Microza1 Ultrafiltration Modules
OLT Series
Data Sheet MEOLTEN

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

Features & Benefits■ 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 thehollow fiber. This flow path produces exceptionally cleanwater and eliminates stagnant areas on the permeate side.
■ Large membrane area results in high flow rates per module■ High temperature and pressure modules available

Application

Connections

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 / Reject:
PVDF union sockets for these ports are available forthermal fusion to PVDF piping.
■ Permeate:
Connections are 2 in. or 2 1⁄2 in. 3 piece clamp.
