For use with 317 US gallon (1200 liter) emergency tank showers, these non-chemical disinfecting modules provide constant protection against infestations of pathogenic bacteria in water treatment systems. Immersed in water, the complex integral electrolytic activity of the ceramic media produces constant oxidizing, while the noble metal in the form of a fine matrix format produces ionization. The ionization of the noble metal is enhanced by the ceramic media and the combined effect is to act as a powerful disinfectant producing exceptional kill rates against pathogenic bacteria. Additionally, the electrolytic activity of the ceramic media produces a chemical re-action that balances the pH of the water. This results in additional benefits in the form of scale inhibition and corrosion prevention. Optimum operating life of 3 years.
