Equivalent, replacement, alternative, analog, retrofit, analogue, derivative, substitution: Membrana Liqui-Flux Membrane Module UF-PES Series Type W20

General Information

TFLQ91 is manufactured as the direct equivalent, replacement, alternative, analog, retrofit, analogue, derivative and substitution to replace Membrana Liqui-Flux W10 UF membrane module.

TFLQ91 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 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
