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
