What Are The Technical Characteristics Of Ultrafiltration Membrane Package?
With the development of water treatment technology in China, the filtration function of ultrafiltration membrane has been greatly improved. So far. As long as the occupation involving filtration equipment and process can basically use ultrafiltration membrane.
The application scope of ultrafiltration membrane involves water treatment in almost all occupations in China, such as separate bacteria, heat sources, colloids, suspended magazines and macromolecular organics in industrial water; Terminal treatment for the preparation of pure water and ultrapure water in drinking water; It can be used to separate drinking water and mineral water purification in drinking water, and can also be used for concentration, purification and purification in fermentation, enzyme preparation industry and pharmaceutical industry; Juice concentration and separation; Separation, concentration and clarification of soybeans, dairy products, sugar industry, liquor, tea juice and vinegar; Purification and recovery of industrial wastewater and daily sewage; Recovery of electrophoretic paint and other occupations. It can be seen that the role of ultrafiltration membrane is very extensive.
Ultrafiltration is the process of using a ultrafiltration membrane with an aperture of 1 to 20 nm to filter the solution containing macromolecules or fine particles and separate macromolecules or fine particles from the solution, which is called ultrafiltration. It takes the pressure difference on both sides of the membrane as the driving force and the ultrafiltration membrane as the filter medium. Under a certain pressure, small molecular solutes and solvents pass through the ultrafiltration membrane with a certain aperture, so that macromolecular solutes cannot pass through and remain on one side of the membrane, so as to achieve the purpose of purification, separation and concentration of the solution. It is mainly used to intercept polymer solutes. For example, it is used to treat the feed liquid without solid components, during which the solute and water with relatively small molecular weight penetrate the membrane, while the solute with relatively large molecular weight is intercepted.
With the development of membrane technology and large-scale production, the function of Ge ultrafiltration RO membrane is more stable, and the cost of paper membrane is greatly reduced. At present, ultrafiltration membrane has been widely used in many aspects, such as drinking water purification, industrial water treatment, beverage, biology, food, medicine, environmental protection and so on.
