The multi-layer filtration system of ultrafiltration pure water equipment is like a layer of checkpoints. According to the different characteristics of complex pollutants in the water, it realizes deep purification of water quality through division of labor, cooperation and coordination.
The first line of defense of the multi-layer filtration system is to intercept larger particles of pollutants in the water. This layer usually uses filter materials with relatively large pores, like a coarse screen, which is specially used to deal with visible impurities in the water. When the water flows into the equipment, large particles such as mud, rust, etc. will be blocked by this layer of filter materials under the action of gravity and water flow impact. These large particles of pollutants cannot pass through the pores of the filter material and can only adhere to its surface. As the water flows, they gradually deposit, thus preventing them from entering the subsequent filtration links, reducing the burden of the subsequent filtration layer, and laying the foundation for the stable operation of the entire filtration system.
Then, the second layer of filtration system begins to play a role, mainly dealing with smaller particles of suspended matter and colloids in the water. Compared with the first line of defense, the pore size of this layer of filter material is finer, which can capture those fine particles that are difficult to detect with the naked eye. Colloids are usually in a stable suspended state in water and are not easy to precipitate naturally. This layer of filter material can adsorb colloidal particles on the surface with its special surface structure and adsorption properties. At the same time, the fine suspended matter remaining in the water will also be intercepted because it cannot pass through smaller pores. After this layer of filtration, the water quality becomes clearer, and the tiny impurities suspended in the water are basically removed.
The third layer of filtration focuses on organic matter and some microorganisms in the water. This layer often uses filter materials with adsorption functions, such as activated carbon. Activated carbon has a rich microporous structure and a huge specific surface area, and has a very strong adsorption capacity. When water flows through this layer, organic pollutants in the water, including humic acid, pesticide residues, detergent residues, etc., will be adsorbed by the micropores on the surface of the activated carbon, and thus separated from the water. At the same time, some smaller microorganisms, such as some bacteria and viruses, will also be captured by the adsorption of activated carbon and cannot continue to move forward with the water flow, further improving the safety and purity of the water quality.
The fourth layer of filtration system focuses on microorganisms in the water, especially bacteria and viruses. The high-precision ultrafiltration membrane in ultrafiltration pure water equipment usually plays a key role in this link. The pore size of the ultrafiltration membrane is extremely small, allowing only water molecules and some small molecules to pass through, while the size of microorganisms such as bacteria and viruses is much larger than the membrane pores, so they will be completely blocked. When the water containing microorganisms passes through the ultrafiltration membrane, the microorganisms can only remain on one side of the membrane and cannot penetrate, thereby achieving effective separation from the water molecules. This filtration method can effectively remove most of the pathogenic microorganisms in the water, providing a reliable guarantee for the safety of drinking water.
The fifth layer of filtration is mainly aimed at odors and some chemicals in the water. Materials with special adsorption properties are used again to adsorb odorous substances remaining in the water. Whether it is the unpleasant odor caused by the decomposition of organic matter in the water or the chlorine smell left by disinfection, it can be effectively adsorbed and removed in this layer, making the purified water taste more refreshing and pleasant. At the same time, for some soluble chemicals, such as some heavy metal ions, this layer of filtration material can also remove them from the water through ion exchange or complexation, further improving the quality of water.
At the final stage of the multi-layer filtration system, there is another fine filtration layer for the final check and optimization of water quality. The pore size of this layer of filter material is the finest, which can capture the extremely small particles and impurities that may be missed by the previous filter layer, ensuring that every drop of water flowing out of the equipment reaches a very high degree of purity. At the same time, this layer can also properly adjust the minerals in the water, retain the mineral elements that are beneficial to the human body, and remove substances that may be harmful to the human body, so that the purified water quality is not only pure, but also healthier and suitable for drinking.
The multi-layer filtration system of ultrafiltration pure water equipment uses each layer of filter material to intercept, adsorb, separate and other functions in turn according to the characteristics of different pollutants. It is like a sophisticated collaborative team to remove complex pollutants in the water in an all-round and multi-level manner. From large particle impurities to tiny microorganisms, from organic matter to chemical substances, each layer performs its own duties and cooperates with each other to ultimately produce pure and healthy drinking water, providing a solid guarantee for people's drinking water safety and quality of life.
