Distilled Water
Distillation is a simple process in which water is heated to its boiling point and allowed to turn into water vapor, or steam. This vapor travels along a conduit to a different location where it cools and condenses back into liquid water. The result is that impurities are left behind in the original container and essentially only pure water is collected in the condensate.

Deionized Water
Deionized water is produced by running water through a bed of a porous polymeric resin, which contains loosely bound hydrogen (H+) and hydroxide (OH-) ions. As water flows over the resin, dissolved charged chemical species in the water -- such as calcium and magnesium -- are bound to the resin, and hydrogen or hydroxide ions are released to take their place. These two ions will then combine to form water. The result is that many of the most common chemical contaminants are removed and replaced with water. The resin is regenerated occasionally to replace the lost hydrogen and hydroxide
