3M™ Liqui-Flux™ W-Series Ultrafiltration Modules

Advanced membrane technology for economical, reliable water treatment.

Reliable. Economical. Sustainable.

Tough filtration applications like yours – we’re talking TTS, BODs or fats and oils – need more than basic filtration. You need ultrafiltration. Advanced membrane technology from 3M™ Liqui-Flux™ offers effective and economical ultrafiltration treatment to help restore water for reuse, providing you a reliable, economical and sustainable filtration process.

3M™ Liqui-Flux™ offers an economical alternative to conventional treatment. Even when contamination levels fluctuate, 3M™ Liqui-Flux™ W-Series Ultrafiltration Modules demonstrate reliable operation, removing pathogens, turbidity and suspended solids from fresh water, all while pre-treating water for desalination processes, including reverse osmosis (RO.)

More good news? 3M™ Liqui-Flux™ helps you meet your sustainability goals, too. Whether that means cleaning water coming into your operation, recirculating water and chemicals that need to be cleaned, or filtering water before discharging it back to the water system, 3M™ Liqui-Flux™ supports your effort to make your operations more sustainable.

How does it work?

Membranes function as semi-permeable barriers that allow target components to pass through, while retaining others. 3M™ Liqui-Flux™ W-Series Ultrafiltration Modules efficiently separate out microorganisms, suspended solids and other contaminants.

UltraPES hollow fiber membrane is the heart of the 3M™ Liqui-Flux™ Membrane Modules. With well-defined pore structure, and a three-layer morphology with narrow pore size distribution for permeability, it provides excellent permeability and strength.

And, to provide long-term durability, the membrane is stabilized by our Multifiber P.E.T. technology. Its yarn stabilizes the small bundles of hollow fiber membranes, resulting in long life.

Let’s dig deeper into the details of how 3M™ Liqui-Flux™ is made – and learn why it works.

3M™ Capillary Membrane: excellent permeability and strength

Robust asymmetric 3-layer structure

Narrow pore size distribution

Excellent permeability

Reduced fouling potential due to hydrophillic characteristics

High temperature and chemical resistance (pH 1 – 13)
Multifiber P.E.T.™ technology: sophisticated membrane support

Hollow fiber membranes are stabilized by 3M’s multifiber P.E.T. technology, where P.E.T. yarn is twisted round and potted with the hollow fibers.

This provides excellent mechanical support to the membrane and ensures long-term stability.
Controlled hydrodynamics: even flow distribution promotes efficient backwash.The special module design is optimized for favorable hydrodynamic conditions during the backwash procedure.

The introduction of backwash water through a narrowing annular channel ensures a uniform pressure distribution. This leads to excellent physical cleaning performance.

No O-ring seal is required to separate the feed from the filtrate side, reducing the potential for microbiological cross-contamination.
