Abstract

The applicability of chlorine dioxide at low doses for the protection of drinking water distribution systems is evaluated. Chlorine dioxide is an efficient agent for disinfection of Aeromonas, even at low doses, provided the chlorine dioxide demand of the receiving water is low. However, because low doses of chlorine dioxide are rapidly consumed in most Dutch drinking waters and the disproportionation products in drinking water have no effect on Aeromonas, low chlorine dioxide doses are not effective in protecting distribution systems against growth of Aeromonas.
