TaFlux HFU Series

General Information

TaFlux HFU series ultrafiltration (UF) membrane module 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

TaFlux HFU Series PVDF UF Membrane Module

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 desalinationn
