Characteristics of PVDF hollow fiber ultrafiltration membrane

Characteristics of PVDF hollow fiber ultrafiltration membraneIt is a membrane product made from polyvinylidene fluoride (PVDF) as raw material, using advanced thermal manufacturing technology and precision production equipment, and manufactured under strict process conditions. The membrane has the characteristics of small outer diameter and thin inner diameter, and the tube wall is covered with micropores, which can intercept large molecular substances with molecular weights ranging from thousands to hundreds of thousands. This membrane element exhibits separation performance and wide application potential due to its structural design and high-quality material selection. Not only can it efficiently remove harmful substances from wastewater and improve effluent quality, but it can also achieve the recycling of water resources and alleviate the problem of water scarcity. At the same time, this technology also has the advantages of small footprint, high degree of automation, and low energy consumption, which helps to reduce water treatment costs and improve economic benefits.

Characteristics of PVDF hollow fiber ultrafiltration membrane：

1. Good hydrophilicity

Hollow fiber ultrafiltration membranes undergo special hydrophilic treatment, and the membrane fibers have long-term hydrophilic properties. It can have a higher water flow rate at lower water pressure, while improving the fouling resistance of membrane fibers.

2. High filtering accuracy

Hollow fiber ultrafiltration membranes have uniform micropores smaller than 0.1 microns, which can remove microorganisms, colloids, diatoms, and other substances that cause turbidity.

3. Good mechanical strength

The mechanical strength of hollow fiber ultrafiltration membranes reflects the ability of membrane fibers to resist fiber breakage, which causes the membrane to lose its separation performance. This is also an important indicator for evaluating the performance of hollow fiber ultrafiltration membranes.

4. Long lifespan, with excellent resistance to chemical corrosion, oxidation, and photo aging. Therefore, various methods can be used for repeated cleaning to remove pollutants and restore flux.

5. Stable product performance

Starting from the supply of raw materials, preparation processes, and product testing. Ensure stable quality of raw materials, precise control throughout the preparation process, and product testing to ensure stable performance of the product.
