对拟建的每天3000万加仑地表水处理厂进行了一项中试研究，以评估使用颗粒活性炭（GAC）去除消毒副产物前体的效果。进行了先导前快速小规模柱试验（RSSCT），以选择用于先导试验的GAC类型。在为期六个月的中试研究中，RSSCT中使用的两种活性炭在过滤后活性炭柱中进行了测试。比较RSSCT柱和中试柱总有机碳（TOC）穿透曲线，以确定RSSCT预测中试规模TOC去除的效果。 评估了使用RSSCT进一步测试全尺寸设计方案的可行性。包括5个参考文献、表格、图表。

A pilot study was conducted to evaluate disinfection byproduct precursor removal with granular activated carbon (GAC) for a proposed 30-million gallons per day surface water treatment plant. Prepilot rapid small-scale column tests (RSSCT) were performed to select GAC types for pilot testing. Two of the GACs used in the RSSCT were tested in post-filtration GAC columns during a six-month pilot study. A comparison was made of the RSSCT column and pilot column total organic carbon (TOC) breakthrough curves to determine how well the RSSCT predicted TOC removal at pilot scale. The feasibility of using the RSSCT for further testing of full-scale design alternatives was evaluated. Includes 5 references, tables, figures.
