Yujing Huang,Zhiwei Chen,Guilin He,Yu Shao,Shuang Song,Feilong Dong,Tuqiao Zhang,

Engineering doi: 10.1016/j.eng.2023.09.016

Abstract: Ice pigging is an emerging technique for pipe cleaning in drinking water distribution systems.However, substantial confusion and controversy exist on the potential impacts of ice pigging on bulk waterthe microstructural features and composition of sediments and microbial community structures in bulk waterwith different materials in complex networks could mitigate the risk of losing ice pigs and degrading waterThe bacterial richness and diversity of bulk water decreased significantly after ice pigging.

Frontiers of Environmental Science & Engineering 2014, Volume 8, Issue 3,   Pages 417-426 doi: 10.1007/s11783-013-0558-4

Abstract: A red water phenomenon occurred in several communities few days after the change of water source in BeijingThe results indicated that a significant increase in sulphate concentration as a result of the new watersource was the cause of the red water phenomenon.The mechanism of iron release was found that the high-concentration sulphate in the new water source-fold higher than that occurring within the local source water.
