Abstract

In previous work, the effects of water quality have been shown to influence the formation of scale from copper corrosion. A general understanding of the effects of water quality on copper corrosion have been difficult to obtain because of complex interactions of water quality variables on copper corrosion in different water supply systems. The objective of this study was to examine the effects of temperature and water hardness on copper corrosion occurring in a household water supply system. The effects of recirculation were also studied in concurrence with the above water quality parameters. Electrochemical corrosion testing and corrosion by -product release testing were used to determine the effects of temperature, water hardness, and recirculation on corrosion rates and copper corrosion by -product release. The results of this testing revealed that increasing temperature dramatically reduced copper corrosion by -product release. Temperature was shown to effect the solubility of the corrosion by -product released into solution. Water hardness had little or no effect on copper corrosion by -product release. The effects of recirculation used in this experimentation were found to be in direct relationship to the effects of temperature on corrosion by -product release.
