Industrial PVDF hollow fiber Ultrafiltration Membrane Cartridge – Outside-In Pressure UF Element

  • Made of PVDF material, offering excellent chemical resistance and superior oxidation stability.
  • High filtration precision with a nominal pore size of 0.03 μm and uniform pore distribution.
  • High mechanical strength and flexibility — membrane fibers feature an elongation rate exceeding 100%.
  • Low pressure, high flux — achieves designed flow rates even under very low transmembrane pressure.
  • Excellent chemical stability — membrane performance remains unchanged after 50 cycles of acid and alkali cleaning.
  • Strong anti-fouling capability — cleaning intervals extended by 30%, with effective flux recovery after cleaning.
  • Outside-in flow design — provides higher contamination tolerance and wider adaptability to feed water quality.
  • Standardized connection fittings — significantly improve ease of installation and module compatibility.

PVDF hollow fiber ultrafiltration membrane cartridge features excellent resistance to oxidation, aging, and chemicals, along with outstanding anti-fouling performance. The PVDF fibers undergo a special hydrophilic modification process that greatly enhances their surface hydrophilicity, resulting in higher water permeability, longer service life, and improved fouling resistance. After years of application and development, these membranes have been widely used in industrial wastewater treatment, municipal sewage treatment, water reclamation, drinking water purification, industrial process water, and pretreatment for pure and ultrapure water systems.

FAQ

If our existing UF membrane element is from a big brand, can you provide a 100% compatible replacement?

Yes. Just tell us the brand and model number. For many major brands, we can supply a 100% compatible UF membrane element without any modification to the pipe connections.

  • We have tubular UF membranes, submerged MBR membranes, spiral UF membranes, and ceramic UF membranes.

Yes, we supply both UF membrane elements and UF systems. Our customer in Mexico said that importing a UF system from us would not cost more than assembling it locally.

Yes, we provide a free goods inspection service. If your supplier is within 200 km of our company (Chengdu), even the transportation cost will be covered by us. If the distance is more than 200 km, only the transportation and hotel costs will be borne by you.

Yes, for each item, there will be a minimum order quantity, and then we can produce an OEM order for you.

Yes, whether they are water- or wastewater-related products, we can source them for you. We have been working in the water and wastewater fields for more than 10 years.
