Application
*When fed with low
total dissolved solids
(TDS) feed (e.g., feed purified by RO), the product can reach very high purity levels (e.g.,
18 megohms/cm
).

The ion exchange resins act to retain the ions, allowing these to be transported across the ion exchange membranes. The main applications of EDI technology, such as that supplied by Ionpure, E-cell and SnowPure, PND EDI, are in electronics, pharmaceuticals and power generation.
One important aspect in the water treatment application is that some types of EDI needs to have feed water that is free from
CO2
, as well as other dissolved gasses, since these put unnecessary strain on the EDI unit and will reduce performance.
RO System + EDI System output pure water can widely
apply to disinfectant acid water spray in the anti-corona-virus.
