Ultrapure Water Purification Systems
Ultrapure water, as the name suggests, is water purified to the highest standards making it completely free of contaminants. This level of purification is required for advanced analytical techniques, such as HPLC, and is commonly used for semi-conductor manufacturing. To produce ultrapure water a combination of different purification techniques is required to remove different contaminants. This can include ion-exchange resin, synthetic activated carbon, UV photo-oxidation lamps, microfiltration membranes, ultrafiltration membranes. Some systems operate directly from tap water and others from pure water. Due to the high level of purification ultrapure water has low levels of anionic contamination, resulting in ultrapure water having a resistance of up to 18.2 mOhm-cm. When selecting an ultrapure water purification system consider; the available feed water, necessary volumes, and required water quality monitoring.
