15’EDI & CDI: Effect mix of Accepted, Disputed,
Rejected by Western Mainstream(WM)
■ 15’EDI & CDI: Electro De-Ionization(demineralizing thru membrane), & CDI: Capacitive
De-Ionization (porous electrode absorbing ion);
WM Accepted effect: Widely used for Pure water production- sometimes competitively
used for L(Drinking water generation[non desalination]+)(eg combined with water spiral:
BWT SEPTRON+), A2(Salt water desalination)(eg WiseWater Pte, TGH2O,
HydroNovation+), many commercialized techs are competitive in low(<10,000ppm) salinity
only, Advanced low Capex-Opex high salinity application far beyond sea water(35,000ppm)
level(Atlantis technologies+): Radial Deionization with ultralong fast treating water
flow(upto 10m) supercapacitor pair with dielectric spacer in a Concentric Tube.

But actually several mostly uncommercialized techs are much lower power use:
eg1: by tuning the applied voltage frequency into natural frequency of filtering structure
to cause standing wave resonance(cdi-electrosorption.org): This tricky-not always
repeatable(resonance freq & its intensity seems to differ by various elements)- but exact
mechanics is used for many types of over-unity energy devices including water based
H 2 producing devices(see 29'HHO, 63' Other Anomalous Effects[water based energy
generators]).
eg2: No membrane/resin using micropower electrogradiant generator WaterChip
based desalination(Okeanostech): For other range of super low cost desalination being
shelved or actually quietly installed see 10'Ultrasonic, 11'Hydrodynamic Cavitation,
