本powerpoint演示文稿首先简要概述了达拉斯水务公司，并介绍了一个涉及有色水投诉的案例研究。研究设计包括 监控16个配电系统位置，以获取 为期12个月，并监测参数，包括: 酸碱度； 消毒残留物；可同化有机碳（AOC）； 生物生长指标——HPC； 硝化指标——亚硝酸盐、硝酸盐、AOB；和 腐蚀指示器——铁、浊度。导致有色水的因素如下: 离开处理厂的水被污染了 生物不稳定； 生物再生， 硝化和降低配水系统中的pH值；此外，管道水垢的浸出导致客户水龙头出现红色水。 管壁的初步研究/ 介绍了水的相互作用，以及有色水的管理 发展战略 处理厂包括 增强 凝固 生物学的 过滤和氯/氨 比例为5:1。推荐的有色水处理策略 分配 系统包括 周期性 法拉盛， 助推器 氯化和腐蚀 抑制剂 附加包括表格、数字。

This powerpoint presentation begins by providing a brief overview of Dallas Water Utilities and a case study involving colored water complaints. The study design included monitoring 16 distribution system locations for a period of 12 months, and monitoring of parameters that included: pH; disinfection residual; assimilable organic carbon (AOC); biological growth indicators - HPCs; nitrification indicators - Nitrite, Nitrate, AOB; and, corrosion indicators - iron, turbidity. Elements contributing to the cause of colored water were identified as the following: water leaving the treatment plants was biologically unstable; biological re-growth, nitrification and lowering of pH in the distribution system; and, the leaching of pipe scale resulted in red water at customer taps. A pilot study of pipe wall/ water interactions is presented, along with colored water management strategies for treatment plants including enhanced coagulation, biological filtration, and chlorine/ammonia ratio of 5:1. Recommended colored water treatment strategies for the distribution system included periodic flushing, booster chlorination, and corrosion inhibitor addition. Includes tables, figures.
