Investigation of an ultrasound device used for CaCO3 de-scaling of drinking water.

A commercially available ultrasound device used for CaCO3 descaling of drinking water is investigated for potential effects on CaCO3 crystal formation and on physical, chemical and spectroscopic differences on water. We have tested FT-IR, Surface enhanced Raman spectroscopy, surface tension, viscosity, pH, Oxidative/reductive potential, particle charge (zeta) potential, Scanning electron microscopy of a water drop dry residue and X-ray crystallography (XRD) of dry residue content. The drinking water samples were exposed to 1 hour and 2 months continuous ultrasound, and compared to non exposed drinking water. A weak effect is seen after 1 hour ultrasound treatment of water when looking at morphology of drop dry residue and on zeta potential.
