Products Description
General Information
VUF- Kristal 600B UF membrane is the direct equivalent, replacement, alternative, retrofit and analogue to replace Hyflux Kristal 600B K-600B (K600B) UF membrane module.
TFERV-70 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.TFERV-70 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 0.03 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 and mechanical strength
Direct and economical module replacement
Applications
Surface water
Well water
Potable water
Municipal sewage
Industrial wastewater
Reclaimed water reuse
RO pre-treatment
Pre-treatment of seawater desalination
