Dionized Water - Deionization is a completely different process to Reverse Osmosis and requires different equipment. It removes salts from water and relies on their ionic nature for their removal. It leaves behind any species that are not ionic in nature, including organic molecules and even bacteria.

This is a bit misleading. Although referred to as "deionized" it is actually ion exchange, one ion takes the place of another.

It leaves behind any species that are not ionic in nature, including organic molecules and even bacteria.

This is true, except that you don't run domestic water straight into the resin tanks and out to the loop. The feed water is Reverse Osmosis so most impurities are already removed. It also goes through an ultraviolet sterilizer to kill bacteria. Lastly it is filtered at the sub-micron level to remove the destroyed bacteria and any endotoxin that may have been released into the water stream.
