Ultrapure water systems

Clear Series ultrapure water systems (for IC manufacturing) use a single multifunctional cartridge containing an active carbon stage, a high-performance mixed-bed ion exchanger, and a scavenger stage (containing a mixture of macroporous adsorptive resins). They provide 18.2 M? cm resistivity and 0.2-?m particle removal with a final filter. UV lamps give effective photo-oxidation on organic compounds, resulting in TOC values of <3 ppb, and the ultrafiltration units guarantee pyrogen-free water.
