ZW700B 250

Summary

Product identification

• Model: ZW700B-250/UF10/7B/S/0.9/0.6
• Description: ZeeWeed 700B-250 Ultrafiltration (UF) module featuring SevenBore fiber technology with an inside-out flow orientation.
• Membrane Material: Polyether sulfone (PES)
• Membrane Type: SevenBore
• General Properties:
  • UF membrane for optimal removal of particulates, bacteria, and viruses.
  • PES membrane fibers with 7 bores provide high mechanical strength (>10x that of single fibers) and chemical resistance.
  • Inside-Out filtration eliminates air scouring step and additional related equipment.
