PVDF Membranes Electrophoretic paint Hollow Fiber Ultrafiltration Filter UF Membrane

People use PVDF Membrane, or Ultrafiltration membrane, a polymer material membrane, for liquid filtration and separation.

Ultrafiltration membrane is a filter membrane with consistent pore size specs. Its rated pore size ranges from 1nm to 100nm (usually 150nm). Basically, it’s a physical sieving process. It uses pressure as a driving force to separate liquids according to the membrane’s different pore sizes. Under this driving force, the membrane intercepts substances larger than its pore size. Meanwhile, it allows substances smaller than the pore size to pass through, achieving the separation purpose.

There are various materials for ultrafiltration membranes, including PVDF (polyvinylidene fluoride), PES (polyethersulfone), PTFE (polytetrafluoroethylene), and PAN (polyacrylonitrile). These materials have good thermal stability, chemical stability, and resistance to microbial erosion.

PVDF Membranes Electrophoretic paint Hollow Fiber Ultrafiltration Filter UF Membrane membranes come in various structures. These include hollow fiber type (internal and external pressure), tubular type, roll type, and immersion type. Among them, hollow fiber ultrafiltration membranes are widely popular due to their high efficiency, compactness, and ease of maintenance.

Product Paramenters

Performance Characteristics:

Efficient Interception

Firstly, PVDF Membrane exhibit remarkable efficient interception capabilities. They can almost completely intercept suspended solids, colloids, large – molecular substances, bacteria, etc. in water. Additionally, the removal rates of BOD and COD range from 20% to 60%.

Chemical Stability

Secondly, in terms of chemical stability, ultrafiltration membranes have good resistance to various chemical substances. They can withstand the erosion of different chemical agents, which is crucial for their performance in diverse industrial and water – treatment applications.

Resistant to Microbial Erosion

Moreover, when it comes to microbial resistance, ultrafiltration membranes show strong resistance to microbial erosion. As a result, they are not easily contaminated or blocked, ensuring long – term and reliable operation.

PVDF Membrane Long Lifespan

Furthermore, in actual operation, ultrafiltration membranes have an impressive long lifespan. The longest lifespan of ultrafiltration membranes can reach 6 years or even longer, making them a cost – effective choice in the long run.

Low Pressure Drop

Finally, regarding the pressure drop, the operating pressure of ultrafiltration membranes is relatively low. This characteristic helps to reduce operating costs and improve efficiency, making them highly competitive in the market.
