Can somebody explain to me the differences between ElectroDeionization and just plain D.I.? Does EDI eleminate the need of the giant carbon filter tanks? I am looking to install a DI system in our Mexico facility, so it may be difficult to have a constant cylinder exchange going on like we have here in the states.

You might try looking here:

and then get back to us on what you find out. It looks interesting and expensive. :)

Carbon tanks don't make DI water. AFAIK Unless you mean the resin tanks and are simply calling them carbon tanks.

Both systems I've used had both carbon and an exchange medium each in their own tank.

Our DI system has a carbon cylinder and a mixed bed cylinder.

This is from the Mfgr website:

"The Technical Devices' Nu/Clean Recirculating Water Deionizing System is engineered to remove all organics, chemicals, and heavy metals via particle filters, CARBON, and chelate tanks prior to reaching the ion exchange resins ( cation and anion tanks)."

I have actually figured out my question via some phone calls to different manufacturers of both types. ElectroDeionization completly eliminates the use of any filter medium but should be used in conjunction with a RO system for recirculation.
