General Information
TaFlux HFU series ultrafiltration (UF) membrane module TFHFU-2020A is a pressurized module, which is designed and manufactured for the filtration of surface water, potable water, seawater, industrial wastewater and municipal sewage. These UF modules are made of new generation PVDF hollow fiber membrane with high fouling resistance and hydrophilicity.TaFlux HFU series UF 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 0.01 μm
- Typical filtrate quality SDI ≤ 2.5, turbidity ≤ 0.1 NTU
Advantages
- High tolerance for feed water and high-quality filtrate
- Smaller footprint design with CAPEX reduction
- Less energy needed by high flux
- Longer service life by high fouling resistance and mechanical strength
- Direct and economical module replacement
Applications
- Surface water
- Well water
- Potable water
- Industrial process water
- Reclaimed water reuse
- Pre-treatment of sea water desalination
