EDI Ultra pure water system ndi mtundu waukadaulo wopangira madzi oyera kwambiri omwe amaphatikiza ukadaulo wa ion, ukadaulo wa ion membrane exchange and electron migration technology.Ukadaulo wa electrodialysis umaphatikizidwa mochenjera ndi ukadaulo wosinthira ion, ndipo ma ion omwe amaperekedwa m'madzi amasunthidwa ndi kuthamanga kwambiri kumapeto kwa ma elekitirodi, ndipo utomoni wa ion exchange resin ndi nembanemba yosankha utomoni imagwiritsidwa ntchito kufulumizitsa kuchotsedwa kwa kayendedwe ka ion. monga kukwaniritsa cholinga chochotsa ma ion abwino ndi oipa m'madzi.Ndi ukadaulo wapamwamba, zida zamadzi zoyera za EDI zokhala ndi ntchito yosavuta komanso mawonekedwe abwino kwambiri a chilengedwe, ndiye kusintha kobiriwira kwaukadaulo wa zida zamadzi oyera.
