本powerpoint演示文稿首先简要介绍了位于加利福尼亚州加德纳市的金州水务公司及其腐蚀控制计划。本文介绍了该程序的目标、系统冲洗程序和主要采样参数的结果，包括: 总余氯； 异养平板计数； 顾客投诉； 花在冲洗上的时间；和 水 冲水造成的损失。 演示结论表明:在5区、6区和7区实施腐蚀控制； 对消毒剂残留的即时影响——增加； 正如预期的那样，最初提高的HPC水平和客户需求 抱怨随着时间的推移而减少； 短期消毒剂残留量低，高 HPC和更多客户投诉；应在实施 聚磷酸盐混合添加剂；在实施腐蚀控制后，几年内需要进行积极的冲洗 控制水质并将其恢复到理想状态的时间 水质目标； 添加聚磷酸盐混合物将使其软化并 去除现有的生物膜层和腐蚀产物- 这最初是一个快速，但后来是一个非常缓慢的过程 过程与去年相比，我们减少了 腐蚀控制区域的冲洗时间； 在整个系统范围内，我们能够减少水的流失 通过冲洗； 在实施腐蚀控制时，减少和减少腐蚀 仔细调整冲洗； 建立背景水质数据并进行监测 避免水质恶化的趋势 在实施腐蚀控制期间；和 最后但并非最不重要的一点是 部门对于一个成功的团队来说是绝对必要的 腐蚀控制程序。包括表格、数字。

This powerpoint presentation begins by providing a brief overview of the Golden State Water Company, located in Gardena, California, and its corrosion control program. The goals of the program are presented, along with the system's flushing program and the results of the main sampling parameters that include the following: total chlorine residual; heterotrophic plate count; customer complaints; time spent flushing; and, water loss through flushing. Presentation conclusions indicate the following: implementation of corrosion control in Area 5, 6 and 7; immediate effect on disinfectant residual - increase; as expected, initially elevated HPC levels and customer complaints that decreased with time; short-term episodes of low disinfectant residuals, high HPCs and more customer complaints; should be expected shortly after implementation of polyphosphate blend addition; aggressive flushing after implementation of corrosion control was necessary for a couple of months to control and restore water quality to desirable water quality goals; the addition of the polyphosphate blend will soften and remove existing biofilm layers and corrosion products - this is initially a fast but then a very slow process; in comparison to last year, we were able to decrease flushing time in areas under corrosion control; system-wide we were able to reduce water loss through flushing; when implementing corrosion control, reduce and adjust flushing carefully; establish background water quality data and monitor trends closely to avoid water quality degradation during implementation of corrosion control; and, last but not least, communication between departments is absolutely necessary for a successful corrosion control program.
