辛辛那提水厂（CWW）与蒙哥马利·沃森工程公司（Montgomery Watson Engineering）联合对理查德·米勒处理厂（RMTP）进行了工厂审计。审计的结论是，可能需要对当前的水处理实践进行更改，以实现符合长期强化地表水处理规则（LTESWTR）规定的病原体去除/灭活要求。建议对装置处理工艺进行前瞻性的操作变更和修改。审计还得出结论，在开始全面示范研究之前，需要对当前的混凝剂混合系统进行改进，以证明板层/蓄水池系统能够以220 MGD的速度提供所需的处理水平。因此，安装了一个新的全尺寸快速混合系统，以改善明矾和聚合物进料系统的化学混合。安装了六台在线泵扩散混合器。前三台并联运行的搅拌机专门用于混合明矾。 其他三台搅拌机也并联运行，专门用于聚合物的混合，位于明矾搅拌机下游约1分钟（就水力停留时间而言）。在安装前后对电厂性能的影响进行了评估，并计算了回收期。本文总结了一项为期12个月的大规模高效澄清示范研究，以及对新型混凝剂闪速混合器的评估。包括4个参考文献、表格和图表。

Cincinnati Water Works (CWW) performed a plant audit in association with Montgomery Watson Engineering at the Richard Miller Treatment Plant (RMTP). The audit concluded that changes to the current water treatment practices may be warranted to achieve compliance with pathogen removal/inactivation dictated by the Long Term Enhanced Surface Water Treatment Rule (LTESWTR). Proactive operational changes and modification of unit treatment processes were suggested. The audit also concluded that prior to the start of a full-scale demonstration study improvements to the current coagulant mix system needed to be made to show that the lamella/reservoir system is capable of providing the required levels of treatment at a rate of 220 MGD. Therefore, a new full-scale, flash mix system was installed to improve chemical mixing of both the alum and polymer feed system. Six in-line pump-diffusion mixers were installed. The first three of these mixers, which operate in parallel are dedicated to the mixing of alum. The other three mixers, which also operate in parallel, are dedicated to the mixing of polymer and are located approximately 1 minute (in terms of hydraulic detention time) downstream of the alum mixers. Impact to plant performance was evaluated before and after installation, and a pay back period was calculated. This paper summarizes a twelve-month full-scale high rate clarification demonstration study and an evaluation of new coagulant flash mixers. Includes 4 references, tables, figures.
