How does the ultrafiltration water purifier work?

        The ultrafiltration water purifier is a water treatment method that uses the multi-stage filter physics to remove impurities in the water and retain the beneficial trace elements in the water by connecting to the tap water. Many people say that it is equal to having a mineral water plant. Although this statement is a bit exaggerated, it is not unreasonable. The ultrafiltration water purifier is a simple and practical water treatment equipment. Its existence solves many household water problems. As a convenient equipment, ultrafiltration What is the working principle of the water ?
        The type of water purifier is mainly determined by the filter element. Now the filter element of the household water purifier is generally a 4-stage filter or a 5-stage filter. The working principle is to filter the water through the filter element. The first-stage filter is also called PP cotton, the second-stage granular activated carbon, the third stage is precision compressed activated carbon, the fourth stage is reverse osmosis membrane or ultrafiltration membrane, and the fifth grade is post-activated activated carbon.
According to the filter filter series, the degree of purification of water by the water purifier is also very different. The water purifier can filter out impurities, rust and some bacteria in the tap water, but the effect on heavy metals and water alkali is not great. The water purifier can't remove heavy metals and water alkali at all, so the water purifier can meet some of the user's requirements, but it has not reached the standard of direct drinking. It is best to boil it.

         Ultrafiltration is a technology. The main function of this technology is ultrafiltration membrane. In the filtration process, the pressure difference between the two sides of the membrane is used as the driving force, and the ultrafiltration membrane is used as the filtration medium. Under a certain pressure environment, when tap water flows through the surface of the membrane, the dense pores on the surface of the ultrafiltration membrane will intercept the impurities, allowing only small molecules to permeate, and there is about every millimeter of ultrafiltration membrane on the wall of the membrane. With 6 billion 0.01 micron micropores, the pore size allows only water molecules, beneficial minerals and trace elements in the water to pass through, while the smallest bacteria are above 0.02 microns. Rust, suspended matter, sediment, macromolecular organic matter, etc. can be intercepted by the ultrafiltration membrane to achieve the purification process.
Ordinary water passes through the ultrafiltration membrane to become purified water, which can reach the standard of direct drinking, while the ultrafiltration membrane intercepts the pollutants and adsorbs on the inner surface of the filter membrane. This requires the user to periodically rinse the ultrafiltration membrane to avoid pollutants. Blocking the ultrafiltration membrane causes a drop in water production.
