本powerpoint演示文稿首先简要概述了氯胺化学和硝化作用可能引起的水质问题。介绍了水源混合对硝化作用的影响，并简要概述了西部城市水区（WMWD）和拉哈布拉市的案例研究。陈述摘要和结论如下:WMWD得出结论，其 Murrieta wells将允许最大限度的操作 全年灵活； La Habra没有观察到该区域存在显著的硝化作用 系统，可能是由于冬季无氯化（即。， 倦怠）；和 公用事业公司混合氯化和硫酸的考虑因素 氯胺化源水包括混合位置——水库/水箱或管道、季节性用水——天然游离氯₂燃尽期，以及消毒副产物（DBP）形成潜力和断点的可能性 氯化。 包括表格、数字。

This powerpoint presentation begins by providing a brief overview of chloramine chemistry and water quality issues that can arise from nitrification. The impact of source water blending on nitrification is presented, along with a brief overview of case studies at Western Municipal Water District (WMWD) and at the City of La Habra. Presentation summary and conclusions indicate the following: WMWD concluded that chloramination of their Murrieta wells would allow maximum operational flexibility throughout the year; La Habra did not observe significant nitrification in the system, likely due to wintertime free chlorination (i.e., burnout); and, considerations for utilities blending chlorinated and chloraminated source waters include location of blending - reservoir/tank or pipeline, seasonal water usage - natural free Cl₂ burnout periods, and disinfection byproduct (DBP) formation potential and possibility of breakpoint chlorination. Includes tables, figures.
