Metcalf&Eddy，Inc.在康涅狄格州洛克维尔的一个5 MGD常规处理厂进行了一个季度的试点研究。试点研究的目的是确定是否可以通过使用高级处理工艺来改善现有设施的性能。现有的处理厂包括两个带有GAC过滤的Periflter处理装置；中试规模试验将超脉冲发生器（r）和U型超脉冲发生器（r）装置与单介质GAC和砂滤相结合。向高级工艺中添加预臭氧和/或中间臭氧，以评估其对有机物和消毒副产品前体去除的影响。本文比较了现有设施和中试工艺去除分配系统中TOC、总三卤甲烷和卤乙酸的性能。利用深度处理处理地表水供应的好处，以及中试规模和现有工艺满足以下要求的能力:- 讨论了产品规则。

Metcalf & Eddy, Inc. performed a one-season pilot study at a 5 MGD conventional treatment plant located in Rockville, Connecticut. The purpose of the pilot study was to determine if the performance of the existing facility could be improved by using an advanced treatment process. The existing treatment plant consists of two Perifilter-treatment units with GAC filtration; the pilot scale testing utilized the Superpulsator(r) and Type U Superpulsator(r) units in combination with single media GAC and sand filtration. Pre-ozone and/or intermediate ozone were added to the advanced process to evaluate its effect on organic and disinfection byproduct precursor removal. This paper compares the performance of the existing facility and the pilot process for removal of TOC, total trihalomethanes and haloacetic acids in the distribution system. The benefits of utilizing advanced treatment to treat a surface water supply and the capability of the pilot scale and existing processes to meet the Disinfection By-Product Rule are discussed.
