German PES membrane module for UF introduced
A polyethersulfone (PES) ultrafiltration (UF) membrane module, the Liqui-Flux® W10 has been introduced by Membrana GmbH, based in Wuppertal, Germany.
The introduction of VCCTM into Membrana's Liqui-Flux® W10 UF 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.
The flexibility of being able to choose a configuration that meets specific onsite 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 Liqui-Flux® W10 Ultrafiltration Module uses the proven, 3-layer UltraPESTM capillary membrane for superior permeability and mechanical strength. Using proprietary Multifiber PET® Technology, hollow fibers are entwined with a spacer yarn that provides additional membrane stability.
These multifiber strands are encased in 9 rigid polypropylene bundles positioned in an advantageous hydrodynamic arrangement inside the PVC vessel. This arrangement forms a narrowing annular gap, ensuring even pressure distribution during backwash.
