Background & Aim: Corrosion is one of the most complicated and costly problems related to the drinking water supply that can influence the health of consumers, the general acceptance of a water resource, and the costs of water supply. Scaling also causes problems such as clogging and head loss in drinking water networks. The aim of this study was to determine the chemical quality and stability ...
Nitrifying bacteria were detected in 64% of samples collected from five chloraminated water supplies in South Australia and in 20.7% of samples that contained more than 5.0 mg of monochloramine per liter. Laboratory experiments confirmed that nitrifying bacteria are relatively resistant to the disinfectant. Increased numbers of the bacteria were associated with accelerated decays of monochloram...
