本powerpoint演示文稿首先提供锰化学的背景信息。列出了锰处理选项，以及锰的形态、用于锰还原的氧化剂和用于锰还原的二氧化氯。本文概述了该国东北部、东南部和落基山脉地区的三个案例研究。总结: 二氧化氯是实现这一目标的可行替代氧化剂 成品水溶性锰表面含量<20µg/L 存在总有机碳（TOC）的水处理厂， 不超过MRDL/MCL（亚氯酸盐）；二氧化氯应包括在可行性评估中 氧化除锰选项；测试必须包括对亚氯酸盐和氯酸盐产量的分析，以确保 遵守MCL； 如果可溶性锰超过0.4 mg/L，则可能需要其他氧化剂 （取决于绿泥石产量）； 注意生锰和沉淀锰的形态 浓度；和 可以产生新的氯系统 不使用氯气的二氧化碳。包括表格、数字。

This powerpoint presentation begins by providing background information on manganese chemistry. Manganese treatment options are listed, along with manganese speciation, oxidant use for manganese reduction, and chlorine dioxide for manganese reduction. Three case studies are outlined from the northeastern, southeastern and Rocky Mountain areas of the country. Summary: chlorine dioxide is a viable alternate oxidant for achieving finished water soluble manganese < 20 µg/L in surface water treatment plants where total organic carbon (TOC) is present, without exceeding the MRDL/MCL (chlorite); chlorine dioxide should be included in evaluations of feasible oxidation options for manganese removal; testing must include analysis of chlorite and chlorate yield to ensure compliance with MCL; if soluble manganese exceeds 0.4 mg/L may need other oxidants (dependant on chlorite yield); pay attention to speciation in raw and settled manganese concentrations; and, new systems exist that can generate chlorine dioxide without chlorine gas usage. Includes tables, figures.
