Abstract
The "hardness" of water flowing through a pipe, and attributable to ions dissolved in the water, is reduced by producing molecular agitation in the water to transform the ions into much larger crystals, followed by filtration using a conventional filter having a mesh size much larger than the size of the ions, but smaller than the size of the crystals.
