EDI (Nruam Electrodialysis) modules yog cov dej ntshiab huv uas ua ke nrog electrodialysis thiab ion exchange technologies. Lawv cov thev naus laus zis thev naus laus zis siv hloov pauv cation thiab anion pauv daim nyias nyias los tsim cov desalination thiab concentration chambers. Tsav los ntawm DC hluav taws xob teb, qhov no tso cai rau kev txav mus los thiab tshem tawm cov ions ntawm dej. Ib txhij, cov hydrogen thiab hydroxide ions tsim los ntawm dej dissociation pab kom tsis tu ncua electrochemical regeneration ntawm resin, tshem tawm qhov xav tau rau cov tshuaj acid thiab alkali tshuaj reagents.
Cov thev naus laus zis no muab cov txiaj ntsig zoo xws li xoom paug paug tawm, ua haujlwm tsis siv neeg, thiab ruaj khov thiab tswj tau dej zoo. Nws tuaj yeem tsim cov dej ntshiab huv nrog kev tiv thaiv ntawm 15-18 MΩ·cm thiab tau siv dav hauv kev lag luam xws li lub zog, hluav taws xob, kev kho mob, thiab kev ua tshuaj lom neeg.
