TaFlux ETV Series
General Information
TaFlux ETV series uf modules are pressurized UF modules, which are 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.TaFlux ETV series 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
- Nominal pore size of 0.025 μm
- Typical filtrate quality SDI ≤ 2.5, turbidity ≤ 0.1 NTU
Advantages
- High quality raw material
- High thermal and chemical solvent resistance
- High chemical tolerance for cleaning
- Optimized design, high resistance to fouling
- Economical equivalent UF modules for direct replacement
Applications
- Surface water
- Potable water
- Pre-treatment of seawater desalination
-
Pre-treatment of industrial water
- Industrial wastewater
