Electrodeionization (EDI) using Voltage Control
In electrodeionization, DC voltage is the force for driving ions out of the stream to be purified. Current is a result of the movement of ions. Both as a matter of physics and as a practical matter, SnowPure recommends using “Voltage ...
-
Electrodeionization is a Continuous Process
Unlike mixed bed DI, electrodeionization (EDI) is continuous. Because electrodeionization is continuous there are no spikes in quality as when mixed beds are changed for batch regeneration. An additional benefit for EDI users is that there is no ...
