PHT Sanitary Ultrafiltration Spiral-Wound Element:
LV (PES 200kDa)
Synder Filtration’s PHT Series of Ultrafiltration Elements offer exceptional physical and chemical durability, in the same wide range of MWCO’s as our standard UF elements. Contact us today to learn more about our complete line of membrane products and services.
LV is a newly-developed PES-based ultrafiltration membrane, with a molecular weight cut-off between that of LY and LX. This membrane was developed to further expand Synder’s ultrafiltration line of membranes and offer more choices for molecular weight cut-off to meet the demands of specialty process applications. Along with the other PES-based membranes, LV offers good pH and temperature resistance and is also available in a PHT version which is able to withstand higher pH and temperature limits. LV is also commonly used for corn wet milling processes to reduce operational and discharge costs.
PHT SERIES BENEFITS
- Conforms to 3-A, FDA, and USDA sanitary standards
- Elimination of chlorine during CIP with hot sanitation
- High resistance to pH, temperature, & fouling
- Customizable dimensions for unique housings
COMMON APPLICATIONS
- Corn wet milling

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.
