ULTRA-PURE WATER FOR ULTRA-SENSITIVE APPLICATIONS

Ultra-pure water is needed above all in the electronic and pharmaceutical industries. Demands made on the ion exchange resins used in these sectors are extremely high.

Because of the stringent specifications on water quality in terms of TOC emissions and residual ion contents, the ion exchange resins used for such applications have to be specially purified and treated.

The pharmaceutical industry needs ultra-pure water, for example for sterile applications and processes under cGMP conditions. In certain constellations, the Lewatit® specialists can compile data for pharmaceutical customers needed for certification of the water treatment - for licensing procedures or official audits, for example.

The Lewatit® range also includes a line of ion exchange resins developed specifically for the production of ultra-pure water for the highly sensitive production of semi-conductors, processors and electronic components. Residual salts or organic components remaining in the water can cause enormous damage, and can well be the reason for short circuits between the conductive tracks on a chip. The greater the density of the conductive tracks, the higher the specifications regarding the quality of the water.
