Application of Ice Pigging in a Drinking Water Distribution System: Impacts on Pipes and Bulk Water Quality

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 waterChloride concentration analysis demonstrated that separate cleaning of pipes with different materialsin complex networks could mitigate the risk of losing ice pigs and degrading water quality.The bacterial richness and diversity of bulk water decreased significantly after ice pigging.
