Beco Membran PF Plus

Summary

Product identification

The BECO MEMBRAN PFplus is a membrane filter cartridge specifically developed for the beverage industry as a final sterile end filter prior to bottling. It is designed for use after pre-filtration (e.g., using BECO depth filter sheets or pre-filter cartridges).

• Pore sizes:
  • 0.22 µm (KVBL range for bacteria retention)
  • 0.45 µm (KVBB range for bacteria retention)
  • 0.65 µm (KVBY range for yeast retention)
  • 1.0 µm (KVBA range for yeast retention)
• Materials:
  • Pleated, hydrophilic polyvinylidenefluoride (PVDF) membranes
  • Inside and outside support corpus and end caps made of polypropylene
  • Silicone O-rings

Operating limits

• Maximum differential pressure (in direction of flow):
  • 5.50 bar at 125 °C
  • 1.70 bar at 180 °C
  • 0.35 bar at 121 °C
• Maximum differential pressure (against flow direction): 3.5 bar at 25 °C (intermittent)
• Maximum operating temperature: 80 °C
• Resistance to hot water rinsing: Up to 95 °C
• Sterilization:
  • Max temperature of 95 °C (hot water)
  • Saturated steam at a max temperature of 109 °C for a period of 20 minutes (after steam has emerged from all openings and valves)
• Chemical resistance: Wide resistance (< pH 12) to common cleaning agents

Feed water

• For rinsing and sterilization, the water should be decalcified and filtered (1 µm).

Product water

The filter cartridges guarantee reliable filtration of yeast and bacteria.
