Deficient disinfection systems enable bacteria to form in drinking water; these can invade plumbing systems even if the pipes are composed of antibacterial materials such as copper. Severe copper corrosion by microorganisms and their subsequent release into the water system are evidenced by the blue water phenomenon. Proper monitoring and control can reduce such undesirable effects on water quality. However, a lack of data from analysis under actual conditions has limited the development of useful predictive tools and preventive strategies. In this work, an experimental aging system was connected to a drinking water network affected by the blue water phenomenon. The microbially influenced corrosion (MIC) was evaluated by studying the dynamics of the formed bacterial community and its relationship with copper corrosion and the release of copper. The results suggest that the conformation and composition of the biofilm attached to the surface influence the measured parameters. The corrosion rate was variable throughout the sampling time, with the highest value recorded after one year of aging. The composition of biofilms also changed with time; however, the genus Pseudomonas was ubiquitous over the sampling time. No relationship between the corrosion rate and the biofilm age was observed, thereby suggesting that MIC is a dynamic phenomenon that requires further study.

实际饮用水条件下铜管的生物腐蚀动力学

消毒系统不足会使细菌在饮用水中形成；即使管道由抗菌材料（如铜）组成，它们也会侵入管道系统。蓝水现象证明了微生物对铜的严重腐蚀及其随后释放到水系统中。适当的监测和控制可以减少这种对水质的不良影响。然而，在实际条件下缺乏分析数据限制了有用的预测工具和预防策略的开发。在这项工作中，一个实验老化系统连接到受蓝水现象影响的饮用水网络。通过研究形成的细菌群落的动力学及其与铜腐蚀和铜释放的关系来评估微生物影响腐蚀 (MIC)。结果表明附着在表面的生物膜的构象和组成会影响测量参数。腐蚀速率在整个采样时间内是可变的，老化一年后记录的最高值。生物膜的组成也随时间而变化；然而，假单胞菌属在采样时间内无处不在。没有观察到腐蚀速率和生物膜年龄之间的关系，从而表明 MIC 是一种需要进一步研究的动态现象。在整个采样时间内，假单胞菌属无处不在。没有观察到腐蚀速率和生物膜年龄之间的关系，从而表明 MIC 是一种需要进一步研究的动态现象。在整个采样时间内，假单胞菌属无处不在。没有观察到腐蚀速率和生物膜年龄之间的关系，从而表明 MIC 是一种需要进一步研究的动态现象。
