The Electrodeionization (EDI) is one kind of pure water manufcturing technology of the union of the ionic exchange technology, the ion selectivity penetration membrane, the ion electicity gration, the water polarization and ionization. The use of masculine and feminine ionic exchange (seepage) the membrane, the ion exchange resin and the pale and concentration water separetion room to compose working space, and assembles according to the need as soon as fixes production quotas the water ability the mold to pile, realizes high quality under the direct current actuation, highly effective purifies the water. The EDI desalinization rate may reach as high as above 99.9%, the water leakage electronic resistivity may reach as high as 18M Omega/ cm.
Work originally to be supposed
Principle like chart 1: In chart obviously:
The original water divides two groups comes on the line unit module. The ion (Na or CI and so on) in pale water room are pale water room carries on the ionic exchange and separately passed through cloudyly, the positive ion exchange membrane under the direct-current field function enters the concentration water room, but concentrates the room the current of water to carry Na or outside the CI plasma discharger, simultaneously the resin - resin, the resin - membrane contact surface hydrone dissociates under the electric current function produces H and OH carries on the regeneration to the expiration ion exchange resin. The above process along with the electric current conduction (ionic migration), in working space interior continual again and again carrying on, this had achieved requests effect, when enters the water water quality and the operating condition (electric current, voltage and so on) achieved when produces the water water quality balance stable best value, then long-term continuous working.

The EDI merit continuous running, the water leakage water quality stable
Reduction floor space reliably
Does not need with the acid and soda, medicament regeneration production
Safety to be possible to realize the modular assembly
Service to be simple, not to need the engine off overhaul movement Cost low
Application scope:
widely to apply to profession and so on thermal power plant, electron, medicine, chemical industry, food, drink.
