为了响应地表水处理规则和消毒副产品规则，马萨诸塞州水资源管理局（MWRA）启动了Wachusett水库供水的试点处理项目。该机构保留了CH2M希尔咨询工程师和麻州大学的目的是对这个水源进行4个季节的试点研究。本文试图描述有关消毒副产物（DBPs）、副产物前体和可同化有机碳（AOC）去除的更重要结果。这些数据以简洁的方式进行了总结，以便对其他公用事业公司和研究人员研究臭氧与颗粒介质过滤的使用可能有用。

In response to the surface water treatment rule and the disinfection byproduct rule, the Massachusetts Water ResourcesAuthority (MWRA) initiated a pilot treatment program of its Wachusett Reservoir supply. The authority retained CH2M Hill Consulting Engineers and the University of Massachusetts for the purpose of conducting a 4-season pilot study on this water source. This paper attempts to describe the more important results regarding the removal of disinfection byproducts (DBPs), byproduct precursors, and assimilable organic carbon (AOC). The data are summarized in a concise fashion so that they might be useful to other utilities and researchers examining the use of ozone with granular media filtration.
