One of the major problems facing the water industry is corrosion and sedimentation, which causes problems such as reduced water quality and the useful life of water supply network equipment. This study aimed to investigate the corrosion and sediments formed in the drinking water distribution network of Sough City. In this cross-sectional study, samples were prepared from 7 wells, water storage reservoirs, and a dedicated water supply network in this area from 2006 to 2017. The parameters included pH, TDS, water temperature, total alkalinity, calcium hardness, and total hardness indices of Langelier, Ryznar, Pokurious, and Aggressive were measured in all sources. The mean indices were -0.59 ± 0.62, 8.48 ± 0.79, 7.24 ± 0.28, and 12.01 ± 0.22, respectively. The average PSI in all seasons was more than 7, AI was equal to 12, and pH in all seasons was 7.8, but in the summer it increased slightly to 8.5. This research showed that the amount of corrosiveness and sedimentation of water is not related to physicochemical parameters. Examination of corrosion indices of the dedicated water supply network of Sough City in the summer of 2011 showed that the water of this network tends to calcium carbonate sedimentation. A magnetic field was used to remove sediments formed in this water distribution network.
水行业面临的主要问题之一是腐蚀和沉淀，这会导致水质下降和供水网络设备使用寿命缩短等问题。本研究旨在调查苏格市饮用水分配网络中形成的腐蚀和沉积物。在这项横断面研究中，从2006年至2017年从该地区的7口井、蓄水池和一个专用供水网络中采集了样本。测量了所有水源中的pH值、总溶解固体、水温、总碱度、钙硬度以及朗格利尔、赖兹纳尔、波库留斯和侵蚀性的总硬度指数。平均指数分别为-0.59±0.62、8.48±0.79、7.24±0.28和12.01±0.22。所有季节的平均PSI均大于7，AI等于12，所有季节的pH值为7.8，但在夏季略有上升至8.5。本研究表明，水的腐蚀性和沉淀量与理化参数无关。对2011年夏季苏格市专用供水网络的腐蚀指数进行检查表明，该网络的水倾向于碳酸钙沉淀。使用磁场去除该配水网络中形成的沉积物。
