General Information

TFETI-55 is an equivalent, replacement, alternative, analog, retrofit and analogue to replace Hyflux K600ETI - 55 (KRISTAL 600ETI - 55) UF membrane module.
TFETI-55 ultrafiltration (UF) membrane module is a pressurized module, which is designed and manufactured for the filtration of process, potable water and wastewater. Major applications are the filtration of surface water, potable water, industrial wastewater and municipal sewage. These UF modules are made of naturally hydrophilic PES hollow fiber ultra-filtration membrane with excellent performance.
TFETI-55 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.


  • A nominal molecular weight cut off of 120K Dalton
  • Microporous symmetric structure
  • Naturally hydrophilic membrane composed of a blend of polyethersulfone and polyvinylpyrrolidone
  • High performance and very good anti-fouling characteristic
  • Typical filtrate quality SDI < 2.5, turbidity < 0.1 NTU
  • Membrane filtration provides 99.9999% (LOG 6) reduction of bacteria (Pseudomonas diminuta) and 99.99% (LOG 4) reduction of virus (MS2 colifages) by mechanical means.


  • High quality raw material
  • High thermal and chemical solvent resistance
  • High chemical tolerance for cleaning
  • Optimized design, high resistance to fouling
  • Direct and economical module replacement


  • Surface water
  • Potable water
  • Pre-treatment of sea water desalination
  • Pre-treatment of industrial water
  • Industrial wastewater
  • Municipal sewage
