customized processes as needed
Hollow Fiber Membrane Organic Tubular Membrane
Jiuwu hollow fiber membranes are prepared using Jiuwu organic tubular membrane is categorized into two types: sintered tubular membrane and
non-woven tubular membrane, involving materials such as PVDF, PES, etc. The separation accuracy
high-grade PVDF resin as raw material, based on advanced
of the membrane layer covers 10kD~0.2 μm. The inner diameter of membrane tubes, of which
production processes and hydrophilic modification
non-woven tubular membranes are available in 6mm, 8mm and 10mm, and sintered tubular
technology, with a nominal pore size of 30nm. We have membranes are available in 8mm, 12.7mm and 25.4mm. The size of the modules are 4-inch, 6-inch
developed two modules, Ultrafiltration and MBR, with and 8-inch, in addition, non-standard membrane module with different materials and specifications
can also be customized. The products have been used in processes such as hardness removal of
excellent performance. The product has been widely used
softening, powder cleaning, acidic and alkaline liquid reuse, as well as in applications such as
in fields such as river purification, reclaimed water reuse,
Landfill leachate , reinjection water for oilfield, and plant extraction process.
industrial wastewater pretreatment, municipal wastewater
treatment, drinking water, and seawater desalination.
Advantages of Non-woven Tubular Membrane
Hollow Fiber Membrane—Specification parameters of curtain membrane element · Double-layer non-woven body to withstand higher operating pressure;
· Uniform ultra-thin separation layer, uniform pore size, high separation accuracy;
