General Information
Hollow fiber UF membrane TFZW55 is a pressurized membrane of hollow fibers, which is designed and manufactured for the filtration of surface water, potable water, seawater and industrial wastewater. These UF modules are made of new generation PVDF hollow fiber membrane with high fouling resistance and hydrophilicity.TFZW55 hollow fiber UF membranes are applied in new systems, as well as directly connected to existing UF systems as replacements, providing high-quality filtrate by removing suspended solids, colloids, pyrogens, bacteria, viruses and other impurities to protect downstream processes.
Features
- Outside-to-inside flow direction
- New generation PVDF hollow fiber
- Uniform pore size of 0.02 μm
- Typical filtrate quality SDI ≤ 2.5, turbidity ≤ 0.1 NTU
Advantages
- High tolerance for feed water
- High-quality filtrate
- Less energy needed with high flux
- Longer service life by high fouling resistance and mechanical strength
- Economical equivalent module for direct replacement
Applications
- Surface water
- Potable water
- Industrial wastewater
- Reclaimed water reuse
- Pre-treatment of seawater desalination
