Industrial Microfiltration Spiral-Wound Element
V0.2 (PVDF 0.2 µm)
Synder Filtration’s Microfiltration Elements offer an optimal combination of both flux and rejection in a comprehensive range of MWCO’s. Contact us today to learn more about our complete line of membrane products and services.
Synder’s V0.2 microfiltration membrane has the largest molecular weight cut-off of all available Synder membranes. Given the large pore size, this membrane is commonly used for the separation of large macromolecules and can be used in addition to pretreatment options for wastewater applications. Other common uses for this membrane include microbial removal, enzyme clarification, gluten processing in corn wet milling, wine clarification, and plant extract clarification.
INDUSTRIAL SERIES BENEFITS
- Good resistance to pH and temperature
- High resistance to fouling
- Customizable dimensions for unique housings
COMMON APPLICATIONS
- Microbial removal
- Enzyme clarification

TECHNICAL NOTES
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 also available with or without a controlled bypass tail. Additional feed spacers are also available. Trials should be conducted to determine optimal application conditions.
