Pleated Polyethersulfone (PES) Membrane for Critical Filtration in Wine and Beer

 ZTEC WB cartridge filters utilize a special polyethersulfone membrane to provide consistent removal of spoilage organisms and inorganic particulate. The product offers excellent retention efficiency and extended on-stream life making it an ideal filter for the clarification of beer and wine.

The PES membrane, available with either 0.65 or 0.45 μm pore sizes, is designed to meet and surpass the filtration criteria necessary to maintain product quality and characteristics. Produced in an ISO Class 7 cleanroom, the cartridges are integrity tested during production to assure performance and consistency.

Filter Features– Benefits

  • Manufactured in an ISO Class 7 Cleanroom Environment
  • 100% flushed with 18MΩ water and integrity tested
    Low adsorption of protein, color and flavor components
  • All materials are FDA listed for food and beverage contact
  • Repeatably Steamable/Sanitizable
    High log reduction values for spoilage organisms
  • High retention (LVR>7) of yeast and other spoilage organisms
  • Pore size, lot and serial number are stamped on each filter element for identification and traceability
