Microza UF Modules, OLT Series

The Microza1OLT ultrafiltration (UF) modules feature hollow fiber membranes having a uniformly smooth, tight skin on both the inside and outside of the fiber.
  • Low metal extractables by pre elution using new hot water rinsing process
  • Up to 12 months on shelf life ex works due to hot water sanitization2
  • Shipped water wet
  • Designed specifically for ultra high purity water
  • Polysulfone membranes and housings
  • 6,000 and 10,000 molecular weight cut off ratings
  • External feed:
    • Feed water flows from the outside to the inside of the hollow fiber. This flow path produces exceptionally clean water and eliminates stagnant areas on the permeate side.
  • Large membrane area results in high flow rates per module
  • High temperature and pressure modules available
