TaFlux ERV Series
General Information
TaFlux ERV series UF membrane module is a pressurized ultrafiltration membrane module, 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.TaFlux ERV series UF membrane module is 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 0.03 μm
- Typical filtrate quality SDI ≤ 2.5, turbidity ≤ 0.1 NTU
Advantages
- High tolerance for feed water
- High quality raw material
-
Less energy needed by high flux
- Longer service life by high fouling resistance and mechanical strength
- Economical equivalent UF membrane module for direct replacement
Applications
- Surface water
-
Well water
- Potable water
- Industrial wastewater
- Reclaimed water reuse
- RO pre-treatment
- Pre-treatment of seawater desalination
