Ultrafiltration is a technology that uses working pressure to promote membrane separation. Ro uf membrane has high removal efficiency for biological macromolecule organic compounds, colloidal solutions, algae, germs, virus infections, toxoids, particulates and other chemical substances. The membrane surface of the ro uf membrane can block impurities in an area with a diameter of 0.002-0.1 μm. According to ultrafiltration technology, biological macromolecules and small molecular water can be separated, thereby purifying water. Ultrafiltration filter is not only simple in steps, but also easy to use, and the protection in the middle and late stages is also very simple.

the principle of ultrafiltration membrane

1. The principle of ultrafiltration membrane

Ultrafiltration is the whole process of membrane separation with screening as the basic separation principle and burden as the driving force. The filtration accuracy is within the range of 0.005-0.01μm, which can effectively remove organic chemicals in water particles, colloidal solutions, bacterial base cushions and polymer materials. It can be widely used for separation, concentration and purification of organic matter. After all, the entire process of ultrafiltration is air conversion. Actual operation at room temperature is especially suitable for the separation of heat-sensitive components. It has excellent high temperature resistance, corrosion resistance, and air oxidation resistance. It can be under 60℃ and PH2-11 standards. Long-term continuous use.

In the entire ultrafiltration process, the solution flows through the membrane surface under the pressure of working pressure, and the organic solvent (water) below the membrane pores and the water permeable membrane of small molecular water solutes become the purification treatment liquid. Solutes and solute units larger than the membrane pores are intercepted and discharged with the flowing water to become extracts. The whole process of ultrafiltration is dynamic filtration, and separation is achieved under fluidity conditions. The accumulation of solutes on the membrane surface is limited, and the ultrafiltration rate attenuation coefficient reaches a certain level, which tends to be balanced, and can be repaired according to cleaning.

2. The main purpose of ro uf membrane

After decades of development trend, ro uf membrane is widely used in chemical plants, biological products, pharmaceutical preparations, clinical medicine, wastewater treatment, food industry, beverage industry, dairy industry, microbial fermentation, biotechnology, waste recycling and other Environmental protection engineering and other industries.
