Membrana GmbH, a leading membrane and membrane device manufacturer, is pleased to announce the introduction of the L3M iqui-Flux W10 Ultrafiltration Module that utilizes the proven UltraPES™ polyethersulfone membrane for inside-out operation. With 75m2 of membrane area, this new module design is both functional and durable and also features the innovative Variable Connect Concept - VCC™.

The introduction of the VCC™ into the 3M Liqui-Flux W10 Ultrafiltration Module allows system integrators to select from a variety of connection options to accommodate for the many space limitations and different water qualities faced in the field. Configurations include:

  • The Standard Setup which features a radial feed inlet port and axial concentrate port. This configuration is ideal for treating a broad range of feedwater qualities.
  • The Compact Setup uses two radial ports and is only 1.5m in height. This configuration is well-suited for installation in areas with height limitations.
  • The Optimized Footprint Setup utilizes an axial feed port that reduces the space between modules, thereby reducing the overall system footprint. By using this configuration a 4.75 m2 module skid with 2100 m2 membrane area can be built.

The flexibility of being able to choose a configuration that meets specific on-site needs allows system engineers to build more cost-effective systems with a smaller footprint.

All configurations can operate in dead-end mode. The Standard Setup and Compact Setup can operate in cross-flow mode. Additionally, a second filtrate port can be added and end caps are designed with flat, rectangular surfaces to allow for easy mounting and connecting to other modules. Ports are available in 73 mm, 75 mm and 76 mm sizes to meet regional dimension requirements.

The 3M Liqui-Flux W10 Ultrafiltration Module uses the proven, 3-layer UltraPES™ capillary membrane for superior permeability and mechanical strength. Using proprietary Multifiber P.E.T.® Technology, hollow fibers are entwined with a spacer yarn that provides additional membrane stability. These multifiber strands are encased in 9 rigid polypropylene bundles that are positioned in an advantageous hydrodynamic arrangement inside the PVC vessel. This arrangement forms a narrowing annular gap, ensuring even pressure distribution during backwash.

Membrana GmbH has been a technological leader in membrane development and manufacturing for over 40 years. Its experience spans over 20 years for module development and manufacturing. Membrana’s two primary business focuses are healthcare and industrial & specialty filtration. In addition to the 3M Liqui-Flux brand of filtration products Membrana GmbH also manufactures many membranes that are used in a variety of filtration applications as well as 3M Liqui-Cel Membrane Contactors which are used around the world for degassing and gas absorption in many industries.
