You produce demineralised (distilled) water by heating a container of normal water until it is steaming...then you have a hood over top of the water that slopes to one side and is aimed at a different container. The steam will raise up and collect on the hood...the slope will make the condensed droplets slide down to the other container. When the water is turned into steam it leaves behind all the heavy metals/minerals. That is the method of making it yourself..I'm not sure how the large manufacturers of it do it..I'm assuming the same type of idea on a much larger scale.

Distilled water has many uses...such as plating/anodizing baths where foreign minerals in the water would lead to a potential deposit of it in the plating surface.
