ultrafiltration membrane It is a special filter membrane, which can filter out macromolecular substances and suspended impurities in water, so as to obtain more pure water. The filtration precision of ultrafiltration membrane is usually 0.01 μ m, which can effectively remove bacteria, viruses, organics, colloidal particles and microorganisms.

Structure and properties of ultrafiltration membrane:

The main component of ultrafiltration membrane is the membrane composed of a variety of polymer materials, which are made by different physical and chemical methods. The pore size of ultrafiltration membrane is usually between 10 nm and 0.1 μ m, which can isolate macromolecular substances and microorganisms. The filtration rate of ultrafiltration membrane depends on the thickness and pore size of the membrane, which is usually 1 to 10 liters/square meter/hour.

Application of ultrafiltration membrane:

1. Water treatment: Ultrafiltration membrane is widely used in water treatment industry, which can remove impurities such as organics, color and odor in wastewater, making water cleaner.

2. Food and beverage processing: Ultrafiltration membrane can be used to extract fruit juice, beer, coffee, tea, etc., to make the final product more transparent, clean and taste good.

3. Medicine and biological products: Ultrafiltration membrane can be used in the production process of bioreactors, vaccines, antibiotics, enzymes and plasma to make the quality of products more pure.

4. Chemical industry: ultrafiltration membrane can be used to produce dyes, resins, solvents, pigments and glues to ensure the purity and quality of products.

Advantages of ultrafiltration membrane:

1. High filtration precision, which can filter out particles, substances and microorganisms of different sizes, making the water more pure.

2. The filtration rate is fast. The filtration rate of ultrafiltration membrane is several times faster than that of traditional membrane, which can improve the production efficiency.

3. Low energy consumption, ultrafiltration membrane can work normally without high pressure or high-speed flow, which can save energy.

4. Easy maintenance, long service life of ultrafiltration membrane, and easy replacement and maintenance.

Development trend of ultrafiltration membrane:

With the improvement of environmental awareness and the progress of industrial technology, people have increasingly high requirements for water treatment industry. Ultrafiltration membrane has become a hot research and application direction in the field of water treatment. In the future, the research focus of ultrafiltration membrane will be on improving filtration speed, broadening application scope, reducing cost and improving product quality. At the same time, ultrafiltration membrane will also be more and more widely used in environmental protection, medicine, industry, life and other fields, bringing more convenience and security to people's lives.
