EDI‌ - ‌High‌ ‌Purity‌ ‌Water‌ ‌Production‌ ‌Depends‌ ‌on‌ ‌It‌

In the 1950s', electrodeionization (EDI) technology was invented in an attempt to minimize or eliminate polarization phenomenon concentrations that were present in electrodialysis systems. Decades later, the technology was applied to polish reverse osmosis product water and generate chemical free high purity water. Today, many OEMs use EDI. Electrodeionization technology uses ion-exchange resin ...

How Can Using an Electrodeionization System Help You Save Money?

Electrodeionization (EDI) is an electrically driven water treatment machine that may be used in conjunction with (or in place of) your facility's existing water solution. Electrodeionization technology removes water impurities by combining electricity with ion exchange resin to deionize water, thus removing materials such as salts and other contaminants. Below are some reasons why you may ...

History of Electrodeionization

Electrodeionization (EDI) history extends back to the mid-1970’s in the USA. Possibly back to Argonne National Labs in the 1950’s as a scientific novelty. However, the first working EDI modules were made by Harry O’Hare in 1977 and 1978, and were tested by the Southern Research Institute (SRI). The concept was “filled-cell ED”, an attempt to use the ED concept to ...
