Application Scenarios

The TARGAII10048-35-PEC UF membrane is particularly well-suited for electronic grade ultrapure water systems, which are essential in modern high-tech industries:

• Semiconductor Fabrication Plants: To safeguard wafer processing, photoresist application, and etching procedures by removing colloids, viruses, and submicron particles from pre-RO or polishing loop water streams.

• Flat Panel Display (FPD) Manufacturing: To ensure defect-free production of LCD and OLED screens by using water free of ionic and organic impurities.

• Photovoltaic Cell Production: To support crystal washing and surface cleaning operations where ultrapure water quality directly influences cell efficiency and lifetime.

• Precision Optics and Microelectronics: Ideal for supporting the final rinse or chemical blending stages where impurity levels must be kept below parts-per-trillion (ppt) levels.

LEFILTER’s UF solution is a pivotal pre-treatment or polishing stage to reverse osmosis (RO) and mixed-bed ion exchange systems in UPW processes, reducing fouling risk and extending downstream component lifespan.

FAQ

Q1: How does this membrane compare to the original Koch TARGA II series?
