Membrane Filters: Spiral-Wound Ultrafiltration Elements

Synder currently offers 22 different Ultrafiltration membranes that are all available for purchase as flat sheet or spiral would element configurations. Polymer types include PES (polyethersulfone), PVDF (polyvinylidenedifluoride), and PAN (polyacrylonitrile), and molecular weight cut-offs start at 1,000 Daltons and go up to 500,000 Daltons.

1.Spiral_Element_Construction 623x351Ultrafiltration membranes are available in many different configurations, including hollow fiber, tubular, flat sheet, and spiral-wound. When total suspended solids are mostly removed with pre-filtration, spiral-wound ultrafiltration elements are preferred choices because they provide a balanced combination of active membrane area density, physical durability, membrane life, and unit cost.

Sanitary Spiral-Wound Elements

Industrial Spiral-Wound Elements

Synder Filtration currently offers twenty-two different molecular weight cut-offs and sizes for spiral wound ultrafiltration elements, available in both sanitary and industrial grades. With molecular weight cut-offs ranging from 1,000 – 500,000Da and membranes available in both PES and PVDF polymer materials, Synder’s ultrafiltration membranes offer great flexibility and pore selectivity. More information can be found in our sanitary and industrial catalogs.

For element sizes not listed, please call or email Synder Filtration for details. We can design an element to fit your exact needs – just specify the element outer diameter (OD) or vessel/ housing inner diameter (ID), element inner diameter (ID), and length. Elements are available with or without a controlled bypass tail. Trials should be conducted to determine optimal application conditions.
