An integrated prefilter protects the RO membrane from impurities in the feed water.

The concentrate, which is normally discharged directly into the drain, is recirculated to minimise the waste water.

The ion exchange beds in the EDI cell are regenerated continuously so that they do not exhaust in the same way as common ion exchangers. 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 will increase the lifetime of the final polishing cartridge significantly and also deliver more consistent purity than single-bed ion-exchange systems that may release weakly bound ions as the media exhausts. The EDI module also reduce the release of organic impurities. This helps to lower your operating costs.

The permeate is circulated depending on the conductivity to extend the lifetime of the EDI module and subsequent periphery and to guarantee a constant water quality.
