Corrosion of stainless steel pipes in a hydrotherapy pool by a silver-copper disinfection system.
The silver-copper disinfection system has been shown to be effective for water purification. It emits silver ions that combine with bacteria, causing their death. While disinfecting the water, these silver ions exhibit adverse effects on the stainless steel pipes in hydrotherapy pools. In an oxidation-reduction reaction the silver ions are converted into solid silver that is deposited on stainless steel, causing a corrosion reaction. The corroded steel has a black deposit that readily adheres to the burned patient's skin.
