Using modified PAN material, the ultrafiltration membrane has outstanding separation performance, good oxidation resistance, thermal stability, good mechanical properties, and permanent hydrophilicity. Despite the advantages mentioned above, the disadvantage is that the anti-pollution performance is slightly worse. For this reason, we overcome the above shortcomings by modifying the materials and membranes, and making their performance more excellent. Membrane filament has high strength and a breakage rate of less than three thousandths:
Unique central pipe bracket with uniform filament distribution and smooth water flow can prolong the service life of the membrane filament; reliable performance, water washing, and medication washing will not affect the normal use of the membrane. According to the water quality conditions, full filtration and cross-flow filtration can be selected. Full-volume filtration has the advantages of energy saving and high water utilization rate; cross-flow filtration can discharge pollutants in time, reduce the times of membrane cleaning, and prolong the service life of membrane components. Compared with traditional filtration methods, this system has the advantages of high automation, small floor area (only 1/2 of traditional filtering methods), high filtration accuracy, unattended, and it is a good option for reverse osmosis pretreatment.
It is mainly used in various fields of industry, such as pure water, boiler recharge water, food processing and pharmaceutical manufacturing.

PAN UF membranes are widely used in applications including:
Runmo provides reliable ultrafiltration membrane solutions for different industrial filtration requirements.
PAN material provides excellent mechanical strength, oxidation resistance, and thermal stability, making it suitable for long-term operation in industrial filtration systems.
Compared with other membrane materials, PAN UF membranes offer stable filtration performance and reliable durability for demanding water treatment applications.
Both PAN UF membranes and PVDF UF membranes are used for ultrafiltration applications, but they have different material properties.
PAN membranes provide excellent mechanical strength and filtration stability, while PVDF membranes are known for strong chemical resistance and cleaning tolerance.
The choice between PAN and PVDF UF membranes depends on feed water quality, operating conditions, and application requirements.

Polyvinylidene fluoride (PVDF) is used as the material, and its greatest characteristic is its high chemical stability. The chemical stability determines its outstanding antioxidant ability and acid and alkali resistance.
In order to ensure the normal operation of membrane components and stabilize water flux, it is necessary to clean the membrane regularly. The most effective method is oxidant cleaning. But oxidants can damage the membranes. The ability of polyvinylidene fluoride (PVDF) to withstand oxidants (sodium hypochlorite, etc.) is more than 10 times that of polyethersulfone, polysulfone, and other materials, thus greatly prolonging its service life. Polyvinylidene fluoride (PVDF) film also has strong flexibility. The results of the practical case investigation show that the PVDF film has the advantage of a minimum breakage rate. It has been more and more widely used in the field of sewage treatment. Sketch of characteristics of Runmo PVDF membrane module :
1. High antioxidant and cleaning resistance: High-quality polyvinylidene fluoride material determines the enhanced chemical stability of membrane products, and the high chemical stability of the membrane makes the membrane resistant to high concentration oxidant cleaning, thus effectively preventing microbial reproduction such as bacteria;
2. High Flux: High Porosity of Products, High Flux of Components;
3. High Strength: Good flexibility: Membrane wire has high strength and good flexibility. It is not easy to break during cleaning;
4. High pollution resistance: through hydrophilic modification, the product's pollution resistance is greatly improved;
5. Good Water quality : Ultrafiltration membrane has a small nominal aperture, so it can remove almost all suspended particles, microorganisms, colloids, pathogens and bacteria in the application of this product;
6. Long service life: Components usually adopt external pressure structure which is not easy to plug. They have larger filtering area and higher pollution interception, easy to clean, and more thorough. They can remove the fouling on the membrane surface in time, so that the service life of the membrane is longer.
