Ultrapure Water Filtration for Display Manufacturing
Achieving and maintaining ultrapure water (UPW) is extremely important in light of its widespread presence throughout the production of display devices.
The technology of the industry has advanced so rapidly over the past few years that it has redefined cleanliness requirements, specifically with regard to the need for quantitatively removing colloidal silica, particles, total organic carbon (TOC), bacteria, pyrogens (bacterial fragments) and metal ions.
A well-designed UPW system with strategically placed filters, will ensure achievement of this goal, since the type of filter selected in each of the key areas will make a measurable difference in ultimate quality.
To meet the demands of a high-purity deionized (DI) water system, filters must:
Products for Ultrapure Water Filtration in Display Manufacturing
Filter CartridgesAsymmetric P-Nylon Filter (Ultrapure Water Filtration)
This filter's tapered pore design, with an opened upstream structure and a fine downstream region, allows for filtration removal ratings down to 20 nm with very low differential pressures.
Nexis® A Series Filter Cartridges
This filter cartridge resists contaminant unloading even at high differential pressures.
Nexis® T Series Filter Cartridges
This filter cartridge has a continuous gradient pore structure media thatprovides both prefiltration and final filtration.
Poly-Fine® XLD Series Filter Cartridge
This filter cartridge features an innovative merger of depth and pleated technologies that deliver high flow rates with low pressure drops.
Posidyne® UP Filter
The Posidyne UP filter is well suited for ultrapure water application for today's advanced semiconductor manufacturers.
Profile® II Filters
Profile II filters are proven to remove 99.98% of the contaminants at their micron rating. They are ideally suited for pre-RO, resin trap and cooling water applications.
Profile® UP Filter
