Abstract

Electrolytically generated copper:silver ions were evaluated as an alternative disinfectant to high levels of chlorination in swimming pools. Pure cultures of Escherichia coli and Streptococcus faecalis were individually tested by inoculating autoclaved well water (containing 460 ug/L copper and 75 ug/L silver) with and without 0.20 mg/L free chlorine. Copper:silver ions in combination with free chlorine reduced bacterial numbers more rapidly than chlorine or copper:silver ions alone. Numbers of S. faecalis also were reduced more in the combined system than in the system containing only free chlorine when exposed for 0.5 min. The addition of copper:silver ions allowed concentrations of free chlorine to be reduced to 0.20 mg/L while still being able to meet guidelines for swimming pool disinfectants.
