This UF membrane (ultrafiltration membrane) is designed for ultrapure water production processes essential for advanced LSI manufacturing.
Microza® Water Treatment Process OLT Series

High-Quality UF Membrane Optimized for Ultrapure Water Production

The Microza® OLT Series has a proven track record in advanced LSI factories, providing high-precision water quality and reliability. It also meets various process requirements with a range of pressure and heat resistance capabilities.

Details of Water Treatment Process OLT Series

Features of Water Treatment Process OLT Series

Double-skin structure that collects filtered water from both ends of the module to reduce pressure loss and achieves high water quality with dense membrane structure on both inner and outer surfaces (Learn More Here).

Long-term storage under specified conditions* is possible by filling with heat-sterilized pure water. *In a cool, dark place away from direct sunlight.

High cleanliness enables rapid stabilization of particles, TOC, and specific resistance.

A wide lineup is available, including a pressure-resistant type rated at 1,200 kPa (40°C) and a heat- and pressure-resistant type rated at 800 kPa (80°C).

Technical Information

OLT-6036 Series Fine Particle Rinse-Up Data

This data compares rinse time and changes in fine particle count for the OLT-6036 Series, showing a decrease over time in particles of 0.05 µm and 0.10 µm or larger. Continued rinsing results in both particle counts stabilizing at low levels, confirming the achievement of clean water quality.

OLT-6036 Series TOC Data

This data shows changes in rinse time and TOC (total organic carbon) concentration for the OLT-6036 Series. TOC is initially high but decreases rapidly with continued rinsing, eventually stabilizing at a low level below 1 ppb. The OLT-6036 Series quickly reduces initial TOC and maintains low levels over the long term.
