General Information
TaFlux ZW 55 series TFZW55C ultrafiltration (UF) membrane module is a pressurized module, which is designed and manufactured for the filtration of surface water, potable water, seawater and industrial reclaimed water reuse. These UF modules are made of new generation PVDF hollow fiber membrane with high fouling resistance and hydrophilicity.TaFlux ZW 55 seriesTFZW55C UF modules 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 process water
- Reclaimed water reuse
- Pre-treatment of seawater desalination
