W20-08N-RAS111 Equivalent

Equivalent, replacement, alternative, analog, retrofit, analogue, derivative, substitution: 3M Liqui-Flux Membrane Module UF-PES Series Type W20-08N-RAS111, W2008NRAS111

General Information

TFLQ91-RAS666 is manufactured as the direct equivalent, replacement, alternative, analog, retrofit, analogue, derivative and substitution to replace 3M Liqui-Flux W20-08N-RAS111 (W2008NRAS111) UF membrane module.

TFLQ91-RAS666 ultrafiltration (UF) membrane modules are pressurized modules, which are designed and manufactured for the filtration of surface water, potable water and process water etc. These UF modules are made of new generation PES hollow fiber membrane with high fouling resistance and hydrophilicity.

TFLQ91-RAS666 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

  • Inside-to-outside flow direction
  • New generation PES hollow fiber
  • Nominal 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 by high flux
  • Longer service life by high fouling resistance
  • Direct and economical module replacement

Applications

  • Surface water
  • Potable water
  • Industrial process water
  • Pre-treatment of sea water desalination
