  • 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 ...
