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 concern about the timing of changing batches, or planning for the eventual breakthrough of ions in the bed like silica, sodium, or general conductivity.

When combined with RO, EDI can generate ultrapure water continuously for 5 to 8 years, sometimes up to 14 years.

Spikes in species like sodium (Na+) and silica (SiO2) are particularly worrisome for power plants, who expect a guaranteed maximum level. Fear of spikes lead to premature chemical regeneration of the mixed bed polishers.
