Microza UF Modules, OLT Series

The Microza¹ OLT ultrafiltration (UF) modules feature hollow fiber membranes having a uniformly smooth, tight skin on both the inside and outside of the fiber.

• 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

The OLT modules are recommended for high purity water systems where the TOC is less than 20 ppb and the particle counts in the feed are as shown in the table below.

Feed Conditions

Particle Size	Maximum no. of particles/ml
> 0.1 μm	100
> 0.2 μm	20

Connections

Feed/Reject: PVDF union sockets for these ports are available for thermal fusion to PVDF piping.
Permeate: Connections are 2 in. or 2.5 in. Tri-Clamp¹
