (also called coarse filtration): It is simple filtration. The filter element material is generally treated with PP cotton filter element and quartz sand, granular or compressed activated carbon filter element, or KDF particles. The pore size of the microfiltration membrane is generally 0.5-1 micron, which can only filter visible impurities such as sediment, rust, colloid, and large bacterial clusters. The water treated by the microfiltration membrane can only be sensory clear, and cannot be used as qualified drinking water. It is a simple filter device commonly seen in the market. Ultrafiltration (referred to as UF): also known as hollow fiber, is a physical screening process that uses the pore size of ultrafiltration membranes to separate liquids; the pore size is generally 0.1-0.01 microns, and in water treatment, it can mainly filter bacteria, viruses, carbon powder and other macromolecular organics, but cannot effectively remove low-molecular organics such as pesticides, herbicides, detergents, heavy metals, and harmful substances such as iron and manganese ions generated during the transportation of tap water; in general, ultrafiltration pore size The water purified by ultrafiltration water purification products that reach 0.01 microns can meet the standard of direct drinking, but the overall filtration effect and water quality taste are not good. Ultrafiltration membrane The membrane filtration method with pressure difference as the driving force is ultrafiltration membrane filtration. Ultrafiltration membranes are mostly made of acetate fibers or polymer materials with similar properties. It is suitable for the separation and concentration of solutes in the treatment solution, and is also commonly used in the separation of colloidal suspensions that are difficult to complete by other separation techniques, and its application fields are constantly expanding. Nanofiltration (NF for short): The pore size of the nano filter element is between 0.01-0.001 microns; it can filter out chemical pollutants such as antibiotics, hormones, pesticides, petroleum, detergents, heavy metals, algal toxins; and minerals smaller than this pore size Ions can pass through; effectively retain beneficial minerals. Reverse osmosis (referred to as RO): use a special high-pressure water pump to increase the pressure of the raw water, so that the raw water permeates through the reverse osmosis membrane with a pore size of only 0.0001 microns under the action of pressure. Chemical ions, bacteria, fungi, and virions cannot pass through, and are discharged with wastewater. Only pure water molecules with a volume of less than 0.0001 microns are allowed to pass through, that is, pure water. It does not contain minerals that are beneficial to the human body, and it is not good for the human body to drink it for a long time.
