The ion exchange beds in the EDI systems are regenerated continuously so that they do not exhaust in the same way as ion exchange beds that are operated in batch mode. As the impurities are removed via the concentrates, they do not build-up and exhaust the resin. An EDI unit may operate for many years before a replacement is required. Typically product water resistivity of >15 MΩ.cm is consistently achieved using this process. This technology can be used as an alternative to single-use purification cartridges. As well as the practical advantages and reduction in down-time of avoiding changing cartridges, EDI can also deliver more consistent purity than single-bed ion-exchange systems that may release weakly bound ions as the media exhausts. The smaller volumes of resin in an EDI module (compared to an ion-exchange bed) also reduce the release of organic impurities.
