Products Description
General Information
VUF- K-600ER0820 UF membrane is an equivalent, replacement, alternative, analog, retrofit and analogue to replace Hyflux KRISTAL K-600ER0820 (K600ER0820) UF membrane module.
VUF- K-600ER0820 UF membrane 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.VUF- K-600ER0820 UF membrane 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
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.
