As someone who scraped by chemistry in college, is it fair then to say that the "effects on pH" section should simply say that no matter what the pH of the water going in, after electrodeionization the pH will be 7? Because currently the pH section is useless as it simply defines pH (done elsewhere, and that information should be known by anyone who can understand the rest of this article) and does not say anything at all about the effects of this process on the pH of the solution Dreamingkat (talk) 19:31, 17 February 2009 (UTC)[reply]

Michael, I deleted the other two topics because pH and ORP have no relevance to the topic of Electrodeionization. As a chemical engineer and water professional in the industry for 15 years, I just want to make sure the information is correct. pH is a measure of H+ ions and the product of electrodeionization is deionized water, i.e. zero ions. Therefore pH of deionized water is 7 which is neutral. ORP is oxidative reduction potential, also a measure of ions or consituents in water than are "oxidative" or some would say corrosive. Again DI water does not have this. Let me know if you do not agree with this or delete these two topics. —Preceding unsigned comment added by Yenner (talk • contribs) 18:47, 18 March 2008 (UTC)[reply]

Yenner -I appreciate your adding to this page, greatly and you added many of the stuff I intended on getting around to add. However you deleted information on how the process effect the properties such as Ph and ORP. Of which I would appreciate if you would put back in. Also you deleted the basic electrochemical reaction that takes place between the Hydrogen and Oxygen Ions.

The article now has morphed to be a discussion of Continuos Electrodeionization versus the fundamental physics and chemistry of Electrodionization. Which is all good but we need to put the fundamentals in too.

Thanks for your help.

Feed Water tolerance

Standard electrodeionization systems are limited to feed water with less than 0.5 to 1.0 ppm as CaCO3 and 10-40 microsiemens/cm (10-25 ppm TEA). High hardness modules are available for up to 2 ppm hardness and thin cell CDIT can handle up to 4 ppm hardness and 100 microsiemens/cm.
